【摘要】 通过对尖晶石型 Li Mn2 O4进行掺杂研究 ,发现 Li Mg0 .0 2 Zn0 .0 5Mn1 .93 O4是一种很好的锂离子电池正极材料 .Li Mg0 .0 2 Zn0 .0 5Mn1 .93 O4的大电流 ( 5 0 m A/g≈ 0 .5 C)比容量可达 98m Ah/g,在稳定衰减期 ,平均每循环周期衰减0 .0 0 5 7m Ah/g.采用 Li Mg0 .0 2 Zn0 .0 5Mn1 .93 O4作为锂离子电池的正极材料 ,可以使锂离子电池在价格和循环寿命上都得到很大的改变 .
【Abstract】 LiMg 0.02Zn 0.05Mn 1.93O 4 was found to be a good cathode material for lithiumion ion battery through our study on doped LiMn 2O 4. The specific capacity of LiMg 0.02Zn 0.05Mn 1.93O 4 is 98mAh/g under high electric current (50mA/g≈0.5C). During the stable fading process, 0.0057mAh/g is lost per cycle. With LiMg 0.02Zn 0.05Mn 1.93O 4 as the cathode material, the price and cycle life of lithiumion ion battery will be ameliorated greatly.$$$$
