Abstract

An electrochemical device (such as a battery) includes at least one electrode having a fluid surface, which may employ a surface energy effect to maintain a position of the fluid surface and/or to modulate flow within the fluid. Fluid-directing structures may also modulate flow or retain fluid in a predetermined pattern. An electrolyte within the device may also include an ion-transport fluid, for example infiltrated into a porous solid support.
