Batteries

Claimed by Nathan Batey

A device used in electric circuits to store and distribute voltage.

The Main Idea

A battery is a device that is commonly used in circuits to distribute a voltage through the circuit's path. The battery uses a chemical reaction to produce a potential difference between the positive and negative terminals. The voltage is produced by the work done on charges inside the battery. Batteries(singular or multiple connected) can technically be referred to as electrochemical cells, and more specifically voltaic cells(because of their nature to produce an external potential difference). When talking about circuits, the potential difference(or voltage) produced by batteries is often referred to as EMF(electromotive force).

Types of Batteries

There are different types of batteries, the main difference being the chemical inside producing the reaction.

-Alkaline Batteries - Containing potassium hydroxide, an alkaline electrolyte, these batteries are one of the most common -Lithium Ion Batteries - A type of rechargeable battery, with one of the best energy-to-weight ratios -Lead Acid Batteries - One of the oldest batteries, these have a very low energy-to-weight ratios, they can provide short high surges of current and are most commonly found in automobiles -Nickel-Cadmium Batteries - another type of rechargeable battery, containing nickel oxide hydroxide and cadmium
