Anatase TiO as a Cheap and Sustainable Buffering Filler for Silicon Nanoparticles in Lithium-Ion Battery Anodes.

The design of effective supporting matrices to efficiently cycle Si nanoparticles is often difficult to achieve and requires complex preparation strategies. In this work, we present a simple synthesis of low-cost and environmentally benign aAnatase TiO nanoparticles as buffering filler for Si nanoparticles (Si@TiO ). The average anatase TiO crystallite size was approximately 5 nm.
