Question

Which among the following is an example of secondary cells?

• A. Leclanche cell
• B. Lead-storage battery
• C. Dry cell
• D. Alkaline cell

Answer 1

The correct option is B

Lead-storage battery

Secondary cells:

A secondary cell or battery seems to be one that may have been electrically restored or refilled to its original pre-discharge state after usage by flowing flow of electrical current throughout the reverse direction as even the current before discharge.

The explanation for the correct option:

In the case of option B,

1. The lead storage battery is also known as a lead-acid battery.
2. The lead battery has been comprised of two chemically different lead-based plates submerged inside a sulphuric acid solution using lead alloy ingots as well as leading oxide. Reversible chemical processes take place throughout the secondary cells.
3. Reversible chemical processes take place in secondary cells. By sending a current across the battery, the reactants that once again create an electric current within those batteries might well be replenished. Discharging seems to be the chemical process of removing current through a secondary battery. Charging seems to be the process of renewing active material.

The explanation for the incorrect options:

1. In the case of option A, the Leclanche cell is a foremost cell that is useful for sporadic usage, having a positive anode of zinc surrounded by a porosity combination of manganese dioxide and powdery carbon.
2. In the case of option C, dry cells are devices comprised of one or maybe more electrochemical cells that transform stored chemicals into electrical energy.
3. In the case of option D, an alkaline cell is a long-lasting dry cell with an alkaline electrolyte that reduces cell corrosion.

Therefore, option B (lead-storage battery) is the correct answer.
