Abstract

The embodiment of the invention provides a representation method for cohesion of a coating. The method includes the steps that adhesive tape is pasted to the face, provided with the coating, of a to-be-tested piece with one face provided with the coating, and one end of the adhesive tape is reserved and is not pasted to the to-be-tested piece; the to-be-tested piece is fixed, the adhesive tape is stripped from the surface of the coating through the end, not pasted to the to-be-tested piece, of the adhesive tape, stripping force generated after the adhesive tape is stripped from the surface of the coating is tested, and the cohesion value of the coating is represented through the stripping force. According to the method, the cohesion of the coating can be accurately and quantitatively represented.

Description

technical field

[0001] The invention relates to the technical field of material analysis and testing, in particular to a method for characterizing coating cohesion. Background technique

[0002] In recent years, with the emphasis on non-renewable energy crisis and environmental protection, battery electric vehicles have become a development trend. Green and environmentally friendly lithium-ion batteries are an important part of electric vehicles, and the development and production of batteries is an important factor restricting the development of the entire electric vehicle industry. The microstructure of the lithium-ion battery pole piece coating is composed of molecular-level sublayers, and the cohesion of the coating is the adhesion between these sublayers. The coating cohesion of the battery pole piece can not only reflect the difference in adhesion between the coating sublayers of the lithium-ion battery pole piece, but also directly affect the internal resistance and ...
