Abstract:
1. A method for manufacturing an electrode of a supercapacitor, comprising: (A) providing a carbon substrate and a phosphorus-containing precursor, and mixing the carbon substrate and the phosphorus-containing precursor at a ratio of 1:100 to 1000:1 by weight to form a mixture, wherein the carbon substrate is activated carbon, carbon fiber, carbon nanotube, graphite, graphene, carbon capsule, or a combination thereof; (B) heating the mixture of the carbon substrate and the phosphorus-containing precursor to a temperature between 300° C. and 1100° C. to obtain a P-doped carbon substrate; and (C) forming an electrode of a supercapacitor by using the P-doped carbon substrate.
