The invention discloses an electrode material for constructing a core-shell structure with nickel foam as a base, belonging to the field of electrode materials; the electrode material uses nickel foam as a base, and firstly, a hydrothermal method is used to grow high specific surface area and high specific capacity on the foam nickel in situ. The sheet-sheet structure copper oxide-graphene oxide composite material is used as a "core" electrode material, a two-dimensional sheet metal oxide, which can prevent graphene agglomeration and form multilayer graphene with good mechanical stability; Electrodeposition supports Ni3S2 nanoparticle arrays, which are more conductive than metal oxides, on the "core" surface as the "shell" electrode material, because in addition to the higher conductivity, the theoretical specific capacity of Ni3S2 is also low. higher, the electronegativity of the sulfur atom is lower and exhibits better conductivity and reactivity. |
