Abstract:
A method of making a double layer capacitor comprising the steps of:impregnating an activated carbon fiber preform with an evenly distributed and continuous path of aluminum, thereby forming an aluminum impregnated carbon fiber preform;bonding a current collector plate on a surface of said aluminum impregnated carbon fiber preform;aligning a pair of aluminum impregnated carbon fiber preforms having been bonded to a respective current collector plate together, wherein said pair of aluminum impregnated carbon fiber preforms have non-bonded surfaces facing one another;placing an ionically conductive separator between said facing surfaces of said pair of aluminum impregnated carbon fiber preforms; andsaturating said pair of aluminum impregnated carbon fiber preforms and said ionically conductive separator with an electrolyte solution.
