Recent Development in the Rate Performance of Li<sub>4</sub>Ti<sub>5</sub>O<sub>12</sub>
Lin, Chunfu,Xin, Yuelong,Cheng, Fuquan,Lai, Man On,Zhou, Henghui,Lu, Li The Korean Vacuum Society 2014 Applied Science and Convergence Technology Vol.23 No.2
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, $Li_4Ti_5O_{12}$ (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.
