| Abstract: |
| [Ni0.83Co0.11Mn0.06](OH)2 precursor was firstly synthesized by coprecipitation method, and LiNi0.83Co0.11Mn0.06O2 cathode material was formed by two-stage sintering process in pure oxygen atmosphere. Ti4+ ion doping was achieved by adding nano-TiO2 in sintering process of precursor. Li[Ni0.83Co0.11Mn0.06]0.98Ti0.02O2 cathode shows an initial capacity of 185.6 mAh/g at current density of 1 C, and a capacity of 178.8 mAh/g can be obtained after 100 cycles, which corresponding retention ratio is up to 96.33%. |
