Hierarchically porous graphene for batteries and supercapacitors


As the rapidly increased energy consumption, energy storages devices with low-cost, environmental friendliness and long life span are in highly imperative. Recently, hierarchically porous graphene (HPG) based electrode materials have received widespread attention due to their unique porous structures and outstanding intrinsic properties such as high specific capacity, good rate capability, pollution-free, and excellent conductivity. The hierarchically porous structure is beneficial for the charge transfer at the electrode/electrolyte interface and the ion diffusion, and it can also accommodate volume changes during cycling. Moreover, the exsitence of a large number of defects in the basal plane of graphene increases the number of electrochemical active reversible storage sites. These advantages make HPG promising materials for electrochemical energy storage devices with flexible, stable, inexpensive, high gravimetric and volumetric current density. This perspective paper focuses on the recent works on HPG based materials and their applications in batteries (such as lithium-ion batteries and post lithium-ion batteries) and supercapacitors.
