| 摘 要： | 随着移动电子设备的飞速发展，锂电池作为新型的能源载体也取得了巨大的进步。与嵌入式氧化物正极材料相比，Li2FeS2不仅具有理想的循环性能，而且其理论容量达到400mAh／g，约为嵌入式氧化物正极材料的2倍。因此，本文从晶体结构、电化学性能、充放电机制、充放电过程中的离子电导率变化以及热稳定性等方面对Li2FeS2正极材料进行了详细的阐述。

| Abstract: | With the rapid development of mobile electronic devices, lithium - ion battery as a new energy carrier has made great progress. Compared with embedded oxide anode material, Li2FeS2 not only has the ideal cycle performance, and its theoretical capacity of 400 mAh/g, about 2 times of embedded oxide cathode material. Therefore, this article from the crystal structure, electrochemical properties, ionic conductivity change in the process of charging and discharging mechanism, charge and discharge and the thermal stability of Li2FeS2 cathode material in detail in this paper. |
