A secondary cell or battery is one that can be electrically recharged after use to their original pre-discharge condition, by passing current through the circuit in the opposite direction to the current during discharge.
What is secondary cell example?

| Primary cell | Secondary cell |
|---|---|
| Zinc-carbon cell | Nickel-cadmium cell |
| Alkaline cell | Lithium-ion cell |
| Lithium cell | Nickel metal hydride cell |
| Mercury cell | Lead-acid battery |
What is secondary cell answer?
Secondary cells are those cells that can be recharged and are called accumulators or storage cells. Explanation. In secondary cells, the reactions can be reversed by an external source of electric energy. Secondary cells can be recharged by passing electric current and can be used again.
What is secondary cell Class 12?
An electric cell that can be rechargeable and can therefore be used to store electrical energy in the form of chemical energy is called secondary cell.
Is Daniel cell a secondary cell?
Daniel cell is a primary cell while lead storage cell is a secondary cell.
What is secondary cell in biology?
The secondary cell wall is a structure found in many plant cells, located between the primary cell wall and the plasma membrane.Secondary cell walls provide additional protection to cells and rigidity and strength to the larger plant.
Which is primary cell?
Definition of primary cell
: a cell that converts chemical energy into electrical energy by irreversible chemical reactions.
What is secondary cell Ncert?
The secondary cells are repeated action cells.In these cells, the electrical energy is stored in the form of chemical energy. Therefore, these cells are also called storage cells or, accumulators. Lead-acid cell, (or lead storage cell), nickel-cadmium cell etc., are typical secondary cells.
What is primary cell and secondary cell?
Primary Cell and Secondary Cell. Battery or cells are referred to as the parallel combination of electrochemical cells. The major difference between a primary cell and the secondary cell is that primary cells are the ones that cannot be charged but secondary cells are the ones that are rechargeable.
Is dry cell A secondary cell?
There are two basic types of batteries: primary and secondary. Primary batteries are “single use” and cannot be recharged. Dry cells and (most) alkaline batteries are examples of primary batteries. The second type is rechargeable and is called a secondary battery.
What is Lakeland cell?
The Leclanché cell is a battery invented and patented by the French scientist Georges Leclanché in 1866.The chemistry of this cell was later successfully adapted to manufacture a dry cell.
Is Daniell cell dry cell?
At cathode because there is removal of metal ions from electrolyte, electrons from cathode are used up and therefore cathode is fairly positive.
Why is cathode positive in the Daniell cell?

Which cells have a secondary cell wall?
Secondary walls are mainly found in tracheary elements (tracheids in seedless vascular plants and gymnosperms and vessels in angiosperms) and fibers in the primary xylem and the secondary xylem (wood) (Fig. 1).
What is primary secondary and tertiary cell wall?
A plant cell wall may have 2 – 3 parts : primary wall, secondary wall and occasionally tertiary wall. Primary wall is thin elastic and contains cellulose, hemicellulose, pectic substances, lipids and proteins. The chief components of secondary wall are cellulose, hemicellulose and lignin.
What is S1 S2 S3 in cell wall?
S1, S2, and S3 are layers of the secondary cell wall. MIDDLE LAMELLA. The outermost layer of the cell wall and the first to form is the middle lamella. It acts as a glue that binds neighboring cells. It is the only layer synthetized and shared by two contiguous cells.
Is Daniel cell a primary cell?
Daniel cell is a primary cell while lead storage cell is a secondary cell.
Is galvanic cell a primary cell?
A primary cell is a battery (a galvanic cell) that is designed to be used once and discarded, and not recharged with electricity and reused like a secondary cell (rechargeable battery). In general, the electrochemical reaction occurring in the cell is not reversible, rendering the cell unrechargeable.
Where are secondary cells used?
Cells that are essentially utilized as primary cells, but are recharged after use rather than being discarded. Examples of these types of secondary cells primarily include portable consumer electronics and electric vehicles.
What is secondary cell in electrochemistry?
Rechargeable batteries (also known as secondary cells) are batteries that potentially consist of reversible cell reactions that allow them to recharge, or regain their cell potential, through the work done by passing currents of electricity.
What are primary cells Class 12?
A primary cell is a cell that is designed to be used once and discarded, and not recharged with electricity and reused like a secondary cell. In general, the electrochemical reaction occurring in the cell is not reversible, and so these cells cannot be recharged. Physics.
What is galvanic cell Class 12?
Hint:A galvanic cell is an electrochemical cell in which there occur some simultaneous chemical changes in order to produce electricity. These chemical changes include several redox reactions which provide a transfer of electrons throughout the cell.
