Observation of redox product in lithium-oxygen battery

Lithium-oxygen batteries have exceptional higher energy densities. However, the byproduct lithium peroxide, cannot be easily decomposed during the charging cycle. Now, the work led by researchers from Johns Hopkins University have used Hummingbird Scientific’s liquid electrochemistry TEM holder to demonstrate that the decomposition of lithium peroxide can be improved by adding redox mediators as charge-transfer agents. Their findings are published in the recent issue of Advanced Materials. The fundamental understanding of the lithium-oxygen electrochemistry presented in this work may enable the development of better batteries
