A battery is a small pocket of stored chemical energy which when put to use provides valuable power for millions of gadgets and toys. There are various types of batteries all based on the type of chemicals used to make them for example galvanic cells, electrolytic cells, fuel cells, flow cells and voltaic piles.
There are two main division of battery; they are the primary and the secondary. The primary is intended for one time use, due to the irreversible nature of the reaction taking place inside for example in pen flashlights. The secondary on the other hand is rechargeable and can be reused many times before being fully worn out for example in mobile phones, laptops and cars.
A little history
The earliest artifacts that may have been used as batteries are the Baghdad Batteries, which existed some time between 250 BC and 640 AD, and may have been used for electroplating gold.
Surprisingly a man by the name of Ludwig Galvani attached two different metals to a dead frog’s leg and found out that it twitched. Brrrrr!
Alessandro Volta realized that the frog legs could be replaced by salt. Better!
Many changes have followed on since then and today, we have our modern battery technology.
Battery types
Batteries are used to power millions of electronic products across the world they are available in many sizes, shapes, efficiencies and battery life. The most common are those used to power watches, television and entertainment systems remote controllers, radios, cell phones, laptops and cars.
New technology
To negate the surging energy crisis, such tasks such as charging your mobile phones batteries and such alike on your main power grid. Companies have now been selling and distributing solar powered battery chargers to make charging more convenient and less costly.
These cells have really been an improvement and many consumers are now gravitating towards them as they recognize the need to conserve on energy consumption.
I wonder what is next.
Environmental safety Tip: It is better to send batteries for recycling. The substances in batteries are normally very dangerous to the environment if not properly disposed.
