Super-capacitor energy storage sector, technology has begun to emerge recruits
So far, the industry agreed that the lithium-ion batteries Laptop Battery for electric cars is still the main way of energy reserves, but now have several companies began to consider using a super capacitor (ultracapacitor) lithium-ion battery products as a good additional equipment. South Korea will be an electronics company Neescap Tuesday claimed that 9 million U.S. dollars will be invested to expand its transportation, electric power systems and consumer electronics products with super capacitor (ultracapacitor) the product capacity.
In the U.S., capable of product design and manufacture of super-capacitor and electrolyte materials, required for companies Graphene Energy, EnerG2 and Ioxus 3. Another one EEStor companies by the venture capital firm Kleiner Perkins Caufield & Byers as the background, now the company has signed an electric car company Zenn super-capacitor supply Hp Pavilion DV1000 battery(Hp dv1000 battery) agreement.
The more traditional batteries, super capacitors can store the electricity not much. So at home Rechargeable (Plug-in) electric vehicles, such a capacitor can not serve as power supply equipment alone, but need to used in conjunction with fuel cells. On the other hand, the super capacitor is also equipped with faster diarrhea release energy stored in capability. In addition, this capacitor charging time is very short, only takes a few seconds or minutes of time will be able to complete the charge, but charge several times the performance there will not be reduced.
Capacitor current consumer electronics products have been Hp PF723A battery used in digital cameras and other occasions, in order to flash this need momentary high-energy input of the device provides energy supply. According to experts, super capacitor the key issues facing the future is how to increase the operating voltage of this capacitor so that it can be in the high-voltage environment.
According to Ioxus engineers said, the super capacitor is environmentally friendly energy, a good supplement can make batteries, fuel cells, solar or wind power generation, power supply would be more perfect. At the same time the capacitor used in the production of materials are also very environmentally friendly, the price some are more readily accepted.
Super capacitor technology, the future development direction:
Massachusetts Institute of Technology computer electronics engineer Joel Schindall said that in the next few years, the super capacitor energy storage capacity will be a qualitative leap. The current super capacitor product discharge rate is 10 times that of traditional batteries, while the energy storage capacity in the volume under the same conditions, only Hp 367759-001 battery the latter 5%.
He said: "super-capacitor charge and discharge operations of certain frequent use of a great occasion, such as Brake Energy Recovery-type brake system (that is, five sets of F1 shows on CCAV all day nagging what Coles host system), This capacitance is very easy to use. Of course, this product is currently not yet a large scale to replace the batteries. "
Over the past five years, Schindall led research team has been studying the super capacitor in the energy storage component - porous carbon material, replaced with another carbon nanotube conductive matrix material + energy storage component. Earlier this year, they also set up a FastCap this company in order to the commercialization of research results.
Schindall said the super capacitor energy storage capacity Hp PM579A battery of the product will eventually reach about 25% of the battery. At present, out of Massachusetts Institute of Technology developed nano-materials, energy storage capacity has reached twice the level of carbon materials. The next few months, he led the research team will be showing the kind of energy storage capacity is five times more activated carbon products.
