Description

technical field [0001] The patent of the present invention relates to an electrode material, in particular to a preparation method of a nickel molybdenum sulfide / foam nickel electrode material. Background technique [0002] Supercapacitors, as an energy storage device, have the advantages of both traditional capacitors and energy storage batteries. They have the advantages of high density, fast charging, and long cycle life. They can be widely used as power sources for electronics and electric vehicles. Among many supercapacitor materials, transition metal sulfides have good electron transport ability and mechanical and thermal stability, which make them have good cycle performance and rate performance, and are very promising supercapacitor materials. [0003] At present, there are literatures reporting the application of nickel molybdenum sulfide in supercapacitors, but single nickel molybdenum sulfide has the defect of low specific capacity. Patent CN104841459A uses nicke...
