Li4ti5o12 Anode

ABSTRACTLi4Ti5O12 (LTO) represents a promising anode material for lithium ion batteries, however, it suffers from limitations associated with poor intrinsic electron conductivity as well as moderate ionic conductivity. Hence, to achieve the goal of creating LTO anodes with improved high-rate performance, we have put forth a number of targeted fundamental strategies. Herein we discuss the roles of controllably tuning (i) morphology, (ii) attachment modalities of carbon, and (iii) ion doping of the LTO material. In addition, we also demonstrated in situ studies of lithiation-driven structural transformations in LTO via a combination of X-ray absorption spectroscopy and ab initio calculations, which have been proven to be powerful tools to probe the negligible volume change and extraordinary stability of LTO upon repeated charge/discharge cycles.
