Latest Patents

Wang's latest patents include a method of preparation of carbon materials for use as electrodes in rechargeable batteries. This innovative method produces carbon materials that exhibit intercalation efficiencies of approximately 80% for lithium, low irreversible loss of lithium, and long cycle life. These electrodes are capable of sustaining high rates of discharge and are cost-effective to manufacture. The method involves a novel two-step stabilization process where polymeric precursor materials are first heated in an inert atmosphere and then in air. This process can be enhanced by agitating the polymeric precursor material to reduce particle fusion and promote mass transfer of oxygen and water vapor. The stabilized materials can then be converted into synthetic carbon suitable for fabricating electrodes by heating to high temperatures in a flowing inert atmosphere.

Another notable patent is for a structural micro-porous carbon anode for rechargeable lithium-ion batteries. This invention features a secondary battery that includes a rechargeable lithium-containing anode, a cathode, and a separator with an organic electrolyte solution. The anode is composed of three-dimensional microporous carbon structures synthesized from polymeric high internal phase emulsions or materials derived from this emulsion source.
