Question

Which of the following statement(s) is/are true about secondary batteries?

• A. It can be recharged
• B. It cannot be reused
• C. Act as galvanic cell during discharge
• D. Act as electrolytic cell during charging

Answer 1

Answer: (A), (C), (D)

Act as electrolytic cell during charging

In secondary batteries, the redox reaction that converts chemical energy into electrical energy can be reversed by passage of current.
After its use, they can be recharged by passing current through it in the opposite direction and can be used again.

These batteries behave as galvanic cells during discharge. Thus, converting chemical energy into electrical energy.
During charging, it will behave as electrolytic cells. Thus, converting electrical energy into chemical energy.

Examples of secondary batteries are Lead storage cell and Nickel-cadmium cell.

Thus, statement (a), (c) and (d) are correct.
