Figure 4. Electrochemical performance and kinetic analysis of the LR-FCG and LR-113 cathodes in half-cells. (A) Comparison of the initial charge-discharge curves at room temperature (RT) within 2.0-4.8 V at 0.1 C (1 C = 250 mA g^-1); (B) The corresponding differential capacity (dQ/dV) curves; (C) Rate capability at various current densities; (D) Cycling performance at 1 C within the voltage window of 2.0-4.6 V at RT; (E) GITT curves obtained during the second cycle; (F) Comparison of the calculated Li⁺ diffusion coefficients (D_Li⁺) during the charge and discharge processes. LR-FCG: Li-rich layered oxide; GITT: galvanostatic intermittent titration technique.
