摘要：

The use of battery electrode architectures free of support components would enable gains in device energy density. The electrochemical behavior of carbon-free electrodes with different anatase TiO2 particles is investigated. The performance is found to depend on both crystal size and morphology. Electrodes with 3 × 20 nm rods showed exceptional durability and rate capability, even when compared to electrodes with carbon additives Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
