  • Anode active material and anode for lithium-ion battery, method for preparing the anode active material, and lithium-ion battery
    Patent number: 10978695
    Abstract: An anode active material for a lithium-ion battery with greatly reduced recharging time includes SiO particles, graphite particles, and a carbon coating layer. The graphite particles and SiO particles are processed to form spherical SiO/graphite composite particles. A layer of carbon coating is applied to the surface of the SiO/graphite composite particle and the resulting anode active material resembles a pomegranate structure.
    Type: Grant
    Filed: December 19, 2018
    Date of Patent: April 13, 2021
    Assignee: GP Batteries International Limited
    Inventors: Xian-Wen Ren, Yu-Sum Chow, Wei-Gong Zheng, Jia-Miao Liu, Wei-Chen Hu, Kwok-Fung Kan
