Method of using a bipolar electrochemical storage device
First Claim
1. A method of using a bipolar electrode element, which element comprises a laminated substrate including a first layer comprising a particulate conductive metal oxide dispersed in a resin binder, and a second layer comprising particulate carbon material dispersed in a resin binder, the metal oxide being selected from the group consisting of barium metaplumbate and the conductive oxides of titanium, tungsten, vanadium, niobium and molybdenum, a negative electrode material applied to the first layer, and a positive electrode material applied to the second layer, which method comprises:
- employing the first layer at the negative side of a bipolar electrical element;
employing the second layer at the positive side of the bipolar electrical element.

Abstract
A double layer structure for use as a capacitor or battery electrode, for use in other electrochemical systems, includes in one embodiment a first layer containing conductive transition metal oxides and a second layer which includes conductive carbon embedded in a suitable binder. For capacitor and lead-acid battery applications the transition metal containing material is used as the negative terminal substrate. Another embodiment includes a carbon layer on an electrode surface, the electrode being made from the transition metal oxide in a binder. The last mentioned carbon layer is thin, inexpensive and more conductive than a laminate layer in which the carbon is imbedded in a self-supporting binder.
