Disclosed herein are polymer conductive films for use with electrochemical devices. An exemplary electrochemical device can include an anode, a cathode, and a bipolar structure disposed between the anode and cathode. The bipolar structure includes a film having a plurality of conductive particles and a plurality of non-conductive polymers, wherein the polymers are integrated with the particles such that the film is non-porous and substantially compositionally homogeneous along a length and/or thickness of the film.

Bipolar structures for use with electrochemical devices, and associated systems and methods

A method of making a single carbon sheet for an electrode includes mixing activated carbon; adding a dispersion comprising a PTFE binder and water to the activated carbon to form a mixture; adding the mixture to a jet mill, and fibrillating the PTFE binder; and feeding the mixture with fibrillated PTFE to a roll mill to form a single carbon sheet in a single pass.
