Liu Hongfang 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).

  • CARBON MATERIAL SUPPORTED HOLLOW METAL OXIDE NANOPARTICLES, METHODS AND APPLICATIONS
    Publication number: 20180321176
    Abstract: A method for preparing a material composition comprising a hollow transition metal oxide nanoparticle supported upon a carbon material support includes a solution impregnation process step, followed by a thermal reduction process step and finally a thermal oxidation process step. The material composition, an electrode and an electrical component such as but not limited to a battery are all predicated at least in-part upon the material composition prepared in accord with the foregoing method. The foregoing material composition, electrode, battery and method may ultimately provide a LIB with enhanced performance.
    Type: Application
    Filed: July 9, 2018
    Publication date: November 8, 2018
    Inventors: Yingchao Yu, Héctor D. Abruña, Deli Wang, Weidong Zhou, Liu Hongfang, Qin Shuang
