Two methods of curing the battery
Two methods of curing the battery: the use and cycle life of the battery are inseparable from daily maintenance. For batteries, one of the essential methods for maintenance is to regularly replenish the battery with pure water.
1. Hydrotherapy:
For sulfurized batteries, discharge the battery first, pour out the original electrolyte and inject a dilute electrolyte with a density below 1.10g / cm3. Add water to the battery to dilute the electrolyte to improve the solubility of lead sulfate. Use a current below 20 hours, charge for a long time in the temperature range of 20 ~ 40 ℃, and then adjust the density of the electrolyte in the battery to the standard solution concentration with a slightly higher electrolyte when the battery is fully charged. Can be released, the capacity restored to more than 80% can be considered a successful repair.
The principle of hydrotherapy is to reduce the density of acid solution to increase the solubility product of sulfate, take a small current to charge for a long time to reduce ohmic polarization, delay the early appearance of water decomposition voltage, and make the vulcanization phenomenon gradually dissolve and transform into active substances. Lighten or eliminate. The characteristics of hydrotherapy are more suitable for water storage batteries, and can also be treated repeatedly for the phenomenon of more severe sulfurization, without the need to invest in equipment to repair itself, the disadvantage is that the process is too complicated, and it is not suitable for sealed (maintenance-free) batteries.
2. Charging method:
For sulfurized batteries, use a large current within 5 hours. It is advisable to charge the battery to a slightly overcharged state and control the liquid temperature to not exceed 40 degrees, and then discharge it 30%. Repeatedly to reduce and eliminate the sulfuration phenomenon. The principle of the charging method is to use overcharge to precipitate the gas, scour the surface of the plate slightly with sulfide, dissolve it and convert it into an active material. The charging method can obviously repair the slight vulcanization phenomenon. However, it is not applicable to old batteries, because the precipitated gas scours the sulfate and also strongly scours the active material of the positive electrode plate, which makes the active material soft or even falls off.
