Zikang Tang 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).

  • Lithium-ion battery incorporating carbon nanostructure materials
    Patent number: 7465519
    Abstract: A lithium ion battery is disclosed in which the negative electrode material comprises carbon nanostructures having no dimension greater than 2 ?m. The battery has a high reversible capacity of the order of 400 mAh/g to 500 mAh/g which can be maintained over a long cycle-life (at least 30 cycles). The carbon nanostructures may be mixed with graphite to improve conductivity. The carbon nanostructues may be synthesized using an AFI template material followed by calcination.
    Type: Grant
    Filed: September 3, 2004
    Date of Patent: December 16, 2008
    Assignee: The HongKong University of Science and Technology
    Inventors: Zikang Tang, Ping Sheng, Qi Liang, Ning Wang, Che Ting Chan

  • Synthesis of carbon nanostructures
    Publication number: 20060051282
    Abstract: A method for forming carbon nanostructures is disclosed. The method includes the steps of: (a) synthesising a microporous template material comprising crystals having no dimension greater than about 2 ?m, (b) heating the crystals in the presence of an inert gas or a mixture of an inert gas and a carbon-containing gas at a temperature of between 500° C. and 900° C., and (c) recovering carbon nanostructures by washing the heated crystals in an acid to remove the template material.
