  • Negative electrode material for lithium battery
    Patent number: 9299978
    Abstract: A negative electrode material for a lithium ion battery, in which a fine particle (A) containing an element selected from Si, Sn, Ge and In and a carbon particle (B) obtained by heat-treating a petroleum-based coke and/or a coal-based coke at a temperature of 2,500° C. or more are connected through a chemical bond such as urethane bond, urea bond, siloxane bond and ester bond. Also disclosed are a negative electrode sheet obtained by coating a current collector with a paste containing the negative electrode material, a binder and a solvent, and then drying and pressure-forming the paste; and a lithium ion battery incorporating the negative electrode sheet.
    Type: Grant
