Lead-acid battery and lithium iron phosphate battery as compared to what issues?

Source: 2020 - 04 - 12 and he hits: lead-acid battery and lithium iron phosphate battery than there are some problems in lead-acid storage battery ( VRLA) , the main electrode made of lead and its oxide. The electrolyte is a battery of the sulfuric acid solution. Lead-acid battery charging. The main composition of the anode is lead dioxide, a major component of the cathode is lead. The main components of the anode and the cathode is lead sulfate. Lead-acid battery structure 1 classification and performance according to the structure of the lead-acid battery and USES. Battery is roughly divided into four categories: ( 1) In the future use of lead-acid battery; ( 2) Power use lead-acid batteries; ( 3) Fixed valve control sealed lead-acid battery; ( 4) Other categories, including small valve-control sealed lead acid battery, with lead-acid battery miner's lamp, etc. The nominal voltage of 2 single grid lead-acid battery. 0V。 Discharge 1. 5 v, charging 2. 4V。 In the application. Nominal 12 v lead-acid battery is usually composed of section 6 single lattice lead-acid batteries in series. 24 v, 36 v, 48 v 2 main characteristics (such as 1) Security seal: normal operation. The electrolyte will not from the battery terminal or shell leakage. ( 2) No free acid: there is a kind of special absorbent barrier isolates acid in it. There is no free acid battery, so can be placed anywhere. ( 3) Vent system: after the battery internal pressure than normal, valve control type lead acid battery will release redundant gas, and automatically seals, guarantee no excess gas in the battery. ( 4) Simple maintenance: due to the unique gas composite system, the use of VRLA batteries will produce gas into water process doesn't need. ( 5) Long service life: lead calcium alloy guardrail anti-corrosion VRLA battery, floating 10 - 15 years. ( 6) Stable quality, high reliability, VRLA battery quality is stable, reliable performance, advanced production technology, strict quality control system. By ten o % check and seal line voltage capacity. ( 7) Safety certification: all VRLA batteries are passed UL certification. 3. Preventive measures (before use 1) Make sure the battery with the equipment and the surrounding have enough insulation. The insulation of the inappropriate may cause electric shock. The short circuit heating, smoking or burning. ( 2) Charge charger, connect directly to the dc power supply may cause battery leakage and heat or burning. ( 3) Self-discharge. Battery capacity will gradually reduced. After long time storage, please recharge the battery before use. Combining with above comparative analysis, it is not hard to see. Lithium iron phosphate battery performance is much better than the lead-acid batteries, therefore be included in the '863 national high and new technology development plan during the' 15 ', become a national key support and encourage the development of the project. So the lithium iron phosphate, as a kind of electric vehicle batteries will be the best choice of long-term strategic sense.
