Abstract

Abstract : Chemically doped graphene with three‐dimensional bicontinuous nanoporosity is developed for rechargeable Li‐O2 batteries. N and S doping, together with a large accessible surface area and open pore channels of the nanoporous graphene significantly enhance the cathodic reaction kinetics of Li‐O2 batteries for an ultrahigh rechargeable capacity of 10 400 mAh g −1 and a long cycling lifetime.
