摘要：

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. © 2015 WILEY-VCH Verlag GmbH & Co.
