Title:

NONAQUEOUS ELECTROLYTE POWER STORAGE ELEMENT

Document Type and Number:

Japanese Patent JP2023102110

Kind Code:

A

Abstract:

To provide a nonaqueous electrolyte power storage element having both excellent heat dissipation property and excellent insulation property of an electrode body.SOLUTION: A nonaqueous electrolyte power storage element comprises: an electrode 1 including a positive electrode 8, a negative electrode 9 and a separator 10 including a resin substrate layer 11; and a container 2 in which the electrode body 1 is stored. Heat conductivity of a member forming the container 2 is 10 W/m K or more and 50 W/m K or less. The electrode body 1 includes an outermost part 13 formed from the separators 10 laminated single, double or more not including the positive electrode 8 and the negative electrode 9. A total average thickness of the substrate layer 11 in the outermost part 13 is 0.015 mm or more and 0.045 mm or less.SELECTED DRAWING: Figure 3
