Lithium Titanate LTO-100
Introduction:
Lithium Titanate is a compound containing lithium and titanium. It is an off-white powder at room temperature and has the chemical formula Li4Ti5O12. LTO-100 is a spinel type lithium titanate made based on titanium dioxide, with stable crystal structure and three-dimensional ion exchange channel. It is the anode component (-) of the fast charging lithium-titanate battery. It is also used as an additive in porcelain enamels and ceramic insulating bodies based on titanates.

Special Features:
● LTO-100 is produced one step by chemical synthesis under mild conditions, quality is stable and consistent.
● It is a zero strain material, hardly changed during charge and discharge, with excellent cycling performance.
● With an ion diffusion rate higher than that of a carbon negative electrode by a magnitude level, it can be charged quickly.
● Discharge voltage is stable, and electrolyte does not decompose, improve the safety performance of lithium battery.
● It has high diffusion coefficient of lithium ion (2*10-8cm2/s), and can be charged and discharged at high rate.
● Lithium titanate has high electric potential and hardly to generate lithium dendrites, which ensures the safety of lithium battery.
