LiCrxMn2-xO4的倍率放电特性
摘要:
研究了LiCrxMn2-xO4的倍率充放电性能,用脉冲电流松弛法测定了LiCrxMn2-xO4中Li+的化学扩散系数,讨论了掺杂对其倍率放电性能影响的机理.结果表明,适当增加掺杂量,可加快Li+的化学扩散速度,抑制Jahn-Tellar效应,改善LiCrxMn2-xO4高倍率充放电性能.在1C倍率充放电时LiCr0.1Mn1.9O4的综合性能最佳.

On the C-rate Performance of LiCrxMn2-xO4
Abstract:
The C rate performance of LiCrxMn2-xO4 has been studied by the current pulse relaxation technique as a function of the lithium diffusion coefficients in LiCrxMn2-xO4. The results revealed that the increment of the doped chromium ion can accelerate the diffusion rate of lithium ion, reduce the Jahn-Tellar effects, and improve the rate capacity and cycle life at higher C rates for LiCrxMn2-xO4. LiCr0.1Mn1.9O4 showed the best electrochemical performance at 1C rate charge discharge cycles.
