A lithium-titanate battery is a modified lithium-ion battery that uses lithium-titanate nanocrystals, instead of carbon, on the surface of its anode. This gives the anode a surface area of about 100 square meters per gram, compared with 3 square meters per gram for carbon, allowing electrons to enter and leave the anode quickly.
Lithium titanate (Li 4 Ti 5 O 12), abbreviated as LTO, has emerged as a viable substitute for graphite-based anodes in Li-ion batteries . By employing an electrochemical redox couple that facilitates Li + ions intercalate and deintercalated at a greater potential, the drawbacks associated with graphite/carbon anodes can be overcome .
Lithium titanates are chemical compounds of lithium, titanium and oxygen. They are mixed oxides and belong to the titanates. The most important lithium titanates are: lithium titanate spinel, Li 4 Ti 5 O 12 and the related compounds up to Li 7 Ti 5 O 12. These titanates are used in lithium-titanate batteries.
Front. Mater., 09 July 2020 Lithium titanate (Li 4 Ti 5 O 12, LTO) has emerged as an alternative anode material for rechargeable lithium ion (Li +) batteries with the potential for long cycle life, superior safety, better low-temperature performance, and higher power density compared to their graphite-based counterparts.
Lithium titanate Li 4 Ti 5 O 12 attracts the researchers’ attention due to the possibility of its use in compact thin-film batteries with high stability. The formula of this compound can be more convenient represented as Li [Li 1/3 Ti 5/3]O 4.
To address these challenges, we demonstrate the potential of a lithium–lithium titanate (Li 4 Ti 5 O 12; Li–LTO) composite anode for use as an alternative to the metallic lithium anode in all-solid-state batteries.

This gives the anode a surface area of about 100 square meters per gram, compared with 3 square meters per gram for carbon, allowing electrons to enter and leave the anode quickly. Also, the redox potential of Li+ intercalation into titanium oxides is more positive than that of Li+ intercalation into graphite. This leads to fast charging (hi…
