Korean researchers create elastic layer to improve solid-state battery lifespan and stability

Korean researchers developed an elastic material for solid-state batteries, significantly improving their lifespan and stability. The new technology uses a rubber-like polymer to absorb stress, prevent cracking, and maintain contact between battery components during charging and discharging. This enhances durability and reduces the need for high external pressure. This advancement addresses a key challenge in sulfide-based solid-state batteries, potentially leading to safer, longer-lasting, and more cost-effective batteries for electric vehicles and energy storage.
