The first patent describing the concept of an electrochemical capacitor was filed in 1957 by Becker 9, who used carbon with a high specific surface area (SSA) coated on a metallic …
From the mid 18th century on, before there were batteries, experimenters used Leyden jars to store electrical charge. As an early form of capacitor, Leyden jars, unlike electrochemical cells, stored their charge physically and would release it all at once.Many experimenters took to hooking several Leyden jars together to create a stronger charge and one of them, the …

force is produced when a high voltage is applied to many other asymmetrical capacitors as well. Brown received multiple patents in the U.S. and one in Great Britain for his work 1, 2, 3. This effect is called the Biefeld-Brown Effect; it was discovered while T. T. Brown was in graduate school, working under his advisor, Dr. Paul Alfred Biefeld.

Natural capacitors have existed since prehistoric times. The most common example of natural capacitance are the static charges accumulated between clouds in the sky and the surface of the Earth, where the air between them serves as the dielectric. This results in bolts of lightning when the breakdown voltage of the air is exceeded.

One of the first products which emerged from this effort was the Fail-Safe Capacitor, which received United States Patent No. 3,792,323. This capacitor was used in special circuitry in television sets to disrupt the high voltage to the picture tube so that there would be no excess (dangerous) radiation emitted.

Boykin earned his first patent in 1959 for a wire precision resistor, which allowed for the designation of a precise amount of resistance for a specific purpose. This was followed by his 1961 patent for an electrical resistor that was both inexpensive and easy to produce. ... He created an electrical capacitor in 1965 and an electrical ...
When Nikola Tesla filed the first patent for a vacuum capacitor on September 15, 1896 - 125 years ago - little did he know the impact this invention would have on today''s modern world. Becoming the father of …
After Becker, Sohio Corporation, Cleveland, in the year 1969, manufactured the first electric double layer capacitor for the commercial purpose using porous carbon in a non-aqueous solvent comprising tetra alkyl ammonium salt based electrolyte (Boos 1970). In 1978, NEC (a Japanese multinational Information Technology …
