Abstract
The utility model aims to provide non-woven fabric tab glue which is characterized in that the intermediate layer of the tab glue is a non-woven fabric layer, and modified CPP (cast polypropylene) layers or resin layers are coated on two surfaces of the non-woven fabric layer in a squeezed manner. The non-woven fabric of the intermediate layer can be high-density non-woven fabric with different colors including yellow, red, green, black or other colors. The thickness of the non-woven fabric is not more than 0.08 mm. The thickness of each modified CPP layer is not more than 0.06 mm. The aggregate thickness of the modified CPP layers or the resin layers is not more than 0.20 mm. The product of the non-woven fabric tab glue provided by the utility model is flexible and bendable, can meet the requirements for encapsulating lithium ion batteries, particularly, when the positive and negative poles of a battery is distinguished, and the tab glue with different colors can be selected, so as to distinguish the positive and negative poles conveniently.
