Description

technical field [0001] The invention belongs to an electrode material in a supercapacitor and a preparation method thereof, in particular to a poly(5-cyanindole) film electrode of a porous nanostructure of a supercapacitor. Background technique [0002] Supercapacitors are a new type of energy storage device with the characteristics of high power, instantaneous high current charge and discharge, long service life and energy saving. Supercapacitors can provide ultra-high current power, which can be used for vehicle starting power, vehicle traction energy and pulse energy for laser weapons. In my country's "Tenth Five-Year Plan" 863 electric vehicle special project, supercapacitors have been listed as a special topic for research, which fully demonstrates that supercapacitors have broad application prospects and contain huge economic benefits. [0003] Electrode materials are the core components of supercapacitors, which are mainly divided into three types: carbon-based mater...
