Abstract

original image

On page 3699 Xin-Bo Zhang and co-workers report the synthesis of free-standing hierarchically porous carbon (FHPC) derived from a graphene oxide gel in nickel foam by a facile in situ sol-gel method. As a cathode for Li-O2 batteries, the FHPC electrode exhibits a large capacity and high rate capability. This study opens up a promising strategy for the development of high-efficient oxygen electrodes for Li-O2 batteries.
