(a) Charge–discharge voltage profiles at different C rates. (b) Capacity retention (left y-axis) and coulombic efficiency (right y-axis) at C/2 rate. (c) Rate capability: C/2 (blue), C (yellow), 2C (red) and 5C (green). (d) Electrochemical impedance Nyquist plots after charge–discharge cycles and the corresponding EIS collection points are indicated in (c). The charge capacity and discharge capacity are indicated, respectively, by solid and open cubes in (b) and (c).
