The first ever battery.
In the 1800's, the first true battery was invented. Many people had tried to create a battery but Alessandro Volta was the first person to ever create one. Since then, many newer and much improved battery's have come around. -
The Daniell Cell
As always with new inventions, there will be flaws. One flaw with the original battery was that hydrogen bubbles would form on the copper. John Frederic Daniell noticed this and set out to fix it. In 1836, Daniell created the Daniell cell. This was the first practical battery and was a huge improvement from the original battery. -
The Lead-Acid battery
Up until this point, a battery could only last so long. Once a battery had been drained of its chemicals, it was useless. But now there was a way to recharge your battery's. In 1859, Gaston Planté created the lead-acid battery. This battery while heavy for its size was able to recharge itself using reverse current. -
The Gravity Cell
As time went by, new technology was created. More and more people started experimenting with the Daniell cell and trying to modify it into something even greater. In 1860, a Frenchman named Callaud invented a variant of the Daniell cell and called it the gravity cell. This battery held a much stronger current and was the main battery used by the American and British telegraph networks. -
The first dry cell
In 1886, Carl Gassner created the dry cell. The reason it is called dry is because it did not have a free liquid electrolyte. Instead, the ammonium chloride was mixed with plaster of Paris to create a paste that was then added to the battery. -
The first alkaline battery
In 1899, a Swedish scientist named Waldemar Jungner invented the nickel–cadmium battery. This battery is rechargeable and had a stronger energy density but was much more expensive. -
Lithium and lithium-ion batteries
In 1997, the lithium polymer battery was released by Sony and Asahi Kasei. These batteries hold their electrolyte in a solid polymer composite instead of in a liquid solvent, and the electrodes and separators are laminated to each other.
