Publication number: 20210057734Abstract: Materials and novel methods for producing carbon anodes for Li-ion batteries are described. These materials use natural flake graphite that has been processed to improve physical properties but retains residual impurities including silicates and other silicon containing minerals that are difficult to eliminate economically. For the purposes of battery anode material production, further purification is required and traditionally uses hydrofluoric acid, adding significant cost and environmental management requirements. Alternate novel processes result in less costly and more environmentally friendly methods when compared against the standard acid purification with hydrofluoric acid. Methods for direct graphitization of unpurified spheroidized graphite material that includes a carbonaceous coating in production of a lithium ion battery anode are provided. Materials generated using these methods may be blended with artificial graphite and particulate Silicon or SiOx materials for enhanced properties.Type: ApplicationFiled: August 21, 2020Publication date: February 25, 2021Applicant: Syrah Resources LimitedInventors: Camila de Savio Silva, Peter Ian Barnes, Jens Berkan, Joseph Russell Williams, Richard V.

Patent number: 8084998Abstract: A storage voltage of a battery pack is controlled with control electronics. The storage voltage of a battery pack is sensed, and a discharge mechanism is triggered if the storage voltage is within a predetermined range of voltage, to thereby adjust the storage voltage of the battery pack to below the predetermined range of voltage, or if the storage voltage is at or above a predetermined voltage, to thereby adjust the storage voltage of the battery pack to below the predetermined voltage. Control electronics sense a storage voltage of a battery pack and trigger a discharge mechanism if the storage voltage is within a predetermined range of voltage, to thereby adjust the storage voltage of the battery pack to below the predetermined range of voltage, or if the storage voltage is at or above a predetermined voltage, to thereby adjust the storage voltage of the battery pack to below the predetermined voltage. The control electronics are coupled to an electronic device and a battery pack.Type: GrantFiled: December 31, 2009Date of Patent: December 27, 2011Assignee: Boston-Power, Inc.Inventors: Christina M.
