TiO2 anode materials for lithium-ion batteries with different morphology and additives

Electrochemical performances of different TiO 2 nanostructures, TiO 2 /CNT composite and TiO 2 with titanium isopropoxide (TTIP) treatment anode were investigated. For different TiO 2 nanostructures, we investigated vertically aligned TiO 2 nanotubes on Ti foil and TiO 2 nanotube-powders fabricated by rapid breakdown anodization technique. The morphology of the prepared samples was characterized by scanning probe microscopy (SEM). The electrochemical lithium storage abilities were studied by galvanostatic method. In addition, carbon nanotubes (CNT) additives and solution treatment process of TiO 2 anode were investigated, and the results show that the additives and treatment could enhance the cycling performance of the TiO 2 anode on lithium ion batteries.
