  • Patent number: 9061902
    Abstract: Electrodes, batteries, methods for use and manufacturing are implemented to provide ion-based electrical power sources and related devices. Consistent with one such method, a battery electrode is produced having nanowires of a first material. The electrode is produced using a single growth condition to promote growth of crystalline nanowires on a conductive substrate and of the first material, and promote, by maintaining the growth condition, growth of an amorphous portion that surrounds the crystalline nanowires.
    Type: Grant
    Filed: December 18, 2009
    Date of Patent: June 23, 2015
    Assignee: The Board of Trustees of the Leland Stanford Junior University
    Inventors: Li-Feng Cui, Candace K. Chan, Riccardo Ruffo, Hailin Peng, Yi Cui
  • Patent number: 8993165
    Abstract: The present disclosure is directed at clathrate (Type I) allotropes of silicon, germanium and tin. In method form, the present disclosure is directed at methods for forming clathrate allotropes of silicon, germanium or tin which methods lead to the formation of empty cage structures suitable for use as electrodes in rechargeable type batteries.
    Type: Grant

  • Patent number: 8968929
    Abstract: The present disclosure is directed at an electrode and methods for forming such electrode for a battery wherein the electrode comprises silicon clathrate. The silicon clathrate may include silicon clathrate Si46 containing an arrangement of 20-atom and 24-atom cages fused together through 5 atom pentagonal rings and/or silicon clathrate Si34 containing an arrangement of 20-atom and 28-atom cages fused together through 5 atom pentagonal rings. The silicon clathrate may be present as particles having a largest linear dimension in the range of 0.1 ?m to 100.0 ?m.

  • Patent number: 8877374
    Abstract: A variety of methods and apparatus are implemented in connection with a battery. According to one such arrangement, an apparatus is provided for use in a battery in which ions are moved. The apparatus comprises a substrate and a plurality of growth-rooted nanowires. The growth-rooted nanowires extend from the substrate to interact with the ions.
