Description

Lithium Titanate (LTO) Battery 22,000 cycles 48V 40Ah 1.9 kWh
We have a total 4 available!  Key benefits of an LTO battery!\:
• High power
charge and discharge capacity: fast charge takes only 6 minutes.
• Long cycle life: 10 times that of traditional lithium-ion batteries.
• Low temperature charge and discharge performance: low temperature -30 ° C good condition.
• Good safety performance. The lithium titanate negative electrode has almost no SEI film, thereby      avoiding the battery from overheating and causing a fire.
• Lithium titanate battery has the characteristics of long life, good low temperature performance, safe and fast charging and discharging, and can be applied to the storage of peaks and valleys, wind energy and solar energy.

Negative electrode: lithium titanate material.
Diaphragm: A lithium battery separator that uses carbon as a negative electrode.
Electrolyte: A lithium battery electrolyte using carbon as a negative electrode.
Battery case: A lithium battery case that uses carbon as a negative electrode.
Advantages of lithium titanate battery
At present, commercial lithium-ion battery anodes mainly use carbon materials, but lithium batteries with carbon as anodes still have some drawbacks in application:
1. Lithium dendrites are easily precipitated during overcharging, causing short circuit of the battery and affecting the safety performance of the lithium battery;
2. Easy to form SEI film, resulting in lower initial charge and discharge efficiency, irreversible capacity;
3. The platform voltage of the carbon material is low (close to metallic lithium), and it is easy to cause decomposition of the electrolyte, thereby posing a safety hazard.
4. The volume change is large during the process of lithium ion insertion and extraction, and the cycle stability is poor.
Compared to carbon materials, the spinel-type Li4Ti5012 has obvious advantages:
1. It is a zero strain material with good cycle performance;
2. The discharge voltage is stable, and the electrolyte does not decompose, improving the safety performance of the lithium battery;
3. Compared with the carbon anode material, lithium titanate has a high lithium ion diffusion coefficient (2*10-8 cm2/s), and can be charged and discharged at a high rate.
4. The potential of lithium titanate is higher than that of pure metal lithium, which is not easy to produce lithium crystal branches, which provides a basis for ensuring the safety of lithium batteries
