(a) Discharge/charge profiles of the tenth run at varied current densities from 250 to 500 and 1,000 mA g−1. (b) Discharge/charge profiles of the selected runs over the 200 cycles at 500 mA g−1. The cell was at rest for 1 min between each run. (c) Plot of discharge/charge capacities and the corresponding coulombic efficiencies against cycle number and error bars (s.e.m.) in the first 100 cycles.
