What Are The Advantages Of Lithium Iron Phosphate Batteries Compared To Traditional Lead-acid Batteries?

Date:Feb 10, 2019

The advantages of lithium iron phosphate battery compared with traditional lead-acid batteries are mainly reflected in the following aspects. 1) High energy density, the volume and weight of lithium iron phosphate battery is only about one third of the same capacity lead-acid battery. 2) The single lithium iron phosphate battery can achieve 3000 cycles of life under ideal conditions, which is much better than lead-acid batteries (500 cycles). 3) Good temperature performance, especially high temperature performance. Lithium iron phosphate battery has a working range of -20 ° C ~ 60 ° C, and can work under high temperature for a long time without affecting battery life. 4) Power performance is good. Under the premise of not affecting the battery capacity, the lithium iron phosphate battery can meet the needs of large current charge and discharge, and solves the problem of excessive battery capacity loss during the large current discharge of the traditional lead acid battery. At the same capacity, the lithium iron phosphate battery has twice the current output energy of a lead-acid battery. If a lithium iron phosphate battery is used instead of a lead-acid battery for a power-supplied UPS, its capacity will be reduced by 50%. 5) High security. In the harsh conditions such as acupuncture, extrusion, short circuit, overshoot, etc., it is still safe, no deformation, and the capacity retention rate is extremely high. 6) Clean and environmentally friendly, lithium iron phosphate material does not contain any heavy metals and rare metals, no pollution will be caused to the environment during production and use, and the environmental pollution of traditional batteries will be avoided. As the cathode material of lithium battery, lithium iron phosphate is the most safe cathode material for lithium ion battery. Although the tap density is low and the voltage platform is low, the cathode material is safe and stable, causing it to be abused in extrusion, overcharge and short circuit. It is still safe, due to its safety and stability, lithium iron phosphate battery has become an important development direction of lithium-ion battery.
