Electrochemical performance of bare Li/LCO cells and Li/LAF-LCO cells. a Cycling performance of half-cells with bare LCO or LAF-LCO electrodes at room temperature in the voltage range of 3.0–4.6 V (vs. Li+/Li) at current density of 27.4 mA g−1. b Long-term cycling performance of half-cells with bare LCO or 2% LAF-LCO electrodes at room temperature in the voltage range of 3.0–4.6 V (vs. Li+/Li) at current density of 27.4 mA g−1. c Discharge-charge profiles of half-cells with bare LCO or 2% LAF-LCO electrodes at different cycles in the voltage range of 3.0–4.6 V (vs. Li+/Li) at current density of 27.4 mA g−1. d Rate performance of half-cells with bare LCO and 2% LAF-LCO electrodes at room temperature in the voltage range of 3.0–4.6 V (vs. Li+/Li). All cells were pre-cycled for two cycles at a low current density of 13.7 mA g−1. Source data are provided as a Source Data file
