Electric double layer capacitor, electrolyte battery and method for manufacturing the same

A method for manufacturing an electrolyte battery, comprising a cell in which a pair of active material bodies, which are impregnated with an electrolyte, are disposed in opposition on either side of a separator;

• the active material bodies being provided with collector electrodes, a peripheral portion of the cell being sealed by a sealing member composed of synthetic resin;
• and the sealing member being formed by abutting two case halves;
• the method comprising:
• a process step of providing at least one long slit in the collector electrodes;
• a process step which is a process step of forming the case halves formed by insert molding on the collector electrodes and filling the slit, the case halves comprising a recess, one side of which extends in the lengthwise direction of the slit and, the cell being fitted into a portion inward from the slit;
• and
• a step of joining the case halves by abutting the case halves and applying ultrasonic vibration either in a perpendicular direction or a diagonal direction with respect to the lengthwise direction of the slit.

An electric double layer capacitor, comprising:

• a cell in which a pair of polarizable electrodes, which are impregnated with an electrolyte, are disposed in opposition on either side of a separator;
• wherein the polarizable electrodes are provided with collector electrodes and a peripheral portion of the cell is sealed by a sealing member composed of synthetic resin;
• wherein the sealing member is formed by abutting two case halves;
• wherein the case halves are each provided with a recess into which the cell is fitted;
• and
• wherein a slit filled with the resin constituting the sealing member is provided in opposition to a peripheral portion of the recess in each of the collector electrodes.
