Answer 1

$\huge\underline\bold\red{AnSwer :-}$

1 .Electric Cell:-

• Electric cell is a device which produces electric current because of chemical reaction.
• The flat base is the negative (-) end of the cell. ... A cell usually produces 1.5 V of current.

2.a. difference between primary and secondary cells :-

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. Examples of secondary batteries include nickel-cadmium (NiCd), lead acid, and lithium ion batteries.

b.Explanation:

$⟹$Button Cell :-

• The button cell, also known as coin cell, enabled compact design in portable devices of the 1980s. Higher voltages were achieved by stacking the cells into a tube. Cordless telephones, medical devices and security wands at airports used these batteries.

• Although small and inexpensive to build, the stacked button cell fell out of favor and gave way to more conventional battery formats. A drawback of the button cell is swelling if charged too rapidly. Button cells have no safety vent and can only be charged at a 10- to 16-hour charge; however, newer designs claim rapid charge capability.

• Most button cells in use today are non-rechargeable and are found in medical implants, watches, hearing aids, car keys and memory backup.
