Title:
電池集電体用クラッド材および電極
Document Type and Number:
Japanese Patent JP6528814
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a clad material for a battery current collector, which can suppress the occurrence of a large warp while suppressing the increase in the contact resistance with an active material.SOLUTION: A clad material 1 for a current collector (i.e. a clad material for a battery current collector) is composed of a clad material having a double layer structure in which an Al layer 11 disposed on a surface 1a and formed from an Al-based alloy, and a Cu layer 12 disposed on a surface 1b, and formed from a Cu-based alloy are joined to each other by rolling. The rate of a thickness t2 of the Al layer 11 to a total thickness (t1) of the Al layer 11 and the Cu layer 12 is 35% or less.SELECTED DRAWING: Figure 1
