- 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.
