From a scientific theoretical point of view, the devices that store electrical energy are called batteries, piles or accumulators, which are sophisticated devices made up of electrochemical cells (units capable of converting the chemical energy inside them into electrical energy) that provide electrical energy mainly for the ignition of combustion engines and the ignition of multiple technological devices.

Now, having explained what a battery is and how this device works, it is necessary to mention that batteries have played an important role in our daily life since their invention, essentially because this technological advance has provided us with non-reversible chemical energy to charge our electronic devices throughout this time.
In order for a battery to generate non-reversible chemical energy, oxidation-reduction reactions of certain chemical substances must occur inside the battery, one of which loses electrons while the other gains electrons. Among the chemical reactions that produce the most energy are those generated in alkaline conditions between zinc and manganese dioxide, acid/lead reactions, nickel, nickel/cadmium, nickel/hydride, lithium ions, lithium polymer and others of lesser use such as nickel/iron.

Paradoxically, more than two centuries after the invention of batteries, science has been reorienting the use of conventional batteries towards the use of more environmentally friendly batteries, and they have found that the nickel-iron battery invented by Thomas Edison is more efficient and resistant to tolerate insufficient charge and overcharge better than the batteries mentioned in the previous paragraph.

OBSERVATION
Till today Thomas Edison work is been celebrated and that is because of the great thing he does when he was actually alive. I was really able to learn quite a lot from his life. Till today there are lots of inventions that we credit Thomas to and that is because he works on the invention.
One of the things that we should strive for is that we are able to still be relevant whether we are alive or dead and that will be determined by what we do and what we introduce that id unique and special
