Energy density of this capacitor reaches 10 times that or more of the high energy capacitor which exists.
The nano- as for gate * capacitor, charging and time quite is short, while it possesses the capacitor original advantage such that life is very long, the nickel - it exceeds the hydrogen electric battery, the large-sized lithium - the high energy which is approached to the ion electric battery - it has possessed density. As for the accumulation of electricity system which uses the nano- gate * capacitor, for example, the hybrid automobile and the electric automobile, being something which makes the utilization of the buffer of solar optical generation of electricity and wind force generation of electricity and the extensive product of the accumulation of electricity warehouse and the like of nighttime electric power possible, energy problem of the world, being something which it can contribute largely for the environmental problem solving, it does.
Background * merit of development
1. Accumulator and superiority or inferiority of capacitor
Electricity is stored and presently the accumulator which stores electricity with the chemical reaction like the ion electric battery with the lead electric battery as beginning, the nickel hydrogen electric battery and the lithium - has formed main current as power source as the element which it uses. This accumulator, electrical energy - chemical energy - converting with the chemical reaction, because cycle life of thing and charging and whose charge time is long from the fact that it is the system which you store, with the time when it requires for the chemical reaction, is short, has had the fault such that often exchange of the electric battery becomes necessary. In addition, the harmful matter is included by most accumulators, also influence to the environment which accompanies the abolition of the accumulator where life comes is large. In addition, to the present typical accumulator doubt is thrown to the safety.
In comparison with this kind of accumulator, because as for the capacitor electricity is stored energy - without conversion while it is electricity, charge time becoming extremely short, in addition, also cycle life theoretically becomes semipermanent. Furthermore, as for the component of the capacitor, the majority is the charcoal and the ± Ù Ð foil, also influence to the environment which accompanies abolition to be considerable decreases. Furthermore, as for the capacitor as for that kind of phenomenon it does not happen completely vis-a-vis the accumulator which has the possibility of exploding overcharge and with strong impact, emitting the fire, has possessed high safety.
However, the largest weak point of the capacitor energy - density quite was low thing in comparison with the accumulator, that for the sake of, as an accumulation of electricity element as for thinking of utilization almost was not to 10 years ago.
2. Development of electronic circuit technology for effective utilization of capacitor
If the Okamura œN husband person of the former technical advisor of the JOEL, Ltd. ((inc.) the Okamura laboratory Chief Executive Officer) the technical idea which was thought (efficiency improvement of 4 times is achieved with electronic circuit technology and efficiency improvement of 5 times is achieved with the capacitor, it can store the electricity of 20 times with multiplication.) Of on the basis, Okamura did many invention, efficiency improvement of substantial 4 time was achieved by the electronic circuit technology which is based on those inventions, fundamental technology in order to use the capacitor as the accumulation of electricity element was established. Furthermore, many of those inventions patent are applied with the JOEL, Ltd., and joint ownership presently to right are converted one after another.
3. Present condition of utilization of capacitor accumulation of electricity system
The accumulation of electricity system which combines the capacitor and the electronic circuit which it mentions, leading the world, from research and development stage started being offered by utility in Japan. Finger month electrical machinery and appliances? Bullhead Í capacitor non power failure power source in November of 2001 commercialization, the Nissan Diesel Motor Co., Ltd.? Bullhead Í capacitor * hybrid * track/truck in June of 2002 commercialization, Honda Motor Co., Ltd.? The bullhead Í fuel cell and the hybrid car FCX of the capacitor it commercializes in December of 2002, does sale respectively.
4. In the JOEL, Ltd. research * development of efficiency improvement of the capacitor
The JOEL, Ltd. energy of the capacitor which becomes largest theme after the electronic circuit technical establishing - focusing on density improvement, promoted research, this time, energy - density 50 - the 75wh / kg the epoch-making capacitor (the nano- gate * capacitor) succeeded in development.
This energy - density the nickel - energy of the hydrogen electric battery - exceeds the density 60Wh / kg, the large-sized lithium - energy of the ion electric battery - it is something which is approached to the density 120Wh / kg, it is something which the largest weak point of the capacitor solution is decided. Furthermore, above-mentioned energy density is not something which is based on false capacity, the carbon by the non- porous charcoal - is something by the pure electric double layer capacitor of the carbon.
The JOEL, Ltd. concerning this development technology completes basic patent application already, in addition, have decided to do foreign application in the range where in the future the world is wide.
The high energy which eradicates the fault of the accumulator this the high energy which was developed - by combining the nano- with gate * capacitor and Okamura's invention of density, - it means that the accumulation of electricity system of density is completed. Namely, the nano- gate * capacitor the high energy which is a match to the accumulator - is density has had also the capacitor original character such that cycle life of thing and charging and whose charge time is short in spite, is long.
5. Uses the nano- gate * capacitor of the JOEL, Ltd. development the market of the product which High energy - to, the former capacitor compared to extensive, most markets of the accumulator are covered from large output. Extremely portion of the market is listed next.

6. Energy of the world contribution to - * environmental problem
As for electricity the recognition which we assume it is not accumulated, open and from the presently it passes, becomes the opportunity which exuviates. Necessary electric power the necessary quantity, can be utilized efficiently at necessary size. With application to traffic of the automobile and the like, the decrease effect of substantial improvement and pollution of fuel economy is proven with the capacitor * hybrid * track/truck which is already sold.
In electrical field, replacing to power generation with pumped-up water, making use of the accumulation of electricity system the nano- by gate * capacitor, in addition, if it utilizes in load leveling, the high efficiency and long-lived, in safety, energy of the world - and you can expect to environmental problem big contribution. Furthermore, assuming, life came to the capacitor temporarily, the harmful matter is not included by the capacitor unlike the accumulator, also the cost which accompanies disposal decreases considerable, either adverse effect to environment almost does not occur.
7. Handling the development technology of the JOEL, Ltd.
The JOEL, Ltd. is the special manufacturer of the science study equipment which begins the electron microscope, we have not possessed the manufacturing technology of the mass production item.
