Title:
高温寸法安全性及び集合組職安全性を有する電解銅箔及びその製造方法
Document Type and Number:
Japanese Patent JP7083029
Kind Code:
B2
Abstract:
The present invention relates to: an electrolytic copper foil having high dimensional stability and texture stability in a high temperature environment of a process for manufacturing an Li secondary battery; and a manufacturing method therefor. The electrolytic copper foil of the present invention has a thermal expansion coefficient of 17.1-22 µm/(m·°C) in a temperature regionof 30-190°C, has a variation of full width at half maximum of the (220) plane of 0.81-1.19 according to heat treatment for 30 minutes at 190°C, and has a weight deviation of 5% or less in the transverse direction.
