When the forklift battery is charged, it should be in an external current power supply (charge pole or rectifier), the material generated by the positive and negative plates is restored to the original active substance, and convert the external electrical energy into chemical energy.
On the positive electrode plate, under the action of the external current, the leads of sulfate is dissociated into divalent lead ions (PB2) and sulfate (SO4-2). Since the external power is constantly absorbing electrons from the positive electrode, the positive electrode plate is free. The price of lead ions (PB2) continuously released two electrons to supplement, becomes tetravalent lead ions (PB4), and continued to react with water, ultimately a lead (PbO2) of the positive electrode plate (PBO2).
On the negative plate, under the action of the external current, the leads of sulfate are eluted into divalent lead ions (PB2) and sulfate negative ions (SO4-2), and since the negative electrode is constantly obtaining electronics from the external power supply, the negative electrode plate is free. Price lead ions (PB2) were neutralized to lead (Pb), and attached to the negative plate with velvet lead.
In the electrolyte, the positive electrode is constantly producing free hydrogen ions (H) and sulfate ions (SO4-2), and the negative electrode is constantly producing sulfate ions (SO4-2), and the hydrogen ion moves to the negative electrode under the action of the electric field, sulfate The ion moves to the positive electrode to form a current.
The electrolysis reaction of water will also occur in the solution under the operation of the current.
