What are the advantages and disadvantages of lithium iron phosphate battery

Posted on 2022-08-12

Lithium iron phosphate battery refers to lithium ion battery which uses lithium iron phosphate as cathode material. The cathode materials of lithium ion batteries mainly include lithium cobalt acid, lithium manganese acid, lithium nickel acid, ternary materials, lithium iron phosphate and so on. Lithium cobalt acid is the cathode material used in most lithium ion batteries.

Disadvantages of lithium iron phosphate batteries

1, lithium iron phosphate battery positive electrode vibration density is small

2, the conductivity is poor, lithium ion diffusion speed is slow, high charge and discharge, the actual specific capacity is low.

3. Low temperature performance of lithium iron phosphate battery is poor.

4. The life of a single battery of lithium iron phosphate battery is long, about 2500 times, but the life of lithium iron phosphate battery pack is short, generally about 500 times

The advantages of lithium iron phosphate battery

1, lithium iron phosphate battery life is long, cycle life is more than 25, 00 times. Lithium iron phosphate batteries can last seven to eight years under the same conditions.

2, use safety. Lithium iron phosphate batteries undergo rigorous safety tests and do not explode even in traffic accidents.

3, fast charging. Using a special charger, the battery can be fully charged at 1.5C for 40 minutes.

4, lithium iron phosphate battery high temperature resistance, lithium iron phosphate battery hot air value can reach 350 to 500 degrees Celsius.

5. The capacity of lithium iron phosphate battery is large.

6. Lithium iron phosphate battery has no memory effect.

7, lithium iron phosphate battery green environmental protection, non-toxic, pollution-free, wide source of raw materials, cheap price.

The application field of lithium iron phosphate battery

Large electric vehicles: buses, electric vehicles, sightseeing buses and hybrid vehicles, etc.

Light electric vehicle: AGV industrial robot, warehouse PSB picking cart, electric bicycle, golf cart, small flat battery car, forklift car, cleaning car, electric wheelchair, etc.

Power tools: electric drill, saw, lawn mower, etc.

Remote-controlled cars, boats, airplanes and other toys;

Energy storage for solar and wind power;

UPS and emergency lights, warning lights and mine lights (safety is the best);

Replace the 3V disposable lithium battery and the 9V nickel-cadmium or nickel-metal hydride rechargeable battery in the camera (identical size);

Small medical equipment and portable instruments, etc.
