　　18650 lithium battery 3.7 v manufacturers introduce the service life and technical status of lithium titanate batteries. Lithium titanate material is used as the negative electrode material of lithium batteries. Since the industrialization of lithium-ion batteries in 1991, the negative electrode materials of batteries have been dominated by graphite. In recent years, with the development of new lithium-ion batteries, domestic and foreign researchers have conducted in-depth research on the characteristics of lithium titanate materials as anode materials for lithium batteries. Below, the 18650 lithium battery 3.7 v manufacturer introduces the service life and technical status of lithium titanate batteries.

　　After years of development in the new energy vehicle market, ternary batteries with higher energy density have gradually gained the upper hand, while lithium titanate batteries with lower energy density have gradually been marginalized by the market. The continuous decline of lithium titanate batteries in the power battery market can be traced back to the direct application of lithium titanate batteries, which do not have an advantage in energy density, to long-range passenger cars. This application mismatch also leads to Its unparalleled advantages in fast charging, lifespan, safety, etc. have been reduced to useless.

　　Lithium titanate battery life

　　Compared with graphite materials commonly used in traditional lithium-ion batteries, the skeleton structure of lithium titanate materials hardly shrinks or expands during the process of charging and discharging, inserting and desorbing lithium, avoiding the unit cell volume strain caused by general electrode materials desorbing and inserting lithium ions. The resulting problem of electrode structure damage has resulted in a huge breakthrough in lifespan. According to experimental data, the cycle life of lithium titanate batteries can reach more than 25,000 times, which is 4-8 times that of ordinary lithium batteries, and the life span can reach 30 years.

　　Lithium titanate is a "zero strain" material whose volume deformation is less than 1% during charging and discharging, giving the full battery excellent cycle performance and service life. When the lithium titanate battery product is cycled to 80% of the initial capacity under the working conditions of 25℃-100%DOD, the lifespan can reach the order of 10,000 times. Therefore, although the current manufacturing cost of lithium titanate batteries is higher than that of graphite system batteries, its super durability will greatly reduce battery maintenance and replacement costs during long-term use.

　　Lithium titanate has high stability and long life cycle, and its performance is significantly better than traditional lithium-ion batteries, giving it unique advantages in energy storage application scenarios. It is very suitable for large-scale energy storage and is called the most promising application in the industry. One of the energy storage batteries.

　　Technical status of lithium titanate batteries

　　There are not many manufacturers in the world that can mass-produce lithium titanate batteries. The application markets of lithium titanate batteries mainly include electric vehicles (buses, rail transit, etc.), energy storage markets (frequency regulation, power grid quality, wind farms, etc.) and industrial applications. (Port machinery, forklifts, etc.).

　　The main problem faced by lithium titanate batteries in large-scale application is cost. At the beginning of the project development, its price was 4-6 times that of lithium iron phosphate batteries. Although the performance is significantly better than existing lithium-ion batteries, economic factors have greatly limited the market promotion of lithium titanate batteries. Therefore, in order to realize large-scale energy storage applications of lithium titanate batteries, it is necessary to carry out technical reconstruction on the basis of existing lithium titanate batteries for electric vehicles, while ensuring the long-life intrinsic characteristics of lithium titanate batteries and significantly reducing costs. .

　　From the perspective of practical application value, lithium titanate batteries are expected to bring lower cost advantages to customers with their ultra-long cycle life. As prices become increasingly reasonable, lithium titanate is about to stage a counterattack. The future market space of lithium titanate batteries will be very limited. Coupled with the high price, compared with the high cost performance of secondary use of power batteries for energy storage in the future, titanate The future of lithium in the energy storage field is also worrying.

　　The development prospects of lithium titanate batteries in China. In the past, the main markets for lithium batteries were portable appliances, mobile phones, laptops, etc. For future development prospects, the current key to improving the energy density of lithium titanate batteries is the development of high-capacity, high-potential solutions and antioxidant separators. China's 18650 lithium battery 3.7 v industry's efforts to develop lithium titanate battery technology will be rewarded handsomely by the rising electric vehicle, energy storage and industrial application markets.

　　Although lithium titanate batteries do not have an advantage in energy density, with their unparalleled advantages in fast charging, safety and lifespan, through differentiated competition, they can be used in fields that require high charging speed and frequency. To win a place, Power Company will continue to develop in-depth lithium titanate fast-charging battery technology, continue to explore its performance limits and application potential, and bring customers a more superior and convenient use experience.
