Coating is to apply a thin layer of coating material in liquid or powder form to the surface of an object such as a fabric, paper, foil or board.
A coating measurement system is a collection of instruments or test equipment, standards, operations, methods, fixtures, software, personnel, environments, and assumptions used to quantitatively measure or qualitatively evaluate a property being measured. The gist of the analysis (Measurement Systems Analysis, MSA) of the measuring system is that by means of statistical analysis, statistical variations and studies of the individual influencing factors constituting the measuring system are carried out in order to reach a conclusion as to whether the measuring system is accurate and reliable. For example, the detection device can be evaluated according to coating data such as coating weight, surface density and the like, and whether the coating measurement system is accurate and reliable can be judged from the angle of the detection device.
The coating is an indispensable step in the manufacturing process of the battery cell, and in the production process of the battery cell, the positive electrode plate and the negative electrode plate are both manufactured by using a coating process. Illustratively, the positive electrode active material, the conductive agent, the binder, and the solvent are mixed and made into a paste-like viscous slurry, and then the paste-like viscous slurry is uniformly, continuously, or intermittently coated on a substrate (e.g., aluminum foil) to make a positive electrode sheet.

Repeatability can be calculated from multiple coating detection data for the same coating. Reproducibility can be calculated from coating detection data for different coatings. In some examples, the MSA evaluation criterion is a criterion for evaluating the stability of the detection device according to a specific detection rule based on the detected data, and may be implemented by the computing device executing a set evaluation program, which is not described herein.
