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 .
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.
Practical challenges and future directions in graphite anode summarized. Graphite has been a near-perfect and indisputable anode material in lithium-ion batteries, due to its high energy density, low embedded lithium potential, good stability, wide availability and cost-effectiveness.
After an introduction to lithium titanate oxide as anode material in battery cells, electrical and thermal characteristics are presented. For this reason, measurements were performed with two cells using different cathode active materials and a lithium titanate oxide-based anode.
A disadvantage of lithium-titanate batteries is their lower inherent voltage (2.4 V), which leads to a lower specific energy (about 30–110 Wh/kg ) than conventional lithium-ion battery technologies, which have an inherent voltage of 3.7 V. Some lithium-titanate batteries, however, have an volumetric energy density of up to 177 Wh/L.
