Solution
Secondary cells
Secondary cells generate current as a result of reversible chemical processes.
When current is sent through it, it changes electrical energy into chemical energy.
When current is pulled from it, it converts chemical energy back into electrical energy.
Examples: Phone batteries, lead storage batteries, and some AA/AAA batteries too which are rechargeable.
Lead storage battery
When a lead-acid battery discharges, Lead sulfate is applied to both plates of the battery, covering both.
Water is produced during the reaction at the Lead oxide plate, which causes the specific gravity of the sulfuric acid solution to fall.
As a result, the rate of reaction slows, suggesting that the potential difference between the plates also narrows throughout the discharging process.
A lead-acid battery's sulfuric acid concentration contributes to the production of the electrolyte solution, which enables current passage between the two plates.
During the working of the lead storage battery, the concentration of decreases.
