Challenges of Spinel Li₄Ti₅O₁₂ for Lithium‐Ion Battery Industrial Applications

Abstract

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 Li 4 Ti 5 O 12 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 Li 4 Ti 5 O 12 battery applications. Herein, an updated overview of the latest advances in Li 4 Ti 5 O 12 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.
