Abstract

An electrolyte is introduced into an electrochemical device, passed, via a first corrugation feature, through a first electrode of the electrochemical device, passed through an ion permeable separator, and contacted with a second electrode. The first or second electrode comprises a second corrugation feature in fluid communication with the first corrugation feature to contact the electrolyte across a portion of an active surface of the first or second electrode.
