Nonaqueous electrolyte secondary battery

摘要

Disclosed is a nonaqueous electrolyte secondary battery comprises a sealing unit including a conductive support plate, wherein the conductive support plate contains at least one kind of a conductive material selected from the group consisting of a metal, an alloy and a composite metallic material, each of the metal, the alloy and the composite metallic material has a modulus of elasticity (Young's modulus) at 25° C. that falls within a range from 1x10¹¹ Pa to 3.27x10¹¹ Pa, and the conductive support plate has an area resistance value RS at 20° C. falling within a range from 0.032 (muOmega.cm²) to 1.24 (muOmega.cm²).
