Abstract
This invention relates to electric double layer capacitor utilizing electric double layer formed at interface between polarizable electrode and electrolyte, and carbon fibers or activated carbon fibers are used as polarizable electrode (17), and on the polarizable electrodes (17) consisting of the carbon fibers or activated carbon fibers conductive electrodes (18) as collectors are formed to constitute electrode parts.
Claims22
An electric double layer capacitor having an electric double layer formed at an interface between a polarizable electrode and an electrolyte, wherein said polarizable electrode consists of carbon fibers or activated carbon fibers, a conductive electrode formed on one face of said polarizable electrode and an opposing electrode disposed on the other side of said polarizable electrode with said electrolyte inbetween.
A multiunit capacitor element having an electric double layer formed at an interface between a polarizable electrode and an electrolyte, wherein said polarizable electrode consists of carbon fibers or activated carbon fibers with a conductive electrode formed on one face thereof, each unit capacitor element prepared by laminating said polarizable electrode such that margin parts are formed on both ends with a separator soaked with electrolyte inbetween, a plurality of said unit capacitor elements are laminated together and electrodes for outside leading out are formed on both ends of this laminated body.
