Tailoring nanostructured TiO 2 for high power Li-ion batteries
Abstract
It is shown that the rate performance of anatase TiO 2 can be significantly improved by addition of a small amount (few percent) of carefully selected oxides such as silica or RuO 2. Specifically, silica serves primarily as a suppressant of particle growth during heating of anatase precursor-in our case titania nanotubes. The addition of RuO 2 is supposed to enhance the electronic conductivity. The beneficial impact of the combined use of silica and RuO 2 in the preparation of anatase-based electrodes is also demonstrated on a commercially available sample of anatase.
