What are the advantages and disadvantages of lithium titanate batteries?

Advantages of lithium titanate batteries 1. Good safety: The most important point of electric vehicle batteries is to have high safety. Because of its high equilibrium potential, lithium titanate does not form lithium dendrites on the negative electrode, and has good safety. 2. Good cycle performance: Because it is a zero-strain material, it will not undergo structural changes during charging and discharging, and has excellent cycle performance. 3. It can be charged and discharged quickly: the diffusion coefficient of lithium ions in lithium titanate crystals is 2u0026TImes;10-8cm-2/s, which is an order of magnitude more than that of the graphite negative electrode. It can be charged and discharged quickly. The fast charging ability is for investigating electric vehicle batteries. An important indicator. 4. The working temperature range is -30℃~60℃: the insertion and extraction capacity of lithium will decrease at low temperature, especially the insertion capacity. The lithium titanate negative electrode will not cause short circuit or deteriorate the negative electrode when it is charged at -30℃. Lithium dendrites appear, which is impossible for graphite anodes. They can be quickly charged and discharged in a wide range of environments, and are suitable for automotive applications. 5. Low self-discharge: the battery adopts conventional lithium manganate for the positive electrode and lithium titanate for the negative electrode. The capacity remaining rate for 28 days of storage at 60 degrees is 88%, and the capacity recovery rate is over 95%. Disadvantages of lithium titanate batteries 1. Compared with other types of lithium-ion power lithium-ion batteries, the energy density will be lower. 2. The problem of flatulence has been hindering the application of lithium titanate batteries. 3. Compared with other types of lithium-ion power lithium-ion batteries, the price is relatively high.
