Embodiment 1

[0112] As the exterior material of the battery, a stainless steel airtight can with a polyphenylene sulfide gasket attached to an open end and a stainless steel exterior can were prepared. The negative electrode was crimped on the inner surface of the airtight can, and two separators punched into a circular shape with a diameter of 19 mm were laminated on the negative electrode, and then the positive electrode was laminated on the separator. A stack of negative electrode / separator / positive electrode was placed in a sealed can. Next, inject the non-aqueous electrolytic solution into the airtight can, absorb the liquid into the diaphragm, cover the outer can, and seal it by fastening it to obtain figure 1 A coin-shaped non-aqueous electrolyte battery with a diameter of 20 mm and a height of 3.2 mm of the structure shown.

Embodiment 2

[0116] A coin-shaped non-aqueous electrolyte battery was obtained in the same manner as in Example 1, except that one sheet of the separator of Production Example 2 punched out into a circle was used for assembling the battery.

Embodiment 3

[0118] A coin-shaped non-aqueous electrolyte battery was obtained in the same manner as in Example 1, except that one sheet of the separator of Production Example 3 punched out into a circle was used for assembling the battery.

Abstract

This non-aqueous electrolyte battery is provided with: a positive electrode; a negative electrode; a separator; and a non-aqueous electrolyte, wherein the separator includes 50-85 mass% of a polyphenylene sulfide fiber, 10-30 mass% of an aramid fiber, and 5-35 mass% of a cellulose fiber. Thereby, the present invention can provide a non-aqueous electrolyte battery in which degradation in propertiesin a high-temperature environment is suppressed and defects during assembling less occurs.

Description

technical field [0001] The present invention relates to a non-aqueous electrolyte battery that exhibits little deterioration in characteristics in a high-temperature environment and that causes few failures during assembly, and a separator capable of manufacturing the non-aqueous electrolyte battery. Background technique [0002] Non-aqueous electrolyte batteries are used in various applications by utilizing their characteristics such as high capacity and high voltage. In addition, non-aqueous electrolyte batteries are required to improve various characteristics along with the expansion of their application fields. [0003] In particular, in recent years, with the practical use of electric vehicles, the demand for non-aqueous electrolyte batteries (secondary batteries) for vehicles has been increasing, and they are mainly used as drive power sources for electric vehicle motors. other applications. For example, development of an emergency notification system for notifying i...
