The positive electrode of the lithium-ion battery is the lithium iron phosphate material, which has good performance in safe operation and life cycle. It is one of the most important measurements of battery power. Lifepo4 battery with 1C charge and discharge cycle life can be reached 2000 times, it will not crack or explode, and will not burn or crack easily when overcharged. The lithium metal phosphate anode material facilitates the serial use of large capacity lithium-ion batteries.
Lithium iron phosphate as anode material
Lifepo4 battery refers to a lithium-ion battery that uses lithium metal phosphate as the anode material. The cathode materials of lithium-ion batteries generally include lithium cobaltate, lithium manganate, lithium nickelate, ternary materials, lithium iron phosphate, etc. Among them, lithium cobaltate is the cathode material used in most lithium-ion batteries. Generally, lithium iron phosphate is also a waste and desorption process. This principle is the same as that of lithium cobaltate and lithium manganate.

lifepo4 battery quality
1. High salary and dismissal
The Lifepo4 battery is a second lithium-ion battery. An important focus is battery power. It has the best combination of NI-MH and Ni-Cd batteries. Lifepo4 battery has high charge and discharge performance, and in the discharge situation, the charge and discharge can reach more than 90%, when the lead -acid is about 80%.
2. The lifepo4 battery has good security
The PO bond of lithium iron phosphate crystals is stable and difficult to decompose, does not crack or heat up like lithium cobaltate, and does not produce strong oxidizing chemicals even under high temperature or under overload, which gives it very good security.
lifepo4 battery and apps
In actual operation, the flames were found in part of the model when testing for needle or short circuit, but it was reported that there was no crack. In the overcharge test, a high voltage charge several times higher than the self-discharge voltage was used, but it was found that there was still a breakdown effect. However, the overcharge safety was better compared to ordinary liquid electrolyte lithium-cobalt oxide.
3. Lifepo4 battery life is long
Lifepo4 batteries are lithium-ion batteries that use lithium metal phosphate as the cathode material.
The life cycle of long-life lead-acid is about 300 times, and the maximum is 500 times. Lithium iron phosphate powered batteries have a life of over 2000 cycles, with a standard charge (5 hours) up to 2000 cycles.
Lead acid batteries are similar to “half new, half year, half year maintenance”, up to 1-1.5 years, lifepo4 batteries are used under the same conditions and the theoretical life up to at 7-8. years.
Taken together, the performance-to-value ratio is theoretically more than four times that of lead-acid. The high output current can be charged quickly and output with a maximum current of 2C. In the special charger, the battery can be fully charged in 1.5 minutes after charging 1.5C, and the starting current can reach 2C, but the lead-acid battery has no performance. 4. Good heat dissipation
The peak temperature of lithium iron phosphate can reach 350°C-500°C, while lithium manganate and lithium cobaltate are only about 200°C. Operating temperature range (-20C- +75C), tolerant of low temperature, lithium iron phosphate electric heating the peak can reach 350°C-500°C, while lithium manganate and lithium cobalt oxide are only 200 °C.
5. Lifepo4 battery capacity
It has a larger capacity than ordinary batteries (lead-acid, etc.). Monomer capacity is 5AH-1000AH.
6. Forget it
Rechargeable batteries often work in situations where they are not fully discharged and their capacity quickly drops below full capacity. This phenomenon is called the memory effect. Memory is like nickel-metal hydride and nickel-cadmium batteries, but lifepo4 batteries don’t. Regardless of the state of the battery, it can be used with a single charge and does not need to be discharged and recharged. lifepo4 battery – car jump starter
7. Lightweight lifepo4 battery
The same capacity lifepo4 battery is 2/3 the volume of lead-acid and 1/3 of the weight of lead-acid.
8. Lifepo4 battery is environmental friendly.
Most batteries are considered non-ferrous and non-ferrous metal (Ni-MH batteries must contain non-ferrous metal), non-toxic (SGS certified), no pollution as required. European RoHS regulations, and is a green battery certification. .
So, the reason for the popularity of lithium batteries in industry is usually due to environmental considerations. Therefore, the battery has been placed in the “863” national high-tech development plan in the “fifteenth year plan”, and has become a national critical support and employment support.
China’s accession to the WTO will lead to a further increase in Chinese e-bike exports, and e-bikes entering Europe and the United States will be required to be equipped with non-toxic batteries. .
The performance of a lithium-ion battery generally depends on the material of the anode and the cathode. Lithium iron phosphate is a recent material for lithium batteries. Its safety performance and life cycle are different from other materials. The most important battery information.
Lifepo4 batteries have the advantages of non-toxic, non-polluting, good safety, wide range of raw materials, low cost and long service life. It is an ideal accessory for new generation lithium-ion batteries.
