Challenges of Spinel Li4Ti5O12 for Lithium‐Ion Battery Industrial Applications

Rechargeable lithium‐ion batteries (LIBs) offer the advantages of having great electrical energy storage and increased continuous and pulsed power output capabilities, which enable their applications in grid energy storage and electric vehicles (EVs). For safety, high power and durability considerations, spinel Li4Ti5O12 is one of the most appealing potential candidate as an anode material for power LIBs due to its excellent cycling stability and thermal stability. However, there are still a number of challenges remaining for Li4Ti5O12 battery applications. Herein, an updated overview of the latest advances in Li4Ti5O12 research is provided and key challenges for its future development (i.e., fast‐charging, specific capacity, swelling, interface chemistry, matching cathode and electrolyte as well as batteries design and manufacturing) are highlighted. Spinel Li4Ti5O12 is one of the most appealing potential candidate anode materials for power lithium‐ion batteries due to its excellent cycling and thermal stability. An updated overview of three key industrial application challenges of Li4Ti5O12 (fast‐charging, swelling issues and relatively low energy density) and the latest advances in Li4Ti5O12 research for its future development is provided.
