When was a supercapacitor invented?

However, while the aluminium electrolytic capacitor was used industrially from 1892 and manufactured using the technology known today from 1931 onwards, the supercapacitor was forgotten for many years: It was not until 1957 that the first patents on “capacitors with porous carbon electrodes” were granted.

How does a super capacitor work?

Unlike batteries or accumulators, supercapacitors do not supply a chemically determined voltage that is constant over a longer period of time and only drops rapidly at the end of discharge, but, like any capacitor, a voltage that sinks linearly with a constant current draw.

When were electrolytic capacitors discovered?

The principles of electrolytic capacitors and supercapacitors were discovered at comparable times – in 1875 by Eugène Adrien Ducretet (electrolytic capacitor) and already in 1853 by Hermann von Helmholtz (supercapacitor), with Helmholtz defining the double layer effect in 1879.

Who invented the PRI Ultracapacitor?

In 1982, the Pinnacle Research Institute developed capacities over 1000 F with low internal resistances for military purposes as the “PRI Ultracapacitor”. From 1992, Maxwell continued this development and its marketing. By the end of the 1990s, other innovative manufacturers such as Cooper Bussmann/Powerstor (now Eaton) joined the efforts.
