Abstract:Spinel compounds LiNi0.5Mn1.3Ti0.2O4 (LNMTO) and Li4Ti5O12 (LTO) were synthesized by different methods.The particle sizes of LNMTO and LTO are 0.5-2 and 0.5-0.8 μm,respectively.The LNMTO/LTO cell exhibits better electrochemical properties at both a low current rate of 0.2C and a high current rate of 1C.When the specific capacity was determined based on the mass of the LNMTO cathode,the LNMTO/LTO cell delivered 137 mA.h.g-1at 0.2C and 118.2 mA.h·g-1at 1C,and the corresponding capacity retentions after 30 cycles are 88.5％ and 92.4％,respectively.
