Cracking the code on solid-state batteries

Researchers are working to enhance battery safety and efficiency by developing solid-state alternatives to lithium-ion batteries. These batteries offer improved energy efficiency and safety, but a major challenge has been the formation of an interphase layer at the junction of the solid electrolyte and cathode. This ultra-thin layer obstructs lithium ion and electron movement, increasing resistance and degrading battery performance.
