The full name of lithium iron phosphate ion battery is lithium iron phosphate lithium battery, or simply lithium iron phosphate ion battery. It is the most environmentally friendly, the highest life expectancy, the highest safety, and the largest discharge rate of all current lithium ion battery packs.
The positive electrode of the lithium battery is a compound containing lithium metal, generally lithium iron phosphate (such as lithium iron phosphate LiFePO4, lithium cobalt phosphate LiCoO2, etc.), the negative electrode is graphite or charcoal (graphite is generally used), and between the positive and negative electrodes, organic solvents are used as the electrolyte. When charging the battery, lithium ions are analyzed on the positive electrode to generate lithium ions, which enter the negative electrode of the battery through the electrolyte and are embedded in the micropores of the carbon layer of the negative electrode.

The working principle of lithium iron phosphate ion battery
Lithium iron phosphate lithium ion batteries, refers to lithium batteries that use lithium iron phosphate as the cathode material. The main cathode materials for lithium batteries are lithium cobaltate, lithium manganate, lithium nickelate, ternary materials, lithium iron phosphate, and so on.
When charging the lithium iron phosphate battery, the lithium ion Li+ in the positive electrode migrates to the negative electrode through the polymer diaphragm; in the process of discharging, the lithium ion Li+ in the negative electrode migrates to the positive electrode through the diaphragm. Lithium batteries are named for the back and forth migration of lithium ions during charging and discharging.
When charging lithium iron phosphate ion batteries, Li+ migrates from the 010 surface of the lithium iron phosphate crystal to the surface of the crystal, and under the action of the electric field force, it enters the electrolyte, passes through the diaphragm, and then migrates to the surface of graphene through electrolysis, and then is embedded in the graphene lattice, and at the same time, the electrons flow through the conductor to the aluminum foil electrode of the positive electrode, and then through the electrode lugs, the battery pole, the external circuit, the negative pole, and the negative electrode lugs, and then to the negative electrode's copper foil collector. Fluid, and then through the conductive body to the graphite negative electrode, is the charge of the negative electrode reaches equilibrium, lithium ions from lithium iron phosphate de-embedded, lithium iron phosphate into iron phosphate.
Lithium iron phosphate battery discharge, Li + from the graphite crystal de-embedded out, into the electrolyte, through the diaphragm, and then migrate to the surface of the lithium iron phosphate crystals through the electrolyte, and then re-embedded into the lithium iron phosphate lattice by 010 surface. At the same time, the battery flows through the conductive body to the negative electrode of the copper foil collector, through the lugs, the negative electrode post of the battery, the external circuit, the positive electrode post, the positive electrode lugs, the positive electrode collector, and then through the conductive body to the positive electrode of the lithium iron phosphate, so that the charge of the positive electrode reaches a state of equilibrium.
The above is the analysis of the working principle and chemical reaction equation of lithium iron phosphate ion battery, do you understand? Long-term manufacturing of lithium iron phosphate ion battery packs, can be customized according to customer demand for a variety of use requirements of the battery pack. The company has won the trust of many consumers with thoughtful service, low price and higher quality.
