‘Anti-aging’ chemistry taken from nature overcomes next-gen lithium battery decay

Phys.org  November 15, 2021
Degradation occurs pretty much everywhere in nature since oxygen is one of the elements most capable of attracting electrons from other atoms and molecules. Organisms often produce different types of enzymes that work to scavenge active oxygen and free radicals to alleviate the issue. Inspired by the anti-oxygen coping mechanisms in nature researchers in China developed a photostabilizer—a simple, anti-aging binder additive to the electrolyte that can scavenge the singlet oxygen atoms and free radicals as they occur. Through experimental investigation and theoretical calculation, they found that the scavenging mechanism in layered transition metal oxides-based lithium batteries delivered superior electrochemical performance, even under elevated temperatures. The findings provide a path for manipulating the cathode and electrolyte chemistry of rechargeable batteries involving chemical degradation of electrolyte…read more. TECHNICAL ARTICLE
