Effect of different anode electrodes with Li(Li0.25Co0.37Mn0.38)O2 as cathode material on Li: ion battery performance

In the present work, Li-rich layered Li(Li0.25Co0.37Mn0.38)O-2 (LiCMO) material is prepared using sol-gel technique. The effect of calcination temperature on the structural and morphological characteristics of LiCMO is studied. The electrochemical performance of layered LiCMO/graphite (Cell 1) and LiCMO/Li (Cell 2) has been investigated. The charge transfer resistance (R-ct), lithium diffusion coefficients, and discharging capacity are found to be 16,242 omega, 3.89 x 10(-11) S-1 cm(2), and 5.26 mAhg(-1) and 16 omega, 20.78 x 10(-8) S-1 cm(2), and 323 mAhg(-1) for Cells 1 and 2, respectively. The presence of efficient lithium-ion transfer tendency and minimal kinetic barrier for lithium diffusion results in enhanced electrochemical properties of Cell 2. Appreciable results for (LiCMO/Li) coin cell make it a unique combination of LiCMO as cathode with Li as anode for the high energy density lithium-ion battery.
