NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY CELL AND ASSEMBLED BATTERY USING SAME

Document Type and Number:

WIPO Patent Application WO/2017/082399

Kind Code:

A1

Abstract:

[Problem] To provide a non-aqueous electrolyte secondary battery cell in which a safety measure is taken and with which the energy density can be increased, and an assembled battery in which the cell is used. [Solution] The cell itself is shaped as a rounded square tube. A core material 5 for preventing electrolyte permeation is provided at the center of the cell, the core member 5 being a hollow cylindrical insulator having a square cross-section. A cell monitoring system such as a temperature sensor 12 is provided in the hollow part of the core material 5. A cell base member comprising a positive electrode member, a separator, and a negative electrode member of a non-aqueous electrolyte secondary battery is wound around the core material 5. Terminals 1, 2 made of an electroconductive metal electrically connected to the collector of the positive electrode member or the collector of the negative electrode member are provided so as to be exposed to the exterior of the cell. The temperature sensor 12 is attached to the center part of the hollow part of the core material 5 so as to be in close contact with the core material 5.
