JEOL Ltd. (Gon’emon Kurihara, President) and Advanced Capacitor Technologies Inc. (ACT; Toru Usami, President) will begin commercial production of the Premlis series supercapacitors with improved features including internal resistance in November 2008.

ACT has been distributing samples of Premlis with an effective energy density of 15 Wh/kg on a cell basis since the company announced the product in September 2006 to explore its applications. During this period, ACT continued improving the cell energy density of 20 Wh/kg to 30 Wh/kg, and received a number of favorable reviews and requests for volume production.

ACT will offer in stages 3 cell capacitors including Premlis A5000, and 2 module capacitors including Capacitor Battery. These models have superior internal resistance and low temperature properties in response to requests from the sample users. Premlis A5000, in particular, features the world highest level of effective energy density, 5 times higher than many double layer capacitors. While the current production volume is still limited, ACT plans to implement a larger production line in 2009 to manufacture 20,000 units monthly.

Target applications include independent power supplies utilizing reusable energies such as solar power, emergency power supplies such as UPS, and portable equipment power supplies for its rapid, safe charging capability. As a charge system for solar power generation, the supercapacitor lasts longer than secondary cells such as lead battery subject to chemical reaction, and is being integrated in long lasting solar panels for commercial application. In this field, panel lights combining solar panels, LED, and Premlis A5000 are winning approval, and some local government bodies are seriously considering its use.Solar panels, LED, and capacitor all have an expected life of 10 years or longer. Production and maintenance costs of these panel lights have been reduced to the level of conventional products by making it easy to combine the components and replace batteries.

ACT will continue exploring business possibilities, and develop products to meet 1 wide range of applications including recycled energies.
