Lithium iron phosphate battery is a lithium battery with lithium iron phosphate (LiFePO4) as the positive electrode material. The nominal voltage of a single-cell lithium battery is 3.2V, the highest charging voltage is 3.9V, and the lowest discharging voltage is 2.0V.
The lithium iron phosphate battery has extremely high thermal stability, will not explode when the temperature is too high, and has excellent safety performance;
In terms of practicability, lithium iron phosphate batteries have superior high-rate discharge performance, strong overcharge resistance, stable charge and discharge status, minimal pollution, no memory effect, and a cycle life of more than 2,000 times.
working principle
Lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as a positive electrode material. The cathode materials of lithium-ion batteries mainly include lithium cobaltate, lithium manganate, lithium nickelate, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material used in the vast majority of lithium-ion batteries.
