LiFePO4 배터리 란 무엇입니까? LiFePO4 배터리의 장점과 특징은 무엇입니까?

What is LiFePO4 battery ?

LiFePO4 is a positive electrode material for lithium ion batteries. LiFePO4 exists in the form of lithium iron phosphate in nature, and its structure is stable, resources are abundant, safety performance is good, and it is non-toxic. Compared with the traditional lithium ion battery cathode materials LiMn2O4 and LiCoO2, LiFePO4 raw materials are more widely available, cheaper and have no environmental pollution.

Advantages of LiFePO4 battery:

1, the long life, long life lead-acid battery cycle life is about 300 times, the highest is 500 times, and Benzo Energy / Ufine Technology Co., Ltd. produced lithium iron phosphate battery, cycle life of more than 1000 times, standard charging (5 hour) can be used up to 2000 times. Lithium iron phosphate batteries are used under the same conditions and will have a service life of 7-8 years. Comprehensive consideration, the performance price ratio will be more than 4 times that of lead-acid batteries.

2, the use of safety, lithium iron phosphate completely solves the safety hazard of lithium cobaltate and lithium manganate. Lithium cobaltate and lithium manganate will explode under strong collisions, posing a threat to consumers' life safety, and iron phosphate Lithium undergoes rigorous safety testing and will not explode even in the worst traffic accidents.

3, the high current 2C can be quickly charged and discharged. Under the special charger, the battery can be fully charged within 40 minutes of 1.5C charging, and the starting current can reach 2C, but the lead acid battery has no such performance.

4, high temperature resistance, lithium iron phosphate electric heating peak up to 350 ° C and lithium manganate and lithium cobalt oxide only at about 200 ° C.

5, large capacity.

6, no memory effect.

7, small size and light weight.

8, green and environmental protection.

LiFePO4 battery characteristics

High-efficiency output: standard discharge is 2~5C, continuous high-current discharge can reach 10C, and instantaneous 10C pulse discharge (10sec) can reach 20C. Excellent service life, its discharge capacity is still greater than 95% after 500 cycles. The safety is high, and the battery does not burn or explode even if it is damaged inside or outside the battery. It has good heat resistance and can withstand charging and discharging speeds of 3~5C or higher.

Good performance at high temperature: When the external temperature of the working environment is 65 °C, the internal temperature will be as high as 95 °C, and the temperature at the end of the battery discharge can reach 160 °C, but the structure of the battery is safe and intact. There is no damage from overdischarge to zero volts. Can be charged quickly. Lithium-iron battery raw materials do not use rare metals, which can greatly reduce costs and have no pollution to the environment.

The operating voltage of the LiFepO4 battery is 3.2V, the termination charging voltage is 3.6V, and the termination discharge voltage is 2.0V. Due to the quality and process of the positive and negative materials and electrolyte materials used by various manufacturers, there will be some differences in their performance. For example, the same model (standard battery of the same package) has a large difference in battery capacity (10% to 20%).

Lithium iron power battery application:

1. Large-scale electric vehicles: buses, electric vehicles and hybrid electric vehicles.

2. Light electric vehicles: electric bicycles, golf carts, small electric scooters, stackers, cleaning vehicles, electric wheelchairs, etc.

3. Power tools: electric drills, chainsaws, lawn mowers, etc.

4. Remote control cars, boats, airplanes and other toys.

5. Energy storage equipment for solar and wind power generation.

6. UPS and emergency lighting warning lights and miner's lamps (safest) and emergency lights

7. Replace the 3V disposable lithium battery in the camera and the 9V nickel-cadmium or nickel-hydrogen rechargeable battery (the same size).

8. Small medical equipment and portable instruments.
