Title:
DOUBLE-SIDED ADHESIVE TAPE AND LITHIUM ION BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/046090
Kind Code:
A1
Abstract:
The present application provides a double-sided adhesive tape and a lithium ion battery. The first aspect of the present application provides a double-sided adhesive tape, the double-sided adhesive tape comprising a first bonding layer, a base material layer and a second bonding layer which are sequentially stacked. The first bonding layer comprises one or more among organic silicon binders, epoxy binders, polyurethane binders, polyacrylic acid binders and rubber binders, and the bonding strength of the first bonding layer is greater than that of the second bonding layer. The double-sided adhesive tape provided in the present application comprises the two bonding layers, and the bonding strength of the first bonding layer is greater than that of the second bonding layer, and the double-sided adhesive tape may be effectively and accurately bonded on a surface of a light soft material by using a means of transferring an object to assist in gluing, thereby effectively solving the problems of wrinkling, poor positioning, bubbles appearing and the like in gluing.
