Analysis of advantages of lithium iron phosphate battery pack.lithium iron phosphate battery energy storage

　　Energy density: Li-ion batteries are smaller and lighter than lead-acid, nickel-cadmium and nickel-hydrogen batteries.

　　Small size and light weight. The volume of lithium iron phosphate battery is 1/3 of that of lead-acid battery, and its weight is 1/3 of that of lead-acid battery.

　　Long service life: the cycle life of lithium-ion battery is 1200~2000 times, but the traditional lead-acid battery is only 500~900 times.

　　High temperature performance: the thermal peak of lithium iron phosphate battery can reach 350 ℃ - 500 ℃, while that of lead-acid battery is only about 200 ℃.

　　High rate discharge: the discharge curve of lithium iron phosphate battery can reach 90% even at the discharge rate of 5C.

　　Fast charging: It can charge and discharge the battery quickly at high current of 2C. The battery can be fully charged within 40 minutes after charging at 1.5C with a special charger. The starting current can reach 2C, but the lead-acid battery does not have this performance now.

　　Safety and environmental protection: lithium iron phosphate battery pack has passed strict safety test and will not explode. It is a green lithium-ion battery.

　　No memory effect: lithium iron phosphate battery pack does not have this phenomenon. No matter what state the battery is in, it can be used at any time. It does not need to be discharged completely before charging.

　　The selection of cathode materials for lithium ion batteries is mainly based on the following factors:

　　1) It has a high redox reaction potential, which makes the lithium ion battery reach a high output voltage;

　　2) The high content of lithium element and the high stacking density of materials make the lithium ion battery have a high energy density;

　　3) The structural stability in the chemical reaction process is better, which makes the lithium ion battery have a long cycle life;

　　4) The conductivity should be high, so that the lithium ion battery has good charge-discharge rate performance;

　　5) Good chemical stability and thermal stability, not easy to decompose and heat, making lithium-ion batteries have good safety;
