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.
UT Dallas Solves a Decades-Old Lithium Mystery
Researchers at the University of Texas at Dallas (UT Dallas) have cracked a long-standing problem that’s hindered the commercialization of lithium-nickel-oxide (LiNiO₂) batteries—a promising material for durable, longer-lasting lithium-ion power. What’s the Issue? LiNiO₂ has long held potential as a next-gen cathode material for batteries, offering the prospect of significantly extended life. Yet recurring degradation during repeated charge cycles has blocked its path to real-world use. Until now, the root cause remained unclear. The Breakthrough UT Dallas engineers, part of the BEACONS initiative (a $30 million Department of Defense–backed program launched in 2023), dove into the breakdown process using advanced computational modeling. Their atomic-level analysis revealed a surprising culprit: a chemical reaction involving oxygen atoms within the LiNiO₂. This reaction destabilizes the cathode structure, leading to cracking and degradation over time. Once the degradation mechanism was understood, the team devised an elegant solution: reinforcing the cathode by introducing positively charged ions—“pillars” that bolster the material’s structural integrity and prevent the splitting caused by oxygen dynamics. From Idea to Prototype With this conceptual fix in hand, UT Dallas is shifting into development mode. Matthew Bergschneider, a doctoral student and first author of the study, is setting up a robotics-driven lab that will automate the synthesis and testing of the strengthened LiNiO₂ cathodes. The plan is to begin with small-scale prototypes and scale up to producing hundreds of batteries per week—paving the way for full commercialization.
