Figure 3: Electrochemical performance before and after surface modification.
From: A stable lithium-rich surface structure for lithium-rich layered cathode materials
(a), The first charge–discharge voltage profiles of the pristine electrode and the surface-modified electrode with 5 wt% Li2MnO3 in the range of 2.0–4.8 V at 0.1C (25 mA g−1). (b) Comparative rate capabilities of both electrodes measured at various C-rates after the first activating cycle at 0.1C (25 mA g−1). (c,d) Cycling performance of both electrodes at (c) 1C (250 mA g−1) and (d) 3C (750 mA g−1) after the first activating cycle at 0.1C (25 mA g−1).
