Changshu Wanlong introduces Lead Acid Storage Battery is a series
of lead plates coated with lead dioxide. The battery contains a
mixture of the battery electrolyte solution, sulfuric acid, and
water.
When the battery is discharged, the acid reacts with lead dioxide
to produce electricity. When charging the battery, electricity is
used to reverse the chemical reaction, thereby moving the sulfate
ions back into the acidic solution.
