Abstract
A negative electrode material containing a negative electrode active material particle which includes a silicon compound particle containing a silicon compound (SiO: 0.5≤x≤1.6). The silicon compound particle contains at least one or more of LiSiOand LiSiO, and the negative electrode material further contains at least one of a metal compound particle containing a metal compound and an aggregate of the metal compound particle. The negative electrode material is capable of stabilizing a slurry prepared in production of a negative electrode for a secondary battery, and improving initial charge-discharge characteristics and cycle characteristics when it is used as a negative electrode active material for a secondary battery.
