Battery failure mode1) Positive plate corrosion
Since the battery is lost, the specific gravity of the electrolyte is increased, and the excessive electrolyte acid is exacerbated to the positive plate corrosion.
2) thermal out of control
Thermal out of control refers to a cumulative enhancement effect of the battery when the battery is charged, the charging current and the battery temperature are gradually damaged the battery. From the status survey of current battery, thermal out of control is one of the main reasons for battery failure. The direct consequence of thermal out-of control is the shell drum, leakage, battery capacity, and severely causing a plate-shaped change, and finally invalid. The floating voltage is a long-term charging voltage used for a long term, which is a factor affecting battery life. In general, the floating charge is set to 2.23 to 2.25V / monomer (25 ¡ã C) is relatively suitable.
3) Battery is lost
The valve-controlled lead-acid battery is not essential, ie: the battery should be alive without gas during storage; the charging voltage should not be alive with gas in 2.35V / monomer (25 ¡ã C); there should be no Gas escape. However, when the charging voltage exceeds 2.35V / monomer, it is possible to make the gas escape. At this time, a large amount of gas is generated in a short time in the battery body, and when the negative electrode is absorbed, when the pressure exceeds a certain value, it will start to pass the one-way exhaust valve. Gas, although the gas is filtered out of the acid mist, after all, the battery is lost, so the valve-controlled lead-acid battery charge cannot be charged.
4) Negative electrode plate sulfate
When the valve controlled lead-acid battery is insufficient, PBSO4 is called sulfated sulfate of the active substance, and sulfate reduces the active material of the battery and reduces the effective battery. Capacity, also affects the gas absorption capacity of the battery, and it will fail the battery for a long tim 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
