  • Precharged negative electrode material for secondary battery
    Patent number: 11637280
    Abstract: Provided are methods of producing a negative electrode including comminuting Li-Group IVA alloy particles in a solvent to a desired particle size distribution range, exposing surfaces of the Li-Group IVA alloy particles to a monomer or polymer surface modifier present during the comminution process, the surface modifier forming a continuous coating on an exposed surface of the Li-Group IVA alloy particles, removing the solvent, and adding the surface-modified Li-Group IVA alloy particles to a negative electrode material by a coating process.
    Type: Grant
