Fuji Heavy Industries lithium ion capacitor (Dra) through the improvement of the electrode structure and composition, Meanwhile, as with lithium-ion rechargeable batteries and electric double layer capacitors achieve the dual characteristics of the battery. Comparable with the electric double layer capacitors not only get the current output. such as lithium-ion rechargeable batteries but can also ensure that a higher energy density. If applied to hybrid, is expected to lower fuel consumption. Reportedly now include automobile manufacturers to provide a sample of enterprises, "a very high evaluation of the samples, Manufacturers reacted particularly well. " Fuji Heavy Industries plans to Dra capacitor technology to authorized manufacturers commissioned for production. The basic principle is to allow the use of such capacitors many auto manufacturers to increase supply capacity, the realization of price cuts. Currently working to expand the scope of the manufacturers support the technology. Charge-discharge cycle life has been extended, a high-capacity capacitor design. For example, the dimensions of 135mm x 103mm x 10mm, 246g heavy capacitors, the 4400F capacity (2400mAh). Its energy density, the unit weight of 30Wh/kg, the unit volume of 52Wh/l. greatly exceeding the original electric double layer capacitors.
