| Abstract: | Li (Ni1/3Co1/3Mn1/3)O2 was modified by silver via a silver mirror reaction.The surface elemental distribution analysis show that silver is uniformly distributed on the surface of Li(Ni1/3Co1/3Mn1/3)O2 particle.The specific discharge capacity of the bared material was 168,160 and 146 mAh/g at C/5,C/2 and 1 C rate,and the specific discharge capacity of the silver modified material was 159,149 and 140 mAh/g at C/5,C/2 and 1 C rate.However,after 50 cycles,the capacity retention of the capacity retention of the ... |
