The invention provides a flexible heterogeneous nanosheet pseudocapacitance anode material, and relates to the field of capacitor manufacturing. The preparation steps are as follows: (1) performing hydrophilic and silver plating treatment on the carbon cloth; (2) preparing a tin-antimony precursor array of the super capacitor anode material; (3) preparing a tin-antimony alloy nanosheet array by adopting an in-situ reduction method; (4) preparing a positive electrode material of a tin-antimony alloy-tin antimony sulfide heterogeneous nanosheet. The anode material directly grows on three-dimensional carbon cloth, has a tin-antimony alloy-tin antimony sulfide heterogeneous nanosheet array structure, and has the characteristics of high purity, high density and high orientation; the anode material is neat in appearance, strict and controllable in growth conditions, simple in equipment and process, high in capacitance, good in charge and discharge stability and wide in application prospect. |
