Features of lithium titanate battery technology Lithium - Ion Battery Equipment

What are the advantages and disadvantages of lithium titanate battery technology

Lithium titanate battery has the advantages of small size, light weight, high energy density, good sealing performance, no leakage, no memory effect, low self-discharge rate, rapid charge and discharge, long cycle life, wide working environment temperature range, safe and stable green It has the characteristics of environmental protection and so on, so it has a very wide application prospect in the field of communication power supply.

When the lithium titanate battery is used as the negative electrode material, the potential platform is as high as 1.55V, which is more than 1V higher than that of the traditional graphite negative electrode material. Although some energy density is lost, it also means that the battery is safer.(Lithium - Ion Battery Equipment)

Because the lithium titanate battery can be used safely in both high temperature and low temperature environments, it also reflects its important advantages of wide temperature resistance (especially low temperature resistance). At present, the safe operating temperature range of Yinlong lithium titanate battery is between -50 degrees and 65 degrees.

Long cycle life. Compared with the graphite materials commonly used in traditional lithium ion batteries, the skeleton structure of lithium titanate battery materials hardly shrinks or expands during the charging and discharging process of intercalation and delithiation. / The problem of damage to the electrode structure caused by the volumetric strain of the unit cell when intercalating lithium ions.

The last advantage of lithium titanate batteries is their fast charge and discharge capability and high charge rate. At present, the charging rate of Yinlong lithium titanate battery is 10C or even 20C, while the charging rate of ordinary graphite anode material is only 2C-4C.

Lithium titanate ion batteries will continue to produce gas in the cycle of use, causing the battery pack to swell, especially at high temperatures, affecting the contact between the positive and negative electrodes, increasing the battery impedance, and affecting the performance of the battery. This is also one of the important obstacles that limit the wide application of lithium titanate as an anode material in batteries.

The process of nanometerization of lithium titanate battery material particles is often difficult and requires high cost, and it is currently difficult to achieve large-scale industrial production.
