POWER STORAGE PACKAGE STRUCTURE, ELECTROCHEMICAL DEVICE, AND ELECTROCHEMICAL MODULE

摘要

PROBLEM TO BE SOLVED: To provide an electrochemical device which has high energy density and reduces the size.

SOLUTION: A power storage package structure 20 of this invention includes a frame like part (a lower frame part 202 and an upper frame part 203) formed by a pair of insulators which face each other across a bonding surface, a lid attached to an opening of the frame like part and forming a sealed structure, and an extraction electrode 204 formed on an outer wall of at least one of the pair of frame like parts. Electric power is supplied easily from the extraction electrode 204 by attaching an electrode structure of the power storage package structure. Therefore, a highly efficient electrochemical device is obtained.
