Definitions
- the charging layer disposed between the opposing electrodes is thin, so the stress due to the cut acts and the electrode deforms.
- the electrode contacts the other electrode and short-circuits particularly at the end face.
- Quantum batteries having such a basic configuration can be arranged as a battery by attaching electrode terminals to the electrode layer as needed, or attaching exterior members, covering members, and the like around them.
- the basic configuration of the quantum battery may be a single-layer battery, and the single-layer batteries may be stacked and connected in series or in parallel to be packaged.
- a quantum battery as a single-layer battery can be folded or folded in a bellows shape, and a plurality of single-layer batteries can be stacked and connected in series or in parallel to be packaged.
- both side edges in the width direction of the sheet battery 1 are formed in parallel to each other.
- the width of the sheet-like battery 1 is not particularly limited.
- the width can be about 10 mm to 500 mm.
- the length of the sheet-like battery 1 in the longitudinal direction (that is, the direction perpendicular to the width direction on the same surface) is such that the sheet-like battery 1 is bent once and the positive electrode layers 2 (or the negative electrode layers 3) of the sheet-like battery 1 are The length is not particularly limited as long as the length can be overlapped, and can be, for example, about 10 mm to 100 m.
- the thickness of the charging layer 6 of the sheet battery 1 is thin, physical force acts during cutting, and the electrode layers (the positive electrode layer 2 and the negative electrode layer 3) move due to stress, and cutting.
- the positive electrode layer 2 and the negative electrode layer 3 come into contact with each other at the end face of the sheet-like battery 1 that has been subjected to, and a short circuit may occur.
- the occurrence of a short circuit due to contact between the positive electrode layer 2 and the negative electrode layer 3 will be abbreviated as “metal sag short” and will be described below.
- each groove part 5 in the cross section along the longitudinal direction of the sheet-like battery 1 is such that the length in the film thickness direction of each groove part 5 is the film thickness of the positive electrode layer 2 (or the negative electrode layer 3) and the charging layer 6. It is about the same length as the total length of each length.
- the width of the opening of each groove 5 in the positive electrode layer 2 (or the negative electrode layer 3) is greater than the width of the bottom of the groove 5 reaching the charging layer 6. Too long.
- the width of the laser beam is set to be relatively small.
- the charging layer 6 under the positive electrode layer 2 is narrowed, and the charging layer 6 is irradiated with laser light to cut the thickness direction of the charging layer 6.
- the positive electrode layer 2 of the sheet battery 1 is irradiated with laser light to form the positive electrode layer groove portion.
- the negative electrode layer 3 of the sheet battery 1 is irradiated with laser light to form a negative electrode layer groove in the film thickness direction.
- each position of the positive electrode layer groove portion and the negative electrode layer groove portion is a position not facing the charging layer 6 (that is, a non-facing position). It is formed alternately.
- each positive electrode layer groove portion and each negative electrode layer groove portion can function as a folding portion that is a reference for a position to be folded.
- battery test includes battery performance evaluation, battery normality inspection, battery performance measurement and test, for example, battery performance inspection, charge / discharge test, conditioning, charge / discharge cycle test, This concept includes an aging test and the like.

Abstract
Le problème décrit par la présente invention est de permettre la formation d'une pluralité de batteries ayant une forme arbitrairement définie à partir d'une batterie en forme de feuille dans laquelle une couche de charge est prise en sandwich entre une couche de pôle positif et une couche de pôle négatif, de façon à être réalisée facilement et à éviter un court-circuit venant de l'affaissement de métal. La solution selon la présente invention porte sur une batterie en forme de feuille qui est une batterie secondaire en forme de feuille comprenant une couche de pôle positif, une couche de pôle négatif, et une couche de charge interposée entre celles-ci, et qui est caractérisée en ce que la couche de pôle positif, qui est formée sur une surface de la couche de charge, et/ou la couche de pôle négatif, qui est formée sur l'autre surface comprennent une pluralité de parties de rainure formées par retrait dans une direction d'épaisseur de film, et une pluralité de petites batteries segmentées par la pluralité de parties de rainure.
