JEOL Announces Premlis, a New Supercapacitor
JEOL Ltd. (JEOL; Yoshiyasu Harada, President) and Advanced Capacitor
Premlis is a new asymmetrical capacitor using JEOL's proprietary nano
gate carbon (NGC®) for the cathode and graphite carbon
for the anode. It features a higher voltage level and enhanced energy
density, both of which are essential properties of capacitors.
Premlis was tested for safety by KRI Corporation, an independent organization, in 4 different areas: short circuit, nail penetration, overcharge, and overheating. No explosion or fire was reported in any of the tests, assuring the safety of the capacitor.
ACT plans to distribute samples of Premlis in different sizes to users in a variety of fields for their review. These samples will be produced in the in-house prototype manufacturing facilities in operation since April 2006. ACT will also seek feedback from users in developing cells with an effective energy density of 20 Wh/kg or higher suitable for energy storage with solar photovoltaic system, fuel cells, and so on.
While working together with Nissan Diesel Motor Co., Ltd. to produce a commercial model of EcoCache®, a symmetrical capacitor, ACT will look for a new business partner for the new capacitor, Premlis, and promote these two models, EcoCache® and Premlis.
*Sample specifications are subject to change without notice due to modification.
Note 1: Effective energy density: The effective capacity of an electric double layer capacitor rated 3 V is 75% of the total capacity because the voltage used is charged and discharged in a range from 3 V to 1.5V.
