Patent ID: 10593933

Abstract:
Provided are a negative electrode active material for a non-aqueous electrolyte rechargeable battery, a method for preparing the same, and a non-aqueous electrolyte rechargeable battery including the same and, more specifically, a negative electrode active material for a non-aqueous electrolyte rechargeable battery, including a silicon oxide composite, capable of degrading irreversible characteristics and improving structural stability of the non-aqueous electrolyte rechargeable battery, the silicon oxide composite containing silicone, a silicon oxide represented by general formula SiOx (0<x<2), and an oxide including silicone and M (M is any one element selected from the group consisting of Mg, Li, Na, K, Ca, Sr, Ba, Ti, Zr, B, and Al), a method for preparing the same, and to a non-aqueous electrolyte rechargeable battery including the same.
