Active material for non-aqueous electrolyte secondary battery, negative electrode molded body, and non-aqueous electrolyte secondary battery |
abstract |
The present invention provides an active material comprising silica-attached particles in the form of host particles of silicon or a silicon compound having spherical silica nanoparticles attached to the surface thereof, suitable for use in non-aqueous electrolyte secondary batteries. The spherical silica nanoparticles have an average particle size of 5-1000 nm, a particle size distribution D 90 /D 10 of 3 or less, and an average circularity of 0.8-1. The active material has high fluidity and shows improved cycle performance when used in a non-aqueous electrolyte secondary battery. |
