Document Type and Number:

Japanese Patent JP2022145552

Kind Code:

A

Abstract:

To provide a laminate for a nonaqueous electrolyte secondary battery enhanced in the effect of preventing short circuit by controlling the shape of dendrite.SOLUTION: A laminate for a nonaqueous electrolyte secondary battery comprises a separator and a graphite anode. In the laminate, the graphite anode has a nonreactive parameter of 230% or more; the average value of pore volumes is 0.015 μm3 or less when a microscope image of the surface of the separator opposed to the graphite anode is analyzed.SELECTED DRAWING: None
