Study of Synthesis and Properties of Spinel LiNi_0.4Mn_1.5Cr_0.1O₄ as Cathode for Lithium Ion Batteries

Abstract:

Spinel compound LiNi0.4Mn1.5Cr0.1O4 was synthesized at different reaction temperature. The optimum temperature was 900 0C. The product exhibited good electrochemical properties. It delivered capacity of 128.2, 124.1 and 116.8 mAh g-1 at 0.2, 0.5 and 1C, respectively. The capacity retention was 98%, 99% and 99% after 30 cycles, respectively. The electrochemical property of compound LiNi0.4Mn1.5Cr0.1O4 was better than that of LiNi0.5Mn1.5O4.
