Advantages of lithium titanate battery
The use of electric vehicles instead of fuel vehicles is the best choice for solving urban environmental pollution. Among them, lithium-ion power batteries have attracted wide attention of researchers. In order to meet the requirements of electric vehicles for on-board neodymium ion batteries, high safety and high rate performance have been developed. And the long-life anode material is a hot spot and a difficult point.
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.
