Abstract
Description
technical field
[0001] The present application relates to the field of batteries, in particular, to an adhesive tape and a lithium-ion battery. Background technique
[0002] The adhesive paper in the cell assembly of the lithium-ion battery is mainly used to fix the current collector, cover the coating and protect the welding printing. The common adhesive paper is blue glue and green glue. Its structure includes a layer of base material and a layer of adhesive layer, the toner is dispersed in the adhesive layer, which usually leads to a decrease in the adhesive strength of the adhesive tape and cannot meet the needs of use. The base material provides protection performance, and the puncture strength of the adhesive paper is improved by increasing the thickness of the base material. However, due to the requirement of battery energy density, the thickness of the adhesive paper is limited, and the puncture strength of the adhesive paper cannot meet the demand. Therefore, under...
