What are the advantages of the eight major advantages of lithium iron phosphate battery?

　　1. Improve safety performance

　　The P-O key in lithium iron phosphate crystals is stable and difficult to decompose. Even when it is high or overcharge, it will not be structurally like lithium cobaltate or forms a strong oxidized substance, so it has good safety.

　　Some reports pointed out that in the actual operation, a small number of samples were found in acupuncture or short -circuit experiments, but there was no explosion event, and the use of high voltage charging was greatly exceeded in the over -charging experiment. Explosion.

　　Nonetheless, its overload safety has greatly improved compared to ordinary liquid electrolytic lithium cobaltate batteries.

　　2. Improve life

　　Lithium iron phosphate batteries refer to lithium ion batteries using lithium iron phosphate as a positive pole material.

　　The circulation life of long life lead -acid batteries is about 300 times, and the maximum is 500 times. The cycle life of lithium iron phosphate power batteries has reached more than 2,000 times. The standard charging (5 -hour rate) can be used for 2000 times. The same -quality lead -acid batteries are "new half a year, old half a year, maintenance and maintenance for half a year", and it is only 1 to 1.5 years, and the lithium iron phosphate battery will be used under the same conditions, and the theoretical life span will reach 7-8 years.

　　In comprehensive consideration, the performance price is more than 4 times theoretically more than 4 times the lead -acid battery. Large current discharge can be large -current 2C quickly charged and discharged. Under a special charger, the battery can be fully charged within 40 minutes. 2C, the lead -acid battery has no performance.

　　3. Good high temperature performance

　　Lithium iron phosphate can reach 350 ° C-500 ° C, and lithium manganate and lithium cobaltate can only be around 200 ° C. The working temperature range is wide (-20C-+75C). 350 ° C-500 ° C, while lithium manganate and lithium cobaltate are only about 200 ° C.

　　4. Large capacity

　　It has a larger capacity than ordinary batteries (lead acid, etc.). The single capacity is 5AH-1000AH.

　　5. No memory effect

　　The battery can work under the condition that it is often filled with unstoppable conditions, and the capacity will be quickly lower than the rated capacity value. This phenomenon is called memory effect. Like nickel -metal hydride and nickel -cadmium batteries, there are memory, while lithium iron phosphate batteries do not have this phenomenon. No matter what state in the battery is, it can be used with it without charging before charging.

　　6. Light weight

　　The volume of the lithium iron phosphate battery of the same specifications is 2/3 of the volume of the lead -acid battery, and the weight is 1/3 of the lead -acid battery.

　　7. Environmental protection

　　The battery is generally considered to be no heavy metal and rare metals (nickel -metal hydride batteries require rare metals), non -toxic (SGS certification), non -polluting, and complies with European ROHS regulations to be an absolute green environmental protection battery certificate.

　　Therefore, the reason why lithium batteries are optimistic about the industry are mainly environmental protection considerations. Therefore, the battery is also included in the "863" national high -tech development plan during the "Fifth Fifteenth" period, becoming a project for national key support and encouraging development.

　　8. Comparison of power batteries

　　At present, the positive electrode materials that are hoped to be applied to the power lithium ion battery are mainly modified lithium manganate (LIMN2O4), lithium iron phosphate (LIFEPO4), and nickel cobalt lithium manganate (Li (Ni, Co, Mn) O2) ternary ternary Material.

　　Nickel cobalt lithium manganate Trichousing materials Due to the lack of cobalt resources, such as nickel, cobalt high and price fluctuations, etc., it is generally believed that it is difficult to become the mainstream of electric vehicle power -type lithium ion batteries, but it can be with spinel manganate. Lithium is mixed within a certain range.
