MANUFACTURE OF INTEGRATED ELECTRODE FOR ELECTRIC DOUBLE-LAYER CAPACITOR

摘要

PROBLEM TO BE SOLVED: To improve the productivity of a laminated electric double-layer capacitor by producing an integrated electrode composed of a metal-made collecting electrode and polar electrode used as a positive and negative electrodes of this capacitor with the less number of steps than that of the prior art. SOLUTION: An active carbon powder is kneaded with at least a binder added thereto to prepare a kneaded material for forming a polar electrode. This material is thrown by specified amount in a die 4 to form a first kneaded material layer 1, a mesh-like metalmade collecting electrode 11 is laid thereon, that kneaded material is thrown by a specified amt. thereon to form a second kneaded material layer 2. The layers are compression-formed by a press 3 to bury the collecting electrode 11 in the polar layer with collecting electrode leads 11a led outside to form an integrated electrode.
