Battery

An electrochemical cell includes an electrode assembly including a plurality of electrodes; an exterior material including an accommodating part that accommodates the electrode assembly and a ealing part that seals the electrode assembly by bonding sealing surfaces along edges of the accommodating part; and an electrode lead connected to the electrode assembly and extended to be exposed to an outside, wherein the accommodating part includes a concavo-convex pattern extended in on one direction and disposed in a direction intersecting with the one direction, and at least a part of the concavo-convex pattern includes an adjacent portion that forms a boundary line in contact with the sealing part at an end portion in the one direction.

Electrochemical cell and exterior material provided therein

Electrode plate

The present invention relates to an iontophoresis patch integrated with a battery, more specifically to an iontophoresis patch integrated with a battery which adopts the principle of iontophoresis as a means for infiltrating a substance of interest such as a medication or a cosmetic substance into skin. The iontophoresis patch of the invention comprises: a variable-shape substrate; a first electroconductive layer coming into contact with the substrate; a first electrode layer coming into contact with a part of the first electroconductive layer; a second electroconductive layer which comes into contact with the substrate and which is disposed on the same as the first electroconductive layer; a collector coming into contact with the second electroconductive layer; an electroconductive adhesive coming into contact with the second electroconductive layer and with the collector; a second electrode layer coming into contact with the collector and having a polarity opposite to that of the first electrode layer; an ion-conductive polymer electrolyte disposed between the first electrode layer and the second electrode layer; and an adhesive for sealing the ion-conductive polymer electrolyte.
