摘要
(Graph Presented) Surprising anode material! A mesoporous anatase was synthesized that showed superior rate capability. Even after 1000 charge/discharge cycles at a rate of 12000 mAg-1 (1.6 min per cycle), the mesostructure was retained with a stable capacity of 125 mA h g -1 (see diagram). © 2010 Wiley-VCH Verlag GmbH & Co.
