Electrochemical properties of the TiO 2 (B) powders ball mill

2013/11/06Belt or wire shaped TiO2(B) particles were synthesized for lithium ion battery application by a hydrothermal and heat treatment process. In order to facilitate TiO2(B)/C composites fabrication, the synthesized TiO2(B) particles were crushed into smaller sizes by ball milling. Ball mill treated TiO2(B) particles of less than 1.0 μm with a fraction of anatase phase, compared to as-synthesized
