Batteries have become an integral part of our daily lives. Every technological thing that is used
today runs on batteries of some sort; phones, laptops, televisions, controllers, cars, the list goes
You can easily find batteries of your choice on websites like Spares2you. Though batteries are so
important and are the power source to some of the most significant things that allow the human
life to prosper, yet very little information is known about them. It is time that you learned about
the history of batteries.
Alessandro Volta was a scientist the end of the 1700’s. After a partner of his found that a frog he
recently dissected twitched when he touched it with his metal rod, he investigated the
phenomena. He hypothesised that the twitch actually came from two different metals interacting
together through a moist intermediary and ran experiments to prove it. Nine years later, in 1800,
after many tests and experiments, he created the first battery with a stack of copper and with a
layer of cloth completely soaked in brine in between. However, he soon found that short-circuits
were occurring because of the towel leaking, resulting in a short battery life.
John Frederic Daniell was a British Scientist who wanted to resolve the issues from Volta’s
battery. In 1936, he invented the Daniell Cell. This battery contained of a copper pot full of a
copper sulphate solution that was then filled with porous earthenware, thus allowing ions to pass
through without the solutions mixing. The cell was a vast enhancement of the previous battery
because of its reliability. It became the standard industry use and was used with the telegraph
networks. This was the greatest wet battery invention before dry cells were created.
Wet cells were inconvenient because they spilt, required maintenance, and only had limited use.
Carl Gassner invented it in 1886 by using a paste instead of a liquid electrolyte. Over time, the
National Carbon Company mass-produced a version of the battery created by Gassner, though
they eventually replaced the paste with coiled cardboard, making it easier to manufacturer. The
Zinc-Carbon cell became the industry standard for over 50 years, most notably leading to the
powering of the flashlight.
Lithium became very important for batteries because of multiple reasons. It has the lowest
density while boasting highest electrochemical potential, along with the energy-to-weight ratio.
It was also very lightweight and small. Throughout a majority of the 1900’s experimentation
occurred, eventually leading to three-volt lithium batteries for cameras and very small devices. In
1997, Sony released the lithium polymer battery. These batteries hold their electrolyte in the
form of a polymer composite that is solid, rather than a liquid solvent. The difference allows it to
be encased in a wrapping that is flexible, instead of a metal casing, allowing it to be shaped to a
particular device. These are the batteries that power almost all brands of smart phones.
Batteries Have Come a Long Way
Batteries evolved from something that could barely emit a volt of energy for one minute to
powerful energy that powers mobile phones for hours and hours a day. It took over a hundred
years of experimentation and knowledge to get to the point they are at today. A few companies
have become battery powerhouses and are constantly researching to create more efficient
batteries. Whether you use Energizer batteries or Duracell rechargeable batteries, remember
the hard work that has gone into advancing the technology.
