Polysilsesquioxane covered silicon nanoparticles or calcined product thereof and production method thereof, negative electrode active material for lithium ion battery, negative electrode for lithium ion battery and lithium ion battery
Polysilsesquioxane covering silicon nanoparticles, or a calcined product thereof, comprising silicon nanoparticles, which have a volume-basis mean particle size of 10-500 nm, exclusive, and do not include particles having a particle size of 1000 nm or larger, and polysilsesquioxane, which covers the silicon nanoparticles and is chemically bonded to the surfaces of the silicon nanoparticles, said polysilsesquioxane covering silicon nanoparticles or the calcined product thereof having Si—H bonds. When observed using a transmission electron microscope (TEM), the thickness of the polysilsesquioxane is 1-30 nm, inclusive.
