Effect of different anode electrodes with Li(Li 0.25 Co 0.37 Mn 0.38 )O 2 as cathode material on Li: ion battery performance

In the present work, Li-rich layered Li(Li 0.25 Co 0.37 Mn 0.38 )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 Ω, 3.89 × 10 –11 S −1 cm 2 , and 5.26 mAhg −1 and 16 Ω, 20.78 × 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.
