Penn State Researchers Develop “All-Climate” Battery for Extreme Temperature Performance
A new lithium-ion battery design could solve one of the technology’s most persistent challenges: reliable operation across extreme. Lithium-ion (Li-ion) batteries power everything from smartphones to electric vehicles, but their performance drops sharply outside moderate temperature ranges. In cold climates, capacity and efficiency can plummet; in hot environments, overheating risks and degradation increase. Now, researchers at Penn State University have unveiled an all-climate battery (ACB) that promises stable performance in both extremes. The findings were published November 5 in Joule and mark a potential step forward in making Li-ion systems more adaptable for diverse applications — from renewable energy storage to aerospace systems. Led by Dr. Chao-Yang Wang, professor of mechanical and chemical engineering, the team built on more than a decade of thermal management research to refine how lithium-ion cells handle temperature variation. “Lithium-ion batteries were never meant for the broad range of uses we see today,” said Wang. “They were designed for personal electronics operating around 25 °C. Now they’re powering electric vehicles, data centers, and industrial systems that experience far more demanding environments.” Tackling the Temperature Tradeoff Conventional Li-ion batteries typically require external heating and cooling systems to remain within safe operating limits. These systems add weight, consume energy, and still only allow for consistent performance between roughly –30 °C and 45 °C. Previous attempts to expand this range have faced a tradeoff: improving performance in cold conditions often reduced stability in heat, and vice versa. The Penn State team’s new approach integrates a small internal heating element within the battery itself, while optimizing electrode and electrolyte materials for high-temperature resilience. This combination allows the ACB to self-regulate and maintain stable operation without heavy external systems. “Most researchers have tried to solve both hot and cold performance issues solely through materials,” Wang explained. “By optimizing for high-temperature stability and using internal heating for cold starts, we can overcome the thermal limitations without compromising safety.” Expanding Applications The ability to operate efficiently across extreme climates could open new markets for Li-ion technology. Potential applications include solar farms in desert regions, electric vehicles in cold climates, and space or satellite systems where temperature swings are severe. If further validated, the all-climate design could help reduce the complexity and cost of temperature management in large-scale battery systems — a critical step toward improving both energy efficiency and reliability in future deployments.

Cracking the Code on Lithium Battery Safety
New research reveals hidden risks in solid-state designs — and a path toward safer, longer-lasting batteries. They’re small, powerful, and packed with potential — but lithium batteries still have one explosive problem: dendrites. These tiny, needle-like metal structures can grow inside a battery, short-circuit it, and in the worst cases, cause fires or explosions. Until now, scientists believed they had a solution. Solid-state batteries, especially those using polymer-based electrolytes, were thought to be the ultimate fix — stable, solid, and far less flammable than liquid-based designs. But a team at the Technical University of Munich (TUM) has just discovered something that could change that narrative. Their research shows that dendrites can form not only at the electrodes — where they were expected — but also within the polymer electrolyte itself. That’s the very material meant to prevent these dangerous growths. “Our measurements show that dendrite growth can also occur directly inside the polymer electrolyte — in the very material designed to stop it,” says Fabian Apfelbeck, a physicist pursuing his doctorate at TUM and lead author of the study. This revelation could reshape how scientists approach solid-state battery design. To uncover this hidden process, the TUM team used a nanofocus X-ray technique at the German Electron Synchrotron (DESY) in Hamburg. With an X-ray beam just 350 nanometers wide — roughly 200 times thinner than a human hair — they watched structural changes unfold inside a working battery for the first time. The finding surprised even seasoned researchers. “We’ve long assumed dendrites only grow at the interface between electrode and electrolyte,” explains Prof. Peter Müller-Buschbaum, who leads TUM’s Chair of Functional Materials. “Seeing them form deeper inside the material challenges that assumption completely.” Understanding where dendrites form — and why — is a critical step toward creating safer, longer-lasting, and more efficient solid-state batteries. With this knowledge, researchers can now focus on developing electrolytes that stop internal crystallization before it starts. The study, “Local crystallization inside the polymer electrolyte for lithium metal batteries observed by operando nanofocus WAXS,” was published in Nature Communications in 2025.
Fluoride Revolution: Yonsei University’s High-Voltage Battery Breakthrough
In a major leap for solid-state battery technology, researchers at Yonsei University in South Korea have developed a fluoride-based solid electrolyte that allows all-solid-state batteries (ASSBs) to safely operate beyond the 5-volt barrier — a long-standing challenge in energy storage. Led by Professor Yoon Seok Jung, the team’s innovation could significantly boost both the safety and energy density of next-generation batteries used in electric vehicles and renewable energy systems. Breaking the 5-Volt Limit Conventional solid electrolytes often degrade at high voltages, limiting performance and efficiency. Yonsei’s new material — formulated as LiCl–4Li₂TiF₆ — overcomes this issue with exceptional ionic conductivity and high-voltage stability. Tests show that the electrolyte maintains structural integrity even under demanding conditions, preventing the interfacial degradation that typically hampers solid-state designs. Published in Nature Energy, the research demonstrates how the fluoride composition enables record capacity retention while remaining compatible with cost-effective cathode materials, potentially reducing manufacturing costs. Inside the Science The key lies in the material’s fluoride-rich lattice, which facilitates rapid lithium-ion transport while resisting oxidation. By fine-tuning the ratio of lithium chloride and lithium titanium fluoride, the team achieved conductivity levels that rival those of liquid electrolytes — a milestone rarely seen in solid systems. This stability minimizes side reactions at the electrode interface, allowing batteries to endure thousands of charge cycles without major capacity loss. Implications for Electric Vehicles Higher-voltage, safer batteries are critical to extending EV range and reducing fire risks associated with liquid electrolytes. Yonsei’s design could make solid-state EV batteries both safer and more energy-dense, all while maintaining compatibility with existing production lines — a key factor for large-scale adoption. Industry analysts expect the technology could reach mass-market readiness by the end of the decade, transforming how electric vehicles are powered. Applications Beyond Mobility Beyond transportation, this innovation has major implications for grid-scale energy storage. High-voltage ASSBs could store renewable power more efficiently, supporting the global transition toward sustainable electricity systems. Early lab tests suggest energy densities surpassing today’s lithium-ion batteries, positioning the fluoride electrolyte as a leading candidate for next-generation energy storage platforms. Challenges and Next Steps While the results are promising, scaling production will require cost-effective sourcing of fluoride materials and validation of long-term durability across diverse operating environments. Professor Jung remains optimistic, noting that the team’s design “enhances ionic conductivity, prevents interfacial degradation, and achieves record energy density.” Yonsei University is now developing prototype cells and exploring industry partnerships to accelerate commercialization. A New Benchmark in the Battery Race Global players such as QuantumScape and Solid Power are also pursuing high-energy solid-state systems, but Yonsei’s voltage-stability breakthrough gives it a competitive edge. The innovation reinforces Asia’s growing leadership in battery research and could set a new global standard for high-voltage performance. As the race toward more powerful, safer, and sustainable batteries continues, Yonsei’s fluoride-based electrolyte stands out as a potential cornerstone technology for the electric future.
Why Batteries Are Defining the 21st Century Economy
If oil powered the 20th century, batteries will power the 21st. Compact, quiet, and invisible, batteries have become the unseen infrastructure of modern economies — the backbone of electrification, digitalisation, and decarbonisation. From Fuel to Storage: A New Energy Paradigm For more than a century, energy systems were built around extraction and combustion. The battery revolution turns that model inside out. Energy today is captured, stored, and released with precision — a shift from burning resources to engineering electrons. Pipelines and refineries are giving way to chemistry labs and gigafactories. The age of fuel is ending; the age of storage has begun. And at its heart is the battery — the critical enabler of electric vehicles, renewable grids, industrial automation, and mobile technology. The Global Race to Store Power Energy storage has become the new frontier in the race toward decarbonisation. As renewables expand, so does the need to balance intermittent supply. Batteries fill that gap, stabilising power systems and turning solar and wind into reliable, on-demand energy sources. Investment is surging. Gigafactories are rising across Asia, Europe, and North America as countries compete to secure the minerals, technology, and manufacturing capacity that underpin the battery economy. Energy independence in the 21st century won’t be defined by oil wells — but by control over materials science, processing, and production scale. For Europe, the challenge is existential. The region’s automotive giants are racing to electrify, transforming century-old engine plants into cell assembly lines. Battery value chains are becoming the new industrial battleground — where climate goals meet economic strategy. Beyond Lithium: The Next Wave of Battery Innovation The lithium-ion battery has powered the modern world, but its chemistry is approaching its limits. A new generation is emerging: solid-state, sodium-ion, and hybrid systems that promise higher performance, faster charging, and lower environmental impact. Startups and research institutions are pushing the boundaries of energy density, recyclability, and material sourcing. These innovations could unlock a more sustainable and decentralised energy landscape — one where local manufacturing replaces global dependency and recycling replaces mining. The future of storage, like the past of oil, will be shaped by innovation and control of resources. But this time, the prize is cleaner, more circular, and more scalable. Capital, Competition, and Consolidation Building the battery economy takes immense capital — billions upfront, with returns measured in decades. Yet investors are flooding in. Analysts increasingly call batteries the “new semiconductors” — a foundational technology on which transport, energy, and computing now depend. Automakers, miners, and utilities are vertically integrating, creating alliances that blur traditional sector lines. Financial markets are treating energy storage as both infrastructure and growth technology — a dual identity that attracts institutional capital as well as venture funding. The next industrial revolution, it turns out, is being built one cell at a time. Powering the Digital World The impact of batteries stretches beyond energy and mobility. They’re also the heartbeat of the digital economy — keeping data centres, drones, satellites, and medical devices running in an increasingly electrified world. Without reliable storage, autonomy and connectivity — the pillars of modern life — would collapse. Batteries have become not just tools of convenience but instruments of national strategy. The nations that lead in battery production will shape global supply chains, alliances, and economic security for decades to come. The Invisible Engine The most remarkable thing about this revolution is its quietness. The infrastructure of the battery age hides in plain sight — embedded in devices, vehicles, and grid containers. There are no roaring engines or blazing refineries, just an invisible network of chemistry and current that powers everything. The challenge ahead is not just to build more batteries, but to build them better — sourcing materials responsibly, recycling efficiently, and ensuring equitable access to electrification. The battery is no longer just a component. It’s the defining technology of our century — silent, scalable, and indispensable. The future, quite literally, will be stored.

Toyota Targets 2028 for Solid-State Battery EV Launch
Automaker says next-gen batteries are “on schedule” and could redefine electric performance Toyota has reaffirmed its commitment to bringing solid-state batteries (SSBs) to market by 2028 — and possibly as soon as 2027 — as development of the next-generation battery chemistry stays “on schedule,” according to Keiji Kaita, President of Toyota’s Carbon Neutral Advanced Engineering Development Centre. Why Solid-State Matters Traditional lithium-ion packs are heavy, space-consuming, and slow to recharge. Solid-state cells promise to change that equation. By replacing the liquid electrolyte with a solid one, SSBs can deliver higher energy density, faster charging, improved safety, and reduced degradation over time. Kaita told reporters at the Japan Mobility Show that Toyota’s upcoming SSBs will emphasize “high power, compact size, long range and long life.” The company expects to continue using lithium-based chemistry but with far greater efficiency and longevity. Lower Carbon Footprint, Longer Life While acknowledging the environmental challenges of battery production, Kaita said the company’s approach focuses on durability as a sustainability strategy: “The most important thing is to create a high-quality battery with a long life,” he explained. “Compared to traditional batteries, the SSB’s lifespan may be four times longer. So the production carbon footprint is a quarter relatively [to a lithium-ion battery], and we think SSBs have that potential.” What Will Be First to Get SSB Tech? Toyota hasn’t yet confirmed which vehicle will debut the technology. Early speculation suggests the launch model could come from Lexus — potentially the Electrified Sport Concept or the upcoming Century luxury line — to showcase the performance and efficiency benefits of solid-state chemistry. “It needs to be a model which can leverage those qualities: high power, compact size, long range and long life,” said Kaita. “We leave it up to your imagination.” However, Toyota could also pursue scale early by deploying SSBs across its high-volume platforms, such as the next-generation Corolla, Prius, or RAV4. Doing so could deliver a decisive advantage in range, charging time, and manufacturing efficiency versus competitors. Industry-Wide Race to Commercialize Toyota is far from alone in the SSB race. Mercedes-Benz has begun public-road testing of solid-state-equipped EQS prototypes, and Croatian hypercar maker Rimac continues to invest heavily in the field. The technology has become the focus of what many are calling the most significant propulsion breakthrough since the turbocharger. Whether Toyota’s 2028 goal materializes remains to be seen, but if the company delivers on its promise, solid-state batteries could redefine both the premium and mass-market EV landscape — bringing lighter, safer, and faster-charging vehicles within reach.

Kobalt 40V Battery: Runtime, Charging Time, and Lifespan Explained
Cordless power tools have revolutionized how we work — offering the freedom to move without cords and a cleaner, more eco-friendly alternative to gas-powered machines. Yet, their biggest limitation remains the same: battery life. Even the best lithium-ion batteries can only power your tools for so long before needing a recharge or replacement. If you’re considering investing in a single brand’s cordless tool ecosystem, it’s worth knowing how much use you can expect from its batteries. One of the most popular options for outdoor tools is the Kobalt 40V platform, designed for yard equipment like trimmers, chainsaws, and lawn mowers. Here’s what to know about how long a Kobalt 40V battery lasts per charge — and over its lifetime. Kobalt 40V Battery Runtime Per Charge When it comes to battery life, two key factors matter: runtime (how long it lasts on a single charge) and lifespan (how long it lasts before it needs replacing). Runtime depends largely on the battery’s capacity — measured in amp-hours (Ah) — and the type of tool it powers. For example: Generally, higher amp-hour batteries deliver longer runtime, making them ideal for larger yards or multi-hour tasks. Charging Time and Efficiency Recharging time is another key factor to plan around. Kobalt’s 40V batteries take more than an hour to fully charge, depending on capacity: For users tackling longer projects, keeping spare batteries on hand can minimize downtime — one in use while another charges. Battery Lifespan and Warranty Like most lithium-ion power tool batteries, the Kobalt 40V battery has an average lifespan of about three years. Kobalt backs this with a three-year warranty, though actual performance varies based on usage habits and maintenance. Some users report their Kobalt 40V batteries lasting up to seven years, while others see noticeable capacity loss after two years or less. Longevity depends heavily on factors such as: Properly maintained batteries tend to last significantly longer, ensuring consistent power output and reducing the need for frequent replacements. The Bottom Line The Kobalt 40V battery system offers an affordable, reliable power source for outdoor tools, balancing performance and value. With thoughtful care and a few extra batteries in rotation, you can expect years of dependable use — and fewer interruptions when it’s time to get the job done.

New Sodium-Ion Battery Breakthrough Doubles Capacity and Desalinates Water
A research team from the University of Surrey has unveiled a major leap forward for sodium-ion batteries—and it comes with a surprising side benefit: the ability to desalinate water. The team discovered that by leaving a key battery material, nanostructured sodium vanadate hydrate (NVOH), in its natural hydrated state rather than removing the water as is typically done, the resulting batteries performed dramatically better. The redesigned cells stored twice as much charge as conventional sodium-ion batteries and maintained stability for over 400 charge cycles—putting their performance on par with some of the best cathode materials currently available. “Our results were completely unexpected,” said Dr. Daniel Commandeur, Surrey Future Fellow. “Sodium vanadium oxide has been used for years, but everyone assumed the water content was a problem. When we kept it in, the battery performed far better than anyone anticipated.” Even more striking, the researchers found that the same chemistry could be used for water desalination. The material’s behaviour in salt-water suggests a potential to not only store energy but also purify water—a dual-purpose capability that could open up entirely new applications for energy and water management. “The ability to use sodium vanadate hydrate in salt water means sodium-ion batteries could do more than store energy—they could also help remove salt from water,” Dr Commandeur explained. “In the long run, this might allow systems that use seawater as a safe, abundant electrolyte while also producing fresh water.” This innovation could have major implications for the battery-storage industry, where sodium-ion technology is rapidly emerging as a viable alternative to lithium-ion systems. Lithium-based batteries still dominate global markets, powering around 70 % of all rechargeable devices—from smartphones to electric vehicles to grid-scale storage. However, lithium’s supply chain challenges and environmental footprint are pushing researchers to explore other chemistries. Sodium, in contrast, is cheap, abundant, and widely distributed across the globe. It’s also significantly less water-intensive to extract—requiring 682 times less water per tonne than lithium. “Sodium is a much more sustainable source for batteries than lithium,” said James Quinn, CEO of UK-based battery innovator Faradion. “It’s cheaper, easier to source, and more environmentally responsible.” While sodium-ion technology is not expected to replace lithium-ion batteries entirely, many experts believe the future of energy storage will rely on a combination of both. By leveraging the strengths of each—lithium for high-density applications and sodium for cost-effective, sustainable storage—the sector can build a more flexible and resilient global energy infrastructure. The University of Surrey’s discovery adds even more momentum to that vision, offering a glimpse of a future where batteries don’t just power our devices and vehicles—they may also help solve one of the world’s most pressing resource challenges: access to fresh water.

Quantum Batteries Push Energy Extraction to the Limit
New research connects maximum battery efficiency to the principles of quantum uncertainty. Efforts to make energy storage more efficient are increasingly turning to the strange but powerful world of quantum physics. A new study by C. A. Downing and M. S. Ukhtary explores how quantum batteries—devices that store and release energy using quantum mechanical effects—can reach peak performance by obeying the Heisenberg uncertainty principle. Their findings reveal a fundamental connection between a quantum battery’s maximum extractable energy and the minimum uncertainty of its quantum state. In simple terms: when uncertainty is minimized, every bit of stored energy can be fully withdrawn. Linear coupling between a charger and a battery naturally satisfies this condition, but nonlinear coupling presents a more complex scenario. Through a process known as quantum squeezing, nonlinear systems can also achieve minimum uncertainty—unlocking new routes to optimal performance. This theoretical advance outlines how continuous-variable quantum batteries could achieve unprecedented efficiency using bosonic excitations, laying the groundwork for future photonic energy storage systems. Nonlinear Coupling Boosts Power and Capacity To explore how these effects play out, the researchers modeled the quantum battery as a system of coupled harmonic oscillators. By introducing nonlinear coupling, they examined how quantum behavior can influence charging power, energy capacity, and efficiency. Their results show that nonlinear interactions can dramatically improve both charging speed and stored energy capacity. The optimal level of nonlinearity depends on the specific design of the quantum cells and the intended operating conditions, offering a roadmap for tailoring battery behavior to different applications. This work deepens our understanding of quantum energy storage and its potential to outperform classical technologies in speed, density, and efficiency. Beyond Classical Limits Unlike conventional batteries, which rely on chemical processes, quantum batteries exploit the rules of quantum mechanics to achieve effects such as superfast charging and energy amplification.The study builds on a growing body of research into: Theoretical models—based on two-level systems, harmonic oscillators, and many-body systems—were analyzed as open quantum systems, taking into account environmental interactions and thermodynamic constraints like passivity and KMS states. Together, these insights help map the fundamental limits of energy storage and point toward practical quantum devices that could one day surpass today’s lithium-ion technology in every key metric: energy density, charging speed, and efficiency. The Road Ahead Despite these advances, turning theory into practice remains a challenge. Quantum decoherence, which causes fragile quantum states to collapse, is a major obstacle. Progress in materials science and nanofabrication will be crucial to creating real-world devices that can sustain the required quantum behavior. As this research shows, quantum batteries could redefine what’s possible in energy storage—if the physics can be mastered at scale. 🔍 Further Reading Paper: Energy storage in a continuous-variable quantum battery with nonlinear couplingAuthors: C.
