Accelerating discharging. (a) Discharging can be accelerated by applying voltage inversion, i.e., by dropping the voltage to Uinv and sweeping it to zero with rate kinv. The top plot shows examples of the voltage inversion protocol and the bottom plot compares their application with step-voltage discharging as obtained by MD simulations. (b) Voltage inversion in experiments with novolac-derived carbon and [EMIM]+-[BF4]– ionic liquid as electrolyte. Adapted with permission from ref (316).
