First Claim
1. A method for producing a bipolar device comprising:
- providing a medium, a first electroactive material and a second electroactive material, wherein the medium is electronically-insulating and ionically-conductive;
combining the first and second electroactive materials and the medium, wherein the first electroactive material has lower density than the second electroactive material and the first and the second electroactive materials float or sink at a different rate in the medium;
segregating at least a portion of the first electroactive material into a first spatial region that is essentially free of the second electroactive material to form a first network of electronically-connected first electroactive material; and
segregating at least a portion of the second electroactive material into a second spatial region that is essentially free of the first electroactive material to form a second network of electronically-connected second electroactive material.

Abstract
An energy storage device includes a first electrode comprising a first material and a second electrode comprising a second material, at least a portion of the first and second materials forming an interpenetrating network when dispersed in an electrolyte, the electrolyte, the first material and the second material are selected so that the first and second materials exert a repelling force on each other when combined. An electrochemical device, includes a first electrode in electrical communication with a first current collector; a second electrode in electrical communication with a second current collector; and an ionically conductive medium in ionic contact with said first and second electrodes, wherein at least a portion of the first and second electrodes form an interpenetrating network and wherein at least one of the first and second electrodes comprises an electrode structure providing two or more pathways to its current collector.
