Description
technical field [0001] The invention relates to a rapid preparation method of a manganese oxide / carbon sphere composite material for 3D printing, belonging to the technical field of preparation and application of organic carbon materials. Background technique [0002] Supercapacitor has the characteristics of large capacity, short charging time, long service life, energy saving and environmental protection. It is a new type of energy storage device. [0003] The electrode materials of supercapacitors are mainly carbon materials. The electrodes made of ordinary carbon materials have low specific capacitance and small capacity, which limits the application prospects of carbon materials as electrodes. [0004] In order to enhance the specific capacity of supercapacitors, metal oxides are often deposited on the surface of carbon-based materials, which can effectively solve the problem of low specific capacitance; among many metal oxides, manganese oxide has high specific capacit...
