In situ grafted carbon on sawtooth-like SiC supported Ni for high-performance supercapacitor electrodest

摘要

A novel C-Ni-SiC composite using sawtooth-like SiC as support and carbon as modified material was prepared by hydrothermal synthesis and thermochemical pyrolysis. As a supercapacitor electrode, it exhibits very high specific capacitance (1780 F g~(-1)) and excellent cycling performance (＞96% for 2500 cycles).
