14.6V Lifepo4 Charger

Description

Solar charge controller for lifepo4 batteries and Lithium iron phosphate battery is a lithium-ion battery using lithium iron phosphate (LiFePO4) as the positive material and carbon as the negative material. The rated voltage of the monomer is 3.2V and the charging cut-off voltage is 3.6V ~ 3.65v.

During charging, some lithium ions in lithium iron phosphate are removed and transferred to the negative electrode through electrolyte, and embedded into the carbon material of the negative electrode; At the same time, electrons are released from the positive pole and reach the negative pole from the external circuit to maintain the balance of chemical reaction. In the process of discharge, the lithium ion comes out of the main pole and reaches the positive pole through the electrolyte. At the same time, the negative pole releases electrons and reaches the positive pole from the external circuit to provide energy for the outside world.

Principle and characteristics of charge and discharge of lithium iron phosphate battery. Lithium iron phosphate ion battery refers to a lithium ion battery using lithium iron phosphate as the cathode material. Lithium iron phosphate ion battery has the advantages of high-efficiency output, fast charging and no pollution to the environment. The chemical performance of lithium iron phosphate crystal is stable. In practical use, it will not burn or explode even under the conditions of outdated charging or high temperature.

Charge and discharge principle of lithium iron phosphate battery

When the lithium iron phosphate battery is charged, the lithium ion Li + in the positive electrode migrates to the negative electrode through the polymer diaphragm; During the discharge process, the lithium ion Li + in the negative electrode migrates to the positive electrode through the diaphragm. Lithium ion battery is named because lithium ions move back and forth during charge and discharge.

1. When the 14.6V lifepo4 charger battery is charged

Li + migrates from the 010 surface of lithium iron phosphate crystal to the crystal surface. Under the use of electric field force, it enters the electrolyte, passes through the diaphragm, then migrates to the surface of graphite crystal through the electrolyte, and then embedded in the graphite lattice. At the same time, electrons flow to the aluminum foil collector of the positive electrode through the conductor, to the copper foil collector of the negative electrode through the pole lug, battery pole column, external circuit, negative pole column and negative lug, and then to the graphite negative electrode through the conductor, so as to balance the charge of the negative electrode. After lithium ion is de intercalated from lithium iron phosphate, lithium iron phosphate is transformed into iron phosphate.

2. When the battery is discharged

Li + is removed from the graphite crystal, enters the electrolyte, passes through the diaphragm, then migrates to the surface of lithium iron phosphate crystal through the electrolyte, and then embedded into the lattice of lithium iron phosphate through 010 surface. At the same time, the battery flows to the copper foil collector of the negative electrode through the conductor, to the aluminum foil collector of the positive electrode of the battery through the pole lug, battery negative pole, external circuit, positive pole post and positive pole lug, and then to the lithium iron phosphate positive electrode through the conductor, so as to balance the charge of the positive electrode.

According to the working principle of lithium iron phosphate battery, the charging and discharging process of lithium iron phosphate battery needs the joint participation of lithium ion and electron, and the migration speed of lithium ion and electron should be balanced. This requires that the positive and negative electrodes of lithium-ion batteries must be mixed conductors of ions and electrons, and their ionic conductivity and electronic conductivity must be consistent. However, it is well known that the conductivity of lithium iron phosphate is very poor. Although the conductivity of graphite negative electrode is better, in order to realize large rate discharge, it is still necessary to improve the conductivity of the negative electrode to balance its electronic conductivity with the ability of lithium ion to be de embedded from graphite
