Patent for License with Right to Enforce:Polymeric electrode, Lithium ion & other metal-free, quasi-solid state primary & secondary batteries
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.
