Advantages of power batteries.LR1130 battery

　　Today, with the global focus on developing new energy industries such as electric vehicles and energy storage batteries, lithium batteries have received higher attention as widely recognized aspiring energy storage components. China has also invested huge funds and policy support in the field of power batteries, and has now emerged as a globally recognized backbone enterprise in the battery industry, including BYD, BYC, Lishen, and AVIC Lithium Battery. Battery barrier and electrolyte are four very important raw materials for lithium batteries. Due to the high risk of investment and technical barriers, lithium battery barrier has not been able to achieve large-scale production in China, becoming a bottleneck that restricts the development of lithium battery industry in China. Especially in the field of power lithium-ion batteries with higher requirements for safety and consistency, it is an obstacle that China cannot overcome from a major producer of lithium batteries to a strong producer of lithium batteries.

　　Power battery manufacturers analyze that the primary production processes for lithium battery barriers can be divided into two categories: dry process and wet process. The vehicle power battery has a large capacity and high safety requirements, which also require the barrier to have higher strength, liquid retention ability, and safe temperature. The dry process can adopt a multi-layer composite form, which has many advantages such as structural safety, uniform pores, good breathability, and high temperature resistance. It fully meets the strict requirements of power lithium batteries. Many power battery manufacturers at home and abroad recognize the barrier of this process as the application direction of power lithium batteries.

　　The global lithium battery production capacity is rapidly expanding, and as the primary material, the growth rate of lithium battery barrier production capacity has lagged behind. Currently, many battery manufacturers have expressed varying degrees of gap and shortage. The progress of barrier production capacity is not only an urgent requirement for the development of China's lithium battery industry and even the international lithium battery industry. Therefore, the rapid emergence of more ethnic enterprises with the same material as Star Source in China is an important measure to improve the professional industry chain of lithium batteries in China, enhance the competitiveness and sustainable development ability of lithium battery production enterprises, and is also a key link related to the rapid development of China's new energy vehicle industry

　　1. The cycle life of lead-acid battery with super long life and long life is about 300 times, and the very high cycle life is 500 times. The Lithium iron phosphate power battery produced should have a cycle life of more than 2000 times, and the standard charging (5 hour rate) can be used for 2000 times. Lead acid batteries of the same quality are "new half year, old half year, protection and protection half year", many of which are only 1 to 1.5 years old, while Lithium iron phosphate battery will be used for 7 to 8 years under the same conditions. Overall, the cost performance ratio will be more than 4 times that of lead-acid batteries

　　2. Safe operation, Lithium iron phosphate has completely solved the potential safety problems of lithium cobalate and lithium manganate. Lithium cobalate and lithium manganate will explode under fierce collision, posing a threat to the life safety of customers, while Lithium iron phosphate will not explode even in very bad traffic accidents after passing the strict safety test.

　　3. It can quickly charge and discharge at a high current of 2C. Under a dedicated charger, the battery can be fully charged within 40 minutes at 1.5C, and the starting current can reach 2C. However, lead-acid batteries do not have this performance.

　　4. High temperature resistance, the peak value of Lithium iron phosphate electric heating can reach 350 ℃~500 ℃, while lithium manganate and lithium cobalate are only about 200 ℃.

　　5. Large capacity.
