Lithium-ion batteries date back to the 1970s

Stanley Whittingham, a British chemist, first put forward the concept of lithium batteries in the 1970s while working for the American oil and gas multinational Exxon. Initially, the batteries he made were not practical. This changed when researchers began using only lithium compounds, which could accept and release lithium ions.

In 2019, John Goodenough, Stanley Whittingham and Akira Yoshino were awarded the Nobel Prize in Chemistry for “the development of lithium ion batteries.”

Batteries have been around a long time

We have been using batteries (non-lithium) for hundreds of years. Alessandro Volta, an Italian physicist, described the world’s first electrochemical battery in 1800 – the voltaic pile. It consisted of a stack of zinc and copper plates with brine-soaked paper disks in between. This battery was able to produce a steady electric current for quite some time.

Volta, however, did not know that the chemical reactions created the voltage. He mistakenly thought that the battery’s cells had an everlasting supply of energy. The battery would run out of juice due to corrosion, he thought.

In 1836, John Frederic Daniell, a British chemist, created the first practical battery. It became an industry standard and was used extensively by electrical telegraph networks.

Since those early days, battery technology has advanced significantly. What will we be using in one-hundred years’ time as a portable source of electrical energy? Maybe we will have gadgets that capture and release energy from the sun, their surroundings, friction, or something completely new.
