Lithium Titanate Battery — Top Rated 33.5Ah Secondary Li Ion Battery Pack

From:CTECHI GROUP Limited     Release time:2019-01-16

Overview:Lithium titanate battery is a kind of lithium-ion battery negative material - lithium titanate, which can be used as lithium manganate, ternary materials or lithium iron phosphate positive material to form 2.4V or 1.9V lithium-ion secondary battery. In addition, it can also be used as a cathode for 1.5V lithium secondary batteries with metal lithium or lithium alloy negative electrodes. Because of the high safety, high stability, long life and environmental protection of lithium titanate.

I. What is Lithium Titanate Battery


Lithium titanate battery is a kind of lithium-ion battery negative material - lithium titanate, which can be used as lithium manganate, ternary materials or lithium iron phosphate positive material to form 2.4V or 1.9V lithium-ion secondary battery. In addition, it can also be used as a cathode for 1.5V lithium secondary batteries with metal lithium or lithium alloy negative electrodes. Because of the high safety, high stability, long life and environmental protection of lithium titanate.


II. Composition of Lithium Titanate Batteries


Negative electrode: lithium titanate material.

Diaphragm: Lithium battery diaphragm with carbon as negative electrode.

Electrolyte: Lithium battery electrolyte with carbon as negative electrode.

Battery case: Lithium battery case with carbon as negative electrode.

Ⅲ. Advantages and disadvantages of lithium titanate batteries:


1. Good safety and stability


Once the traditional carbon electrode is overcharged after lithium intercalation, the metal lithium is easily precipitated on the surface of the electrode. The reaction between the carbon electrode and the electrolyte will produce flammable gas, which brings about potential safety hazards. The potential of lithium titanate is higher than that of pure metal lithium. It is not easy to produce lithium dendrites, and the discharge voltage is stable. Moreover, the safety performance of lithium batteries is improved. Third-party organizations have tested lithium titanate batteries and found that under the rigorous tests of needling, extrusion and short circuit, the safety of lithium titanate batteries is much higher than that of other lithium batteries without smoking, fire or explosion. Therefore, many people in the industry believe that lithium titanate is very suitable for use in the field of military industry which requires very high stability of batteries.


2. Excellent fast charging performance


Compared with carbon anode materials, lithium titanate has a higher lithium ion diffusion coefficient and can charge and discharge at a higher rate. While greatly shortening the charging time, it has little effect on the cycle life and strong thermal stability. According to the test, lithium titanate batteries developed by the latest technology can be filled in about ten minutes, which is a qualitative leap over traditional batteries.


Long charging time has always been an obstacle in the development of electric vehicles. Generally, slow-charging pure electric buses take at least 4 hours to charge, and many pure electric passenger buses take up to 8 hours to charge. Fast charging of electric vehicles is the trend of the future. Consumers are unwilling to waste too much time waiting for charging.


3. Long cycle life


Battery cycle life determines the performance-price ratio of the whole new energy vehicle, and it is the main competitive point of the future new energy vehicle after it breaks away from the subsidy policy. The prolonged cycle life of automotive batteries enables consumers to afford and sustain them.


4. Good resistance to wide temperature


The spinel structure of lithium titanate batteries has three-dimensional lithium ion diffusion channels, so the performance of lithium titanate batteries at high and low temperatures is also excellent. Generally, the charging and discharging of electric vehicles will occur at minus 10 C. Lithium titanate batteries have good wide temperature resistance and durability. They can charge and discharged normally from minus 50 C to minus 60 C. Whether in the frozen north or in the hot south, the vehicles will not be affected by the "shock" of batteries, eliminating the worries of users.


Ⅳ. Disadvantages:

1. Compared with other types of lithium-ion power batteries, the energy density will be lower.

2. The problem of gas expansion has been hindering the application of lithium titanate batteries.

3. Compared with other types of lithium-ion power batteries, the price is on the high side.

4. There are still differences in battery consistency, which will increase with the increase of charging and discharging times.
