Application difference between AGM type battery, GEL type battery, lithium-ion battery

Application difference between AGM type battery, GEL type battery, lithium-ion batteryThe working principle of the lead battery is that the anode (PbO2) and cathode (Pb) in the lead storage battery are immersed in the electrolyte (dilute sulfuric acid), and the two poles produce 2V power. Chemical changes in discharge are dilute sulfuric acid to react with the active substance on the yin and anode plate, and the new compound "lead" "." It is released from the electrolyte via the discharge sulfuric acid ingredient, and the concentration of the sulfuric acid is slurly.

The ingredients consumed were proportional to the amount of discharge, and as long as the concentration of the sulfuric acid in the electrolyte, the amount of discharge or residual power can be known. The chemical change in charging is discharged when discharge is discharged, and the lead in the cathode plate is decomposed to be decomposed into sulfuric acid, lead, lead and pegrated lead, so that the concentration of the electrolytic solution in the battery is gradually increased, i.e., electrolyte The specific gravity rises, and gradually returns the concentration before the discharge, which shows that the active substance in the battery has been restored to a state in which the power is re-powered, and when the sulfate of the two is reduced to the original active material, that is, equal to charging end However, the cathode plate produces hydrogen, the anode plate produces oxygen, charging to the final stage, the current is almost used in hydroelectric solution, so that the electrolyte will decrease, at which time the electrolyte should be supplemented with pure water.

The AGM type battery is a battery that is filled with dilute sulfuric acid, and the dilute sulfuric acid is absorbed in a super fine glass fiber separator and a plate, and there is almost no flow electrohytic liquor. Most of the electric bicycle batteries sold in the market are AGM type batteries.

The GEL-type colloidal battery is no free electro-liquid after electrolyte gel, and the vulnerability is much smaller than the previous battery; the amount of perfusion is 10 to 15%, and there is less water, so the colloidal battery will not Painlessness caused failure; the incubation of colloid increased the strength of the separator, protecting the polar plate, making up for the defects of acid contraction, so that the assembly pressure is not significantly reduced is one of the reasons for extending battery life; colloid filling The gap between the partition and polar plates reduces the internal resistance of the battery, and the charging acceptance ability can be improved. Therefore, the over-discharge of the colloidal battery is superior to the AGM-type battery than the AGM type battery; the consistency of colloidal batteries is much better than the same AGM battery. There are four of the following colloids that have been bracomized in China: gas phase glue, silica sol, mixed glue, silicone high polymer glue.

When the battery is charged, the lithium in the positive electrode material is detached from the diaphragm to the negative electrode graphite; when the battery is discharged, the lithium ion is pulled out from the negative electrode graphite, and the diaphragm is returned to the positive material. middle. Lithium ions are constantly embedded and discharged from the positive and negative electrodes with the charged discharge.

Lithium-ion battery is a secondary battery. Because it has high energy density, high current charge, no memory effect, low cost, etc. Winners in the secondary battery. Since the 1990s, there has been a lithium battery in a button battery, mobile phone, and DC digital product in electronic products, and is currently used in electric bicycles. However, the cost of lithium ion battery accounted for one-third of the cost of electric vehicle, far greater than the proportion of lead-acid batteries in the whole vehicle. Moreover, since the lithium battery is higher than the energy, the material stability is poor, the lithium battery is prone to security issues. With the development of technological development, lithium-ion batteries will become the development trend of high quality electric vehicles.  Recommend: LiFePO4 Battery Manufacturer Energy storage battery Manufacturer Integrated machine energy storage battery series Manufacturer Lead lithium battery Manufacturer Outdoor Backup Battery Manufacturer Portable outdoor power supply Manufacturer Power battery Manufacturer Powerwall LiFePO4 Battery Manufacturer Battery rack Manufacturers Telecom LiFePO4 Battery Manufacturer Wall mounted battery storage Manufacturer China Lifepo4 Battery
