Graphene instead of graphite doping potassium ferrate for intrinsically reforming both conductivity and stability of super-iron(vi) battery.

ABSTRACT: Graphene possesses an intrinsic electronic structure and electrochemical properties that theoretically compensate for the low conductivity and poor stability of ferrate(vi) salts. A graphene coating strategy is proposed to replace graphite conductive additives, intrinsically enhancing both the conductivity and stability of potassium ferrate(vi) for battery applications. The intrinsic modification of ferrates using graphene or graphene oxide (GO) yields materials termed graphene-modified ferrates or GO-modified ferrates. Graphene's exceptional electrical conductivity significantly improves the electrical properties of ferrate(vi) battery materials. Carbon atoms in graphene provide lone-pair electrons that coordinate with ferrates, forming an electron-coordination composite structure. This i
