The graphene aerogel (GA) cathode has unique properties with a hierarchically porous structure that facilitates electrolyte permeation and oxygen diffusion, three-dimensional network structures that can enable easy electron transfer through GA, high specific surface area that offers abundant active sites for electrochemical reaction and an ultra-large pore volume that can accommodate plenty of discharge products. Ru nanoparticles supported on graphene sheets also has superior catalytic activity toward oxygen evolution reaction and can efficiently catalyze the decomposition of the discharge product Li2O2.
