Description
technical field [0001] The invention relates to the technical field related to lead-acid batteries, in particular to a battery desulfurization device and method. Background technique [0002] White hard lead sulfate crystals are formed on the pole plate, and it is very difficult to convert lead sulfate into active substances during charging. This is sulfation, referred to as "sulfurization". The reason for the formation of this lead sulfate is that when the lead sulfate is placed for a long time after over-discharge or discharge, the lead sulfate particles are dissolved in the electrolyte and are in a saturated state. In this way, the once-precipitated particles grow and develop again and again due to temperature changes, making the crystal grains larger. This kind of sulfuric acid has poor conductivity, high resistance, low solubility and dissolution rate, and it is difficult to recover when charging. Therefore, it becomes a cause of a reduction in capacity and a shortene...
