Abstract
A method 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 at least one surface modifier present during the comminution process, the at least one surface modifier forming at least one continuous coating on at least one of the exposed surfaces 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.
