What are the Differences in Batteries?

Home  /  Electronic Components  /  What are the Differences in Batteries?

If you have to purchase a lot of batteries, it is worth knowing what it is that sets one brand and one type apart from others.

All batteries work in pretty much the same way, as they don’t store electricity, they store energy. They do this in the form of chemicals, which upon being introduced to a circuit start a chemical reaction, which is what produces the electricity.

So, as all batteries essentially work in the same way, what sets them apart from each other? Size is one of the main ones, of course, but the other big factor is the chemicals that are being used. Lithium and Sodium, two closely related elements are commonly found in batteries, and in virtually all cases, Lithium produces more efficient batteries.

The batteries that are used in phones and cars are always lithium-ion batteries. The actual chemical used is usually a mixture of lithium cobalt oxide, which breaks apart upon contact with a circuit and merges back together upon contact with a current.
