What are the advantages of lithium iron phosphate batteries

Compared with lithium iron phosphate batteries, we all know that lithium iron phosphate batteries are now widely used in the market. Lithium iron phosphate batteries have five major advantages. Today, I will explain to you:

1, the improvement of safety performance

The P-O bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperatures or overcharges, it will not collapse and heat like lithium cobalt, or form a strong oxidizing substance, so it has good safety.

2. Improved life expectancy

Lithium iron phosphate batteries refer to lithium ion batteries that use lithium iron phosphate as a positive material.

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

3, high temperature performance

Lithium iron phosphate has an electric peak of 350 °C -500 °C while lithium manganese and lithium cobalt phosphate are only around 200 °C. The operating temperature range is wide(-20C -- 75C), lithium ferric phosphate with high temperature resistance can reach an electric peak of 350 °C -500 °C, while lithium manganese and lithium cobalt acid are only around 200 °C.

4, large capacity

The rechargeable battery works under conditions that are often full and un-discharged. The capacity will quickly fall below the rated capacity. This phenomenon is called the memory effect. For example, nickel-metal hydride and nickel-cadmium batteries have memory properties, and lithium iron phosphate batteries do not have this phenomenon. Regardless of the state of the battery, they can be used with charge and do not need to be discharged before charging.

5, light weight

The volume of lithium iron phosphate batteries of the same size is 2/3 of the volume of lead-acid batteries and 1/3 of the weight of lead-acid batteries.
