Reducing the overpotential of an aprotic Li–O2 battery using a conductive graphene interlayer

An aprotic Li–O2 battery incorporating a conductive graphene interlayer displays an ultralow overpotential of 0.67 V and a stable cyclability over 200 cycles at a high current density of 500 mA g−1. The improved performance of the battery is attributed to the role of the graphene interlayer in boost...

Summary:An aprotic Li–O2 battery incorporating a conductive graphene interlayer displays an ultralow overpotential of 0.67 V and a stable cyclability over 200 cycles at a high current density of 500 mA g−1. The improved performance of the battery is attributed to the role of the graphene interlayer in boosting the formation and decomposition of discharge products.
