Nanoparticulate TiO2(B): An Anode for Lithium‐Ion Batteries

Small but powerful: TiO2(B) with the smallest particle size yet reported (2.5×4.3 nm) has been synthesized (see TEM image). Its volumetric capacity to store lithium, and hence charge, as an anode in a lithium-ion battery is greater than that of any other titanate at high rates (>1000 mA g−1).
