Figure 2. Electrochemical properties of the HR-NCM and LR-NCM cathodes in the voltage range of 2.7-4.3 V. (A) The initial charge/discharge voltage curves of both cathodes at 0.1 C. (B) Cycling performance and (C and D) the corresponding dQ dV^-1 curves at different cycles at 1 C. (E) Cycling performance at 3 C. (F) Rate capability of cathodes from 0.1 C to 15 C and the first discharge curves under various current densities of (G) HR-NCM and (H) LR-NCM cathodes.
