Abstract:
N icke l hydrox ide doped w ith and w ithout Cu were synthes ized by so lid-state reaction at lowheating tem perature. Then they w ere annea led in a ir a t 300℃ to obta in n ickel ox ide. The e lectrochem ica l m easurem ents show ed that the better d ischarge caac ity o f N iO cou ld be obta ined w hen the m ole ra tio o f N i to Cu w as 100:0. 25, w ith the spec ific capac itance a round 99~ 120 F /g, and tha t o f the undoped samp le a round only 83~ 111 F/ g.
