Lithium titanate (LTO) short-circuit characteristics

The new technology using lithium titanate (LTO) is drawing attention as new anode material. Compared with other lithium cell materials, LTO has superior thermal stability. Furthermore, unlike carbon, the titanate oxide, a component of LTO, is non-conductive. For the lithium-ion batteries employing carbon material, when an internal short circuit occurs, electric current passes through the anode at a burst, which leads to abnormal heating.

On the contrary, for the lithium-ion batteries with LTO, when an internal short circuit happens, there is no burst of electric current on the anode. So, the exothermic reaction of the anode is moderate.

Lithium Titanate batteries for mobile energy also offer the advantage in that they are able to store and deliver a current that is between 30 and 100 times that of regular Li-ion batteries.
