锂离子

The polyanionic structure has open three-dimensional frame network. The structure has little rearrangement and keeps good stability when the lithium ions de-intercalate in the cathode material.

聚阴离子结构具有开放性的三维框架结构，当锂离子在正极材料中嵌脱时，材料的结构重排很小，结构能保持良好的稳定性。

The results showed that the charge-discharge of PPy/ VXG composite cathode material was realized by doping-undoping of anions and lithium ions.

结果表明：PPy/VXG复合正极材料是通过阴离子的掺杂/脱掺杂及锂离子的嵌脱反应来实现充放电的；

Lithium ion battery has 4 times specific energy and specific power than Nickel-Cadmium battery.

由于锂离子电池的比能量密度和比功率密度均为镍镉电池的4倍以上，近年来锂离子电池以年均20%的速度迅速发展。
