Patent for License with Right to Enforce:

Polymeric electrode, Lithium ion & other metal-free, quasi-solid state primary & secondary batteries    

Consumer mobile sheet batteries & lightweight automotive batteries with high efficiency, capacity & voltage, and with chemically stable cycling.

Overview

These inventions provide a method for producing a quasi-solid state charge storage device capable of being repeatedly charged and discharged, having one or more electrochemical cells with a structure capable of being stacked or combined to form primary or secondary battery devices, each cell composed entirely of an ionically conducting gel polymer electrolyte layer separating opposing surfaces of electronically conducting conjugated polymeric anode and cathode electrodes supported on lightweight porous substrates; a method of forming conjugated polymers into large area composite electrode structures with practical levels of charge storage capacity; and a quasi-solid state charge storage device produced by the above methods.

An electrochemical supercapacitor or lithium ion intercalation battery can be formed from carbon particles distributed in a carbon/ceramic composite paste preferably produced by sol-gel technology wherein the paste is shaped and contacted with a solvent and electrolyte salt followed by an optional washing with an aqueous or non-aqueous solution to remove residual organic solvent and salt and leaving a shaped composite having the internal microscopic surface area electrochemically accessible and useful for charge storage applications.

The inventions also relate to a method of fabricating and/or conditioning electrically conductive and electrochemically oxidizable and/or reducible polymeric electrodes for use in a battery or electrochemical storage cell, in particular a secondary cell. A battery or electrochemical storage cell utilizing an electrode conditioned by the method of the present invention can be at least substantially free, or completely free, of metal components.

The seller may consider selling these patents individually.
