This review highlights breakthroughs in the past decade in the synthesis and the modification of both the chemistry and morphology of Li 4Ti 5O 12.
Lithium-ion batteries are considered as one of the most promising power sources for energy storage system for a wide variety of applications such as electric vehicles (EVs) or hybrid electric vehicles (HEVs). The anode material often plays an important role in the determination of the safety and cycling life of lithium-ion batteries. Among all anode materials, spinel Li 4Ti 5O 12 has been considered as one the most promising anode candidates for the next-generation large-scale power lithium-ion batteries used for HEVs or EVs because it has a high potential of around 1.55 V ( vs. Li/Li +) during charge and discharge, excellent cycle life due to the negligible volume change, and high thermal stability and safety. In this review, we present an overview of the breakthroughs in the past decade in the synthesis and modification of both the chemistry and morphology of Li 4Ti 5O 12. An insight into the future research and further development of Li 4Ti 5O 12 composites is also discussed.
