"Improved charging performance of Li-O2 batteries by forming Ba-incorporated Li2O2 as the discharge product"

Although Li-O2 batteries are expected as next-generation secondary batteries, large overvoltage in the charging process is one of the problems to be overcome. In this study, we found that addition of barium (Ba) ion into the electrolyte leads to the reduction of the overpotential during the charging process.
