Posco, Korea University cut voltage loss in next-gen battery cathodes

What happened: Posco Holdings and Korea University developed a heat-treatment method that improves the performance and lifespan of next-generation lithium-ion batteries by adjusting temperatures without changing the materials' chemical composition. Key numbers: After 500 charge-discharge cycles, lower-temperature cathodes showed Why it matters: The findings suggest manufacturers could improve LMR cathode durability by optimizing existing production processes without new materials, offering a practical route toward commercial production of high-capacity cathodes for EVs and energy storage.
