EW on a superhydrophobic honeycomb membrane. (a) Without voltage, electrolyte forms a superhydrophobic “rolling ball” state on top of the membrane-filter sandwich structure. (b) Upon application of voltage, the liquid penetrates the membrane and spreads rapidly into the hydrophilic separator. (c) SEM image of the membrane in contact with an underlying hydrophilic separator made of a glass fiber filter.

Voltage output of the battery is zero until the trigger voltage is applied, after which the voltage output goes to the open-circuit voltage of .
