Negative electrode active material, mixed negative electrode active material, negative electrode for nonaqueous electrolyte secondary battery, lithium ion secondary battery, and, production method of negative electrode active material |
abstract |
A negative electrode active material includes particles of negative electrode active material, wherein the particles of negative electrode active material contain particles of silicon compound containing silicon compound (SiO x :0.5≤x≤1.6), the particles of negative electrode active material contain crystalline Li 2 SiO 3 in at least a part thereof, and the particles of negative electrode active material satisfy the following formula 1 and formula 2 between an intensity A of a peak derived from Li 2 SiO 3 , an intensity B of a peak derived from Si, an intensity C of a peak derived from Li 2 Si 2 O 5 , and an intensity D of a peak derived from SiO 2 , which are obtained from a 29 Si-MAS-NMR spectrum. Thus a negative electrode active material capable of increasing a battery capacity, and improving the cycle characteristics and initial charge/discharge characteristics when used as a negative electrode active material of the lithium ion secondary battery is provided.n nA>B>D (1)n nA>C>D (2) |
