Secondary cell module and method of its production

摘要

This invention relates to a secondary cell module and the method of its production, in which it is composed of a combination cell formed by the positive electrode terminal and/or the negative electrode terminal of multiple secondary cells are connected in series and/or in parallel with each other through a metal bus-bar and a casing which contains this combination cell, and the above secondary cell is formed in a sheet shape and is composed of sheet-type internal electrode couple, electrolytic solution and a flexible outer wrapper of envelope type which contains these internal electrode couple and electrolytic solution in a sealed state. The secondary cell module under this invention is of a simple structure and it can be small-sized and light-weighted or thin-shaped as necessary and the heat which generates inside the cell can be efficiently diffused to outside, thereby enabling the production of cells of high capacity with a high degree of freedom in designing its shape as well as supreme productivity.
