Patents by Inventor Nathan L. Mitchell

Nathan L. Mitchell has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • COLLOIDAL SPHERE TEMPLATES AND SPHERE-TEMPLATED POROUS MATERIALS
    Publication number: 20120067728
    Abstract: A method of making colloidal sphere templates and the sphere-templated porous materials made from the templates. The templated porous materials or thin films comprise micron and submicron-scaled spheres in ordered, disordered, or partially ordered arrays. The invention is useful in the synthesis of submicron porous, metallic tin-based and other high capacity anode materials with controlled pore structures for application in rechargeable lithium-ion batteries. The expected benefits of the resulting nanostructured metal films include a large increase in lithium storage capacity, rate capability, and improved stability with electrochemical cycling.
    Type: Application
