| 摘 要： | 尖晶石型LiMn_2O_4具有资源广、电压高、成本低、无污染、安全等优点,是具有良好发展前景的锂离子电池正极材料之一。由于在使用过程中Jahn-Teller效应、锰的溶解等引起其结构塌陷,制约了材料的应用,掺杂可以有效稳定LiMn_2O_4材料的结构、抑制容量衰减等,提高循环稳定性能。综述了Co掺杂尖晶石型LiMn_2O_4正极材料的研究进展,展望了Co掺杂尖晶石型LiMn_2O_4材料的发展前景。

| Abstract: | Spinel LiMn_2O_4 has been considered as a promising cathode material for lithium ion battery since its abundant resources high Voltage,low cost and no pollution.Due to the Jahn-Teller effect and the dissolution of manganese,resulting in structural damages,which limits the application of materials.Doping can effectively stabilize the structure of Li Mn_2O_4 material,inhibit capacity attenuation,and improve circulating performance.The Co-doped spinel LiMn_2O_4 cathode materials were introduced,and the development prospects of Co-doped spinel LiMn_2O_4 materials were prospected. |
