Lithium-ion batteries (LIBs) have become popular electrochemical devices. Due to the
unique advantages of LIBs in terms of high operating voltage, high energy density, low
self-discharge, and absence of memory effects, their application range, which was primarily
restricted to portable electronic devices, is now being extended to high-power applications,
such as electric vehicles (EVs) and hybrid electrical vehicles (HEVs). Among various anode
materials, Li4Ti5O12 (LTO) is believed to be a promising anode material for high-power LIBs
due to its advantages of high working potential and outstanding cyclic stability. However,
the rate performance of LTO is limited by its intrinsically low electronic conductivity and
poor Li+ ion diffusion coefficient. This review highlights the recent progress in improving
the rate performance of LTO through doping, compositing, and nanostructuring strategies.
