Through the calculating of doping materials, we can see electrons are easy to transation or transfer, which strengthens the conduction properties of materials. Especially the stability of materials doping with Mn or Al is more strong, and the ionizing energy is more lower. These indicate that the electrons in the outest orbit are easier to lose, that is to say the Li+ ions are easier to imbed into materials. The discharge voltage of material doping with Co decreases, the oxidization of electrolyte is more difficult, and the cycling performance is improved.

通过对掺杂材料的计算可见掺杂后电子更容易跃迁或转移，增强了材料的导电性能，其中掺锰和掺铝的材料稳定性更强，电离能降低，说明失去最外层电子更容易，也就是说锂离子在材料中嵌入和脱出更加容易；掺钴之后材料的放电电压降低，电解液氧化的可能性减小，循环性能得到改善。
