Advantages of lithium titanate batteries
The adoption of electric vehicles to replace fuel vehicles is the best choice to solve urban environmental pollution, among which lithium ion power battery has
attracted extensive attention of researchers.
At present, the cathode of commercial lithium ion battery mainly USES carbon material, but there are still some disadvantages in the application of the cathode
of carbon lithium battery:
1. Lithium dendrites are easy to precipitate out during overcharging, resulting in short circuit of the battery and affecting the safety performance of the lithium battery;
2. It is easy to form SEI, which leads to low efficiency and large irreversible capacity of the first charge and discharge;
3. That is, the platform voltage of carbon material is low (close to lithium metal), and it is easy to cause the decomposition of electrolyte, thus bringing safety risks.
4. In the process of lithium ion embedding and ejection, the volume changes greatly and the cycling stability is poor.
Compared with carbon materials, spinel type Li4Ti5012 has obvious advantages:
1. It is a zero-strain material with good cycling performance;
2, the discharge voltage is stable, and the electrolyte will not decompose, improve the safety of lithium battery;
3. Compared with carbon anode materials, lithium titanate has a high diffusion coefficient of lithium ion (2*10-8cm2/s) and can charge and discharge 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 dendrites, which provides a foundation for the safety of lithium batteries.
