  • Negative active material, electrochemical device that uses same, and electronic device
    Patent number: 11967718
    Abstract: A negative active material includes a carbon material. The carbon material satisfies the following relationship: 6<Gr/K<16, Gr is a graphitization degree of the carbon material, measured by X-ray diffraction; and K is a ratio Id/Ig of a peak intensity Id of the carbon material at a wavenumber of 1250 cm?1 to 1650 cm?1 to a peak intensity Ig of the carbon material at a wavenumber of 1500 cm?1 to 1650 cm?1, and is measured by using Raman spectroscopy, and K is 0.06 to 0.15.
    Type: Grant
    Filed: December 2, 2022
    Date of Patent: April 23, 2024
    Assignee: NINGDE AMPEREX TECHNOLOGY LIMITED
