Abstract
(EN)
This thin battery includes a sheet-form electrode group and an outer case housing the electrode group, wherein the electrode group contains a positive electrode, a negative electrode, and an electrolyte layer interposed between the positive and negative electrodes, and there is a lubricating substance with a lubricating action interposed between the electrode group and the inner surface of the outer case. The lubricating substance may be for example an inert gas. The inert gas may for example contain at least one of nitrogen and argon. The lubricating substance is ideally at least present between the end surfaces of the electrode group on both sides in the thickness direction and the main flat surfaces of the inner surface of the outer case facing said end surfaces.

L'invention concerne un accumulateur mince comprenant un groupe d'électrodes en forme de feuille et un boîtier extérieur qui abrite le groupe d'électrodes. Le groupe d'électrodes comprend une électrode positive, une électrode négative et une couche d'électrolyte interposée entre les électrodes positive et négative. Une substance lubrifiante assurant une action de lubrification est interposée entre le groupe d'électrodes et la surface intérieure du boîtier extérieur. La substance lubrifiante peut être par exemple un gaz inerte. Le gaz inerte peut par exemple contenir au moins de l'azote ou de l'argon. Idéalement, la substance lubrifiante est au moins présente entre les surfaces d'extrémité du groupe d'électrodes, sur les deux faces dans la direction de l'épaisseur et sur les surfaces plates principales de la surface intérieure du boîtier extérieur qui font face à ces surfaces d'extrémité.
