The advantages of lithium iron phosphate battery (lifepo4 battery) compared with lead-acid battery are mainly reflected in the following aspects
1) High energy density, the volume and weight of the lithium iron phosphate battery (lifepo4 battery) is only about one-third of the lead-acid battery of the same capacity.
2) The cycle life of a single lithium iron phosphate battery (lifepo4 battery) under ideal conditions can reach 3000 times, which is much better than that of lead-acid batteries (500 cycles of use).
3) Good temperature performance, especially outstanding high temperature performance. The working range of lithium iron phosphate battery can reach -20 ℃ ~ 75 ℃, and it can work at high temperature for a long time without affecting the battery life. In extremely cold weather, it cannot fully discharge normal power or cannot be used normally.
4) Good power performance. Without affecting the battery capacity, the lithium iron phosphate battery can meet the needs of high current charging and discharging, and solve the problem of excessive battery capacity loss when the traditional lead-acid battery is discharged at a high current. In the case of the same capacity, the high-current output energy of the lithium iron phosphate battery is about twice that of the lead-acid battery. If the lithium iron phosphate battery is used to replace the lead-acid battery in the power backup UPS, its capacity will be reduced by 50%.
5) High security. It is still safe under harsh conditions such as acupuncture, extrusion, short circuit, overcharge, etc., no deformation, no fire, no explosion, and a very high capacity retention rate.
6) Clean and environmentally friendly, the lithium iron phosphate (lifepo4 battery) material does not contain any heavy metals and rare metals, which will not pollute the environment during production and use, avoiding the pollution of traditional batteries to the environment.
Lithium iron phosphate (lifepo4 battery), as the positive electrode material of lithium battery, is the safest positive electrode material for lithium ion battery at present. Although the tap density is low and the voltage platform is low, due to the safety and stability of the positive electrode material, it can be used in extrusion, overcharge, etc. It is still safe under short-circuit and other abuse conditions. Due to its safety and stability, lithium iron phosphate batteries have become an important development direction of lithium-ion power batteries.
