Electrochemical and morphology analyses of bare LCO and 2% LAF-LCO electrodes. a, b Cyclic voltammograms of cells with bare LCO or 2% LAF-LCO electrodes at a scan rate of 0.1 mV s−1 in the voltage range of 3.0–4.6 V (vs. Li+/Li). c, d Top-view SEM images of bare LCO and 2% LAF-LCO electrodes before cycling and after 5 and 100 cycles at room temperature in the voltage range of 3.0–4.6 V (vs. Li+/Li) at 27.4 mA g−1. Scale bar: 20 μm and 2 μm. Source data are provided as a Source Data file
