What are the advantages and disadvantages of lithium titanate Battery 

(LTO) anode materials?



Lithium titanate is an inorganic compound with the molecular formula of Li4Ti5O12, which has the appearance of white powder, melting point 1520~1564íŠ, insoluble in water and has strong fluxing properties. The spinel structure of lithium titanate is considered as one of the most promising materials for lithium-ion battery anode due to its high cycle life and safety characteristics.

The new lithium titanate is a "zero-tension" material, so that the LTO battery life is greatly extended, charging and discharging cycles can reach thousands of times or more. At present, the newly developed lithium titanate cathode material and lithium manganate cathode material have been applied to the green lighting system of scenery complementary environment.

The advantages of lithium titanate Battery cathode material


1, lithium titanate cathode material has small volume, light weight, high energy density, good sealing performance, no leakage, no memory effect, low self-discharge rate, rapid charging and discharging, long cycle life, wide operating temperature range, safe and stable, green and other characteristics, so in the field of communication power has a very wide application prospects.

2, lithium titanate batteries can be used safely in high and low temperature environments, and the life of Yinlong lithium titanate materials can reach 30 years, which is comparable to the service life of automobiles, while the average life of ordinary graphite negative electrode material batteries is only 3-4 years. From the whole life cycle, the cost of lithium titanate battery is lower.

3, fast charging and discharging ability, high charging multiplier.

The last advantage of lithium titanate materials is the strong ability of rapid charge and discharge, high charging rate. At present, the charging rate of lithium titanate battery is 10C, or even 20C, while the charging rate of ordinary graphite anode material is only 2C-4C.

The disadvantages of lithium titanate cathode material


1, lithium battery life, performance, etc. is affected by a number of aspects, especially the impact of the four major materials. Lithium titanate is only the negative electrode material, a material and then how to progress, it is difficult to make the product unbeatable advantage. Not to mention that the anode material is the most important material affecting the performance of lithium batteries.

2, lithium titanate battery energy density is low, the cost is high. In particular, the low energy density is due to the principle performance of the negative electrode material lithium titanate decision, it is difficult to have a large breakthrough space. Cost can be reduced through scale, and based on the principle of weakness, can not be changed through technology.

3, as for the long service life claimed by lithium titanate battery, it is more difficult to be certified. Battery life is also affected by a combination of cathode materials, electrolyte, diaphragm, temperature and so on. Lithium titanate to do the negative electrode, there is also flatulence and long-term use of consistency reduction and other issues, the current principle can not prove that lithium titanate battery will be longer than other battery life.

4, do lithium titanate materials to do less enterprises, resulting in less overall industry investment in research and development, from the current battery business R & D investment and planning investment, few companies will focus on the development of lithium titanate. In the future, other lithium battery technology will progress faster than lithium titanate.

Lithium titanate battery cathode material has the characteristics of small size, light weight, high energy density, good sealing performance, no leakage, no memory effect, low self-discharge rate, rapid charging and discharging, long cycle life, wide operating temperature range, safe and stable, green and environmental protection, so it has a very wide range of application prospects in the field of communication power.
