What’s in a battery?

Ever wonder how that little battery powers your car, laptop or favorite device? We give you an inside look at how most batteries work.
You can think of a battery as a small power plant that converts a chemical reaction into electrical energy. Various dry cell (or alkaline) batteries can differ in several ways, but they all have the same basic components.
Alkaline Batteries

There are 7 parts that make up most alkaline batteries

1.Container: A steel or plastic housing the cell’s components to form the cathode, a part of the electrochemical reaction.

2.Cathode: Cathodes are the electrodes reduced by the electrochemical reaction.

3.Separator: A non-woven, fibrous fabric that separates the electrodes.

4.Anode: Powered zinc metal. Anodes are the electrodes that are oxidized.

5.Electrodes: Where the electrochemical reaction takes place.

6.Electrolyte: A potassium hydroxide solution in water. The electrolyte is the medium for the movement of ions within the cell and carries the iconic current inside the battery.

7.Collector: A brass pin in the middle of the cell that conducts electricity to the outside circuit.
