Patent ID: 8481208

Claim:
A bipolar article, the article comprising: (a) a housing comprising an inside surface and an outside surface; wherein the inside surface has an arbitrary form factor which is independent of the form factor of the outside surface and is not cylindrical or prismatic; (b) a bipolar structure comprising a cathode current collector, an anode current collector, an anode, a cathode, and an electrolyte in contact with and separating the anode and cathode; wherein the anode and cathode are interpenetrating; the cathode current collector is in electronic communication with the cathode; and the anode current collector is in electronic communication with the anode; wherein the bipolar structure as a whole has an arbitrary form that is not cylindrical or prismatic; and at least one of the cathode, the anode, and their respective current collectors has an arbitrary form that is not cylindrical or prismatic and is conformal to the inside surface of the housing.
