The invention relates to a
graphene / MXene
composite electrode material and application thereof. The
graphene / MXene
composite electrode material comprises two materials of
graphene and MXene. A preparation method of the graphene / MXene
composite electrode material comprises the steps of uniformly mixing a graphene
oxide suspension liquid and an MXene material suspension liquid, adding hydrazine
hydrate and the performing reduction, freezing and
drying to obtain the graphene / MXene composite
electrode material, wherein the
mass ratio of graphene
oxide and the MXene material is 1:(0.05-0.5). When graphene and MXene are combined, an irregularly-shaped MXene
particle material can be used as an
insertion agent and a dispersing agent and enters graphene sheet
layers, the agglomeration effect amongthe graphene sheet
layers is overcome, and the available specific area of the graphene / MXene composite
electrode material is expanded; and moreover, the MXene material has excellent hydrophilcity andconductivity, and thus, the electrochemical performance and the
capacitance deionization performance of the
composite material can be further improved.
