Silicon nanoparticle-containing hydrogen polysilsesquioxane calcined product-metal oxide complex and production method thereof, negative electrode active material for lithium ion battery, negative electrode for the lithium ion battery and lithium ion battery
A silicon nanoparticle-containing hydrogen polysilsesquioxane sintered product-metal oxide complex comprising a silicon nanoparticle-containing hydrogen polysilsesquioxane sintered product and a metal oxide, wherein the silicon nanoparticle-containing hydrogen polysilsesquioxane sintered product contains 5 wt % to 95 wt % of silicon nanoparticles having a volume-based mean particle size of more than 10 nm but less than 500 nm, and a hydrogen polysilsesquioxane-derived silicon oxide structure that coats the silicon nanoparticles and is chemically bonded to the surfaces of the silicon nanoparticles. The silicon nanoparticle-containing hydrogen polysilsesquioxane sintered product is represented by the general formula SiOxHy (0.01<x<1.35, 0<y<0.35) and has Si—H bonds. The metal oxide consists of one or more metals selected from titanium, zinc, zirconium, aluminum, and iron.
