| Abstract: | Recent advances in synthesis of cathode material for Lithium-ion batteries were reviewed in detail. Effects of different doped-ions and surface modifications on the properties of materials were discussed. Stoichiometric LiNiO_2 phase can be obtained by controlling the synthesis conditions carefully and optimizing the synthesis technologies. Solid solutions of the cathode material with high charge-discharge capacity, excellent recycling and good thermal stability can be obtained by co-doping and surface modification technology. |
