What are the problems of lead-acid batteries compared with lithium iron phosphate batteries?

Compared with lithium iron phosphate batteries, lead-acid batteries have some problems. Lead-acid batteries (VRLA), the electrodes are mainly composed of lead and its oxides. The electrolyte is a storage battery with sulfuric acid solution. Lead-acid battery charging. The important component of the positive electrode is lead dioxide, and the important component of the negative electrode is lead. An important component of the anode and cathode is lead sulfate. Lead-acid battery structure 1 classification and performance are based on the structure and use of lead-acid batteries. Batteries can be roughly divided into four categories: (1) Lead-acid batteries for future use; (2) Lead-acid batteries for power use; (3) Fixed valve-regulated sealed lead-acid batteries; (4) Other categories, including small-scale valve-regulated sealed lead-acid batteries , Lead-acid batteries for miner's lamps, etc. The nominal voltage of a single grid lead-acid battery is 2.0V. Discharge 1.5V and charge 2.4V. In the application. The nominal 12V lead-acid battery is usually composed of 6 single-dot lead-acid batteries connected in series. 2 important features of 24V, 36V, 48V, etc. (1) Safety seal: normal operation. The electrolyte will not leak from the battery terminals or the case. (2) No free acid: There is a special absorbent barrier to isolate the acid inside. There is no free acid in the battery, so it can be placed anywhere. (3) Bleeding system: When the pressure in the battery exceeds the normal level, the valve-regulated lead-acid battery will release excess gas and automatically reseal to ensure that there is no excess gas in the battery. (4) Simple maintenance: Due to the unique gas compounding system, no water is required in the process of using VRLA batteries to convert the gas that appears into the prestige water. (5) Long service life: The lead-calcium alloy guardrail anti-corrosion VRLA battery can be floated for 10-15 years. (6) Stable quality and high reliability: VRLA battery has stable quality, reliable performance, advanced processing technology and strict quality control system. Check the voltage capacity and sealing line at 100%. (7) Safety certification: All VRLA batteries have passed UL certification. 3. Preventive measures before use (1) Ensure that there is sufficient insulation between and around the battery and the device. Inadequate insulation may cause electric shock. Short-circuit heating, smoking or burning. (2) When using a charger for charging, directly connecting to a DC power supply may cause battery leakage, heat generation or burning. (3) Self-discharge. The battery capacity will slowly decrease. After long-term storage, please charge the battery before use. Combining the above comparative analysis, it is not difficult to see. The performance of lithium iron phosphate batteries is far superior to that of lead-acid batteries, so it was included in the 863 National High and New Technology Development Plan during the tenth period and became a key development project supported and encouraged by the state. Therefore, as a kind of electric vehicle battery, lithium iron phosphate will be a wise choice in the long-term strategic sense!
