Full Performance Nanoporous Graphene Based Li-O2 Batteries through Solution Phase Oxygen Reduction and Redox-Additive Mediated Li2O2 Oxidation

A full-performance rechargeable Li-O-2 battery is developed by utilizing a nano-porous graphene cathode integrating with a compatible redox additive in a dimethyl sulfoxide based electrolyte. This battery system promotes the solution phase growth of Li2O2 for a large capacity and efficient decomposition of Li2O2 at a low charge potential, shining lights on practical implementations of Li-O-2 batteries for high energy applications.
