When was the battery invented?

The invention of the electronic valve in the early 1900s formed the significant next step towards high technology, enabling frequency oscillators, signal amplification and digital switching. This led to radio broadcasting in the 1920s and the first digital computer called ENIAC in 1946.

The discovery of the transistor in 1947 paved the way to the integrated circuit 10 years later. The microprocessor ushered in the information age and revolutionised the way we live today.

Humanity depends on electricity, and with increased mobility, people are moving more and more towards portable power storage – first for wheeled applications, then portability and finally wearable use.

As awkward and unreliable as the early batteries may have been, future generations may look at today’s technologies as nothing more than clumsy experiments.
