Negative electrode active material for lithium-ion secondary cell |
| abstract |
I G / I D (G value) is 5.2 or less than 100, and the area and the aspect ratio is 50% the diameter of the optical tissue (D 50) [㎛] 1.5≤A OP ≤6 and 0.2 × D 50 ≤ with respect to (S OP × a OP) 1/2 <2 × D 50 and relationship scale graphite carbon material (a) on which satisfy the, surface layer is formed of a SiO x (0 <x≤2), the oxygen content of 1 mass Silicon-containing particles (b2) having a primary particle size of 200 nm or less and a primary particle size of 200 nm or less and 90% or more (by number basis) of carbon nanotubes having an aspect ratio of 100 to 1000 are dispersed in an aggregate of carbon nanotubes , And a carbonaceous carbon material (C) covering at least a part of a surface of the silicon-containing particles (b2), and a negative electrode active material for a lithium ion secondary battery. |
