- In 1740, Ewald Georg von Kleist constructed the first capacitor.
- In the same year Pieter von Musschenboek invented the Leyden Jar.
- Ben Franklin soon found out a flat piece of glass can be used in place of the jar model.
- The Electric Double Layer Capacitor effect was first noticed in 1957 by General Electric.
- Standard Oil of Ohio re-discovered this effect in 1966.
- Standard Oil of Ohio gave the licensing to NEC, which in 1978 marketed the product as a “supercapacitor”.

Some example of improving efficiency with using supercapacitors
Rockster R1100DE hybrid rock crusher
Power peaks are smooth by supercapacitors.
The fuel consumption is reduced and through the use of virtually maintenance-free electric motors also maintenance costs are minimized.
With this technology you can save up to 16,000 liters (20,800$ if Diesel = $1.30 /ltr) of diesel annually.
