Fast recharge of the hybrid electrode.

(a), Voltage profile during charge (green) and relaxation (gray) sequences. Top panel: relaxation periods of 30 minutes; bottom panel: 30 and 10 seconds. The effective charge duration for each step is highlighted. The apparent charge time is 1 hour and 5 minutes respectively. (b), Corresponding discharge profiles (red curves, rate of 1 C) as well as the discharge profile for constant-current charge mode for an equivalent period of time, 1 hour and ~5 minutes respectively (grey curves, rate of 1 C).
