Primary and Secondary Cells
What are primary and secondary cells?
Primary and Secondary Cells
Here is a brief explanation of primary cells and secondary cells.
· Primary Cells
These cells are for one-time use only. Once used completely, it should be discarded. These types of cells cannot be recharged or reused. If keenly observed, the label of these cells provides a caution notice saying it must not be recharged; if recharged, it can explode. Primary cells are commonly found and used in most of the electric toys, clocks, wrist watches, and domestic remote controllers.
· Secondary Cells
These cells are also known as chemical cells. Unlike primary cells, these are rechargeable. Due to a chemical reaction, the cell’s electricity gets reversed, and as a result, the same cells can be saved and reused multiple times after the recharging process. All of the battery packs inside those automobiles are made of secondary cells. Another common use for secondary batteries is for starting, lighting, and ignition in vehicles.
· Key difference between primary cell and secondary cell
a) Primary cells don’t solve long-term objectives. Secondary cells can be considered for long-term use.
b) Primary cells are cost-effective, while secondary cells are comparatively expensive.
c) Primary cells are easy to use. Secondary cells are complex in usage.
d) Secondary cells have higher
self-discharge capability as compared to primary cells.
