Description

technical field

[0001] The invention belongs to the interdisciplinary field of nanomaterial preparation methods and electrochemical applications, and specifically relates to a Co 3 S 4 @MoS 2 Preparation method and application of core-shell structure nanosheet array material. Background technique

[0002] With the continuous upgrading of portable electronic products, the research on electrode materials for supercapacitors has attracted great attention from researchers. At present, the traditional supercapacitor electrode materials mainly include the following categories: porous carbon materials, metal oxides, and conductive polymers. However, these traditional, single-component electrode materials have more or less certain defects in practical applications, such as: poor conductivity, small active specific surface area, low specific capacitance, poor cycle life, low energy density and power density Small defects, due to the existence of these defects, it is difficult to ...
