What is lithium iron phosphate battery(LiFePo4)?

1. Longer Cycle Life

Cycle Life of lead-acid batteries about 300 times, with a maximum of 500 times. However, lithium iron phosphate power batteries have a cycle life of reach 6000 times and can be used for 2000 times under standard charging (5-hour rate). The lead-acid battery of the same quality is "new half a year, old half a year, and maintenance and maintenance half a year", which can last from 1 to 1.5 years at most, while the lithium iron phosphate battery will last for 7-10 years under the same conditions. Overall, the cost performance ratio will be more than 4 times that of lead-acid batteries.

2. Safety

Lithium iron phosphate completely solves the safety hazards of lithium cobalt oxide and lithium manganese oxide. Lithium cobalt oxide and lithium manganese oxide can explode in strong collisions, posing a threat to the safety of consumers. Lithium iron phosphate has undergone strict safety testing and will not explode even in the worst traffic accidents.

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

4. High temperature resistance, lithium iron phosphate electrothermal peak value can reach 350 ℃ - 500 ℃, while lithium manganate and lithium cobalt oxide are only around 200 ℃.

5. Green and environmentally friendly: Because it is made of non-toxic, odorless, and environmentally friendly materials, there is no problem of any harmful chemical residue.

6. Large capacity.

2000mah to 340ah lifepo4 capacity all available.

7. No memory effect.

Disadvantages of lithium iron phosphate batteries

Although batteries made of this material have many advantages, they also have certain shortcomings in the process of use. For example, problems such as lower energy density, poor performance at lower temperature, so there will be certain limitations in the actual application range!! In addition, the issue of high costs cannot be ignored.

Application field of lithium iron phosphate battery

Due to the obvious advantages of lithium iron phosphate batteries, they have been widely used throughout the country and even the world. The main application fields include large electric vehicles such as electric buses, light electric vehicles such as electric bicycles, electric tools such as electric saws, solar and wind power storage equipment, and small medical equipment.

Lithium iron phosphate battery manufacturer

Currently, the enterprises producing lithium iron phosphate in China mainly include CATL, BYD, Guoxuan Hi-Tech, EVE Lithium Energy, and other enterprises. CATL has the largest production capacity, with the production of NCM522 ternary materials and LFP 622 quaternary materials ranking first in the world; And Guoxuan Hi-Tech's LPO411 and NPA602 quaternary materials are also in the international leading position.
