二次電池である。2. Description of the Related Art In recent years, electronic devices such as a portable radio telephone, a portable personal computer, and a portable video camera have been developed, and various electronic devices have been reduced in size to be portable. Along with this, a battery having a high energy density and a light weight is also adopted as a built-in battery. A typical battery that satisfies such requirements is a lithium-based metal such as lithium metal, a lithium alloy, and lithium ions, and an aprotic organic solvent in which a lithium salt such as LiCIO 4 or LiPF 6 is dissolved. This is a lithium secondary battery using a solvent as an electrolyte.

９−２１３２８５４号）。[0003] In the case of equipment using a battery as a power source as well as a lithium battery, the demand for weight reduction and miniaturization of the whole equipment has not been exhausted. Therefore, if the battery performance is the same, the lighter and the smaller, the more the user is preferred. In recent years, in order to satisfy this demand, a case in which a metal resin laminated film is formed in a flat bag shape has been proposed as a case for accommodating power generation elements such as electrodes, separators, and electrolytes (for example, JP-A-9-213854). ).

フィルムを電池ケースとして使用した場合、従来の厚く

か、機器に装着するまで電池に外部応力が加わらないよ
うに神経を使わなければならなかった。それ故、本発明
の目的は、金属樹脂積層フィルムを電池ケースとする短
絡しにくい電池を提供することにある。However, when a metal resin laminated film is used as a battery case, it tends to be elastically deformed by external stress as compared with a conventional case made of a thick and hard material. Therefore, the stress is transmitted to the power generation element via the case, and a short circuit is likely to occur. For this reason, the battery case must be placed in another protective container to complete the battery, or a nerve must be used so that no external stress is applied to the battery until it is mounted on the device. Therefore, an object of the present invention is to provide a battery that is unlikely to be short-circuited using a metal resin laminated film as a battery case.

するカバーを有することを特徴とする。In order to achieve the above object, a battery according to the present invention comprises a power generating element having a separator for preventing a short circuit between a positive electrode, a negative electrode, and a positive and negative electrode, and a metal resin for housing the power generating element. In a battery including a laminated film case, an end of the power generating element is provided with a cover for preventing stress deformation of the end.

絡しやすい。[0006] In the power generating element, since the separator is interposed between the positive electrode and the negative electrode, a short circuit does not occur even when stress is applied to most of the portions. The separator is not limited to a plate-like member simply for preventing a short circuit, but may also serve as a polymer electrolyte containing an electrolyte or an inorganic solid electrolyte. However, at the end where the separator is interrupted, stress may cause one of the poles to go around the other, or the separator may be elastically deformed and short-circuited. For example, when the current collector of the electrode plate is formed of a metal foil or a metal resin laminate film, such as a lithium battery, and the separator is also formed of a thin film, and the stacked body is used as a power generation element. When a spirally wound coil is used as a power generating element at the end of the laminated body, a short circuit is likely to occur at the end in the winding axis direction.

発電要素の端部に被せやすいものが好ましい。According to the battery having this feature, even if an external stress is applied to the battery, the end of the power generating element is covered with the cover, so that it is difficult to cause a short circuit. The cover is made of an insulating material, such as polypropylene (PP) or polyethylene (PE), which is easy to mold and is stable with respect to the battery structure such as an electrolyte. The size and shape are not limited, but those that are less likely to deform themselves than the power generating element and that are easy to cover the end of the power generating element such that a cap is put on the head are preferable.
