Negative Electrode Active Material for Nonaqueous Electrolyte Secondary Batteries |
摘要 |
In order to propose a new negative electrode for nonaqueous electrolyte secondary batteries having excellent dispersibility even with a negative electrode active material having a relatively small particle size, there is proposed a negative electrode active material for nonaqueous electrolyte secondary batteries, the negative electrode active material containing silicon and having negative electrode active material particles that have a D50 based on a volume-based particle size distribution obtainable by measurement by a laser diffraction scattering type particle size distribution analysis method, of 0.1 μm to 5.0 μm, and include a surface layer containing oxygen, silicon and carbon on the entire surface or a portion of the active material surface. |
