Why batteries are essstial

Batteries are devices that produce electricity and contains one or more electric cells that can store chemical energy and turn it into electrical energy. This piece of electronic technology is essential in my life because batteries are able to power almost everything from phones and vehicles to radios and lights. Also some batteries are portable which you take just anywhere with in your portable electronic device. Some batteries can last an extremely long thing which helps when they are powering a device that needs lots of electricity. The way batteries work is that when you put them into an electrical device the stored chemical energy converts into electrical energy which travels out of the battery and into the device causing it to power on, Batteries have three parts, an anode(-), a cathode(+), and the electrolyte.The chemical reactions in the battery causes a build up of electrons at the anode. This results in an electrical difference between the anode and the cathode. The difference is unstable electrons that will go to the cathode when the circuit of the device is closed causing it to have power. Batteries offer us limitless benefits which makes them essential in my life .
