Negative electrode active material for nonaqueous electrolyte secondary battery and method for producing same |
abstract |
The present invention is a negative electrode active material for a non-aqueous electrolyte secondary battery, containing negative electrode active material particles. The negative electrode active material particles include silicon compound particles each containing a silicon compound (SiO X : 0.5≤X≤1.6). The silicon compound particle contains at least one or more of amorphous silicon and microcrystalline silicon. The negative electrode active material particles each contain at least one or more of Li 2 SiO 3 and Li 2 Si 2 O 5 as a Li compound. The negative electrode active material particle contains a compound having a zeolite crystal structure, the compound adhering to a surface layer portion of the negative electrode active material particle. This provides a negative electrode active material having high stability in an aqueous slurry, high capacity, and favorable cycle characteristics and first-time efficiency. |
