In the present work, Li-rich layered Li(Li0.25Co0.37Mn0.38)O2 (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 (Rct), lithium diffusion coefficients, and discharging capacity are found to be 16,242 Ω, 3.89 × 10–11 S−1 cm2, and 5.26 mAhg−1 and 16 Ω, 20.78 × 10–8 S−1 cm2, 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. [ABSTRACT FROM AUTHOR] |
