The C rate performance of LiCr_xMn_2-xO₄ has been studied by the current pulse relaxation technique as a function of the lithium diffusion coefficients in LiCr_xMn_2-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 LiCr_xMn_2-xO₄. LiCr_0.1Mn_1.9O₄ showed the best electrochemical performance at 1C rate charge discharge cycles.
