高倍率LiCo_xNi_yMn_zO_2锂离子电池的研究

Research on the high-rate LiMn_xNi_yCo_zO_2 Li-ion batteries

详细讨论了由镍、钴、锂锰氧化物制作的高倍率型18650LiMnxNiyCozO2锂离子电池在常温下的高倍率电性能、安全性能和贮存性能,发现由该材料制作的18650锂离子电池不仅容量高,大电流循环性能好,而且安全性优于钴酸锂,贮存性能优越。

The 18650 Li-ion cell was made with LiMnxNiyCozO2 as the positive electrode materials.And its high rate performance, safety and storage performance were introduced in this paper. It was found that the cell not only had high capacity, better high-rate discharging performance, but also had better safety performance than the cell made with LiCoO2 as the positive electrode material, and it had excellent storage performance at normal temperature.
