Direct Access to Mesoporous Crystalline TiO 2 /Carbon Composites with Large and Uniform Pores for Use as Anode Materials in Lithium Ion Batteries

Mesoporous and highly crystalline TiO 2 (anatase)/carbon composites with large (>5 nm) and uniform pores were synthesized using PI‐ b ‐PEO block copolymers as structure directing agents. Pore sizes could be tuned by utilizing block copolymers with different molecular weights. The resulting mesoporous TiO 2 /carbon was successfully used as an anode material for Li ion batteries. Without addition of conducting aid (Super P), the electrode showed high capacity during the first insertion/desertion cycle due to carbon wiring inside the walls of mesoporous TiO 2 /carbon. The electrode further showed stable cycle performance up to 50 cycles and the specific charge capacity at 30 C was 38 mA h (g of TiO 2 ) −1 , which indicates CCM‐TiO 2 /carbon can be used as a material for high rate use.
