<p>The present invention provides a non-aqueous battery having a unit cell laminate, which comprises a positive plate with an active material of positive electrode only on a single face of a collector foil, a negative plate with an active material of negative electrode only on a single face of a collector foil, and a separator, arranged in a battery casing, wherein the single face of the positive plate with the active material of positive electrode and the single face of the negative plate with the active material of negative electrode are arranged to face each other across the separator, and the other face of the positive plate without the active material of positive electrode and the other face of the negative plate with the active material of negative electrode are arranged to face each other across an insulating film. The structure of the present invention can effectively prevent an abrupt increase in internal temperature even when a short circuit occurs between an active material of positive electrode and a negative electrode due to external application of an abnormal heat, a crush of the battery in a heaping direction, or a pierced nail, thereby ensuring the safety of the battery. <IMAGE></p> |
