oxidation method. The effects of cobalt salt, precipitating agent, surfactant, solvent, pH value of the suspension and the amount of oxidant H2O2 on the morphology and structure of Co3O4 were investigated...-controlled Co3O4 nanocubes are as follows: Co(CH3COO)2·4H2O as cobalt salt, KOH as precipitating agent, polyethylene glycol with relative molecular mass of about 20 000 as surfactant, water-n-butanol......
Effects of sodium substitution on properties of LiMn2O4 cathode for lithium ion batteries GUO Hua-jun(郭华军)1, LI Xiang-qun(李向群)2, HE Fang-yong(何方勇)1, LI Xin-hai(李新海)1, WANG Zhi-xing(王志兴... structure without impurity. The lattice constant and unit cell volume decrease with increasing the sodium dopant amount. As the molar ratio of sodium to manganese (x=n(Na)/n(Mn)) increases from 0......
