Abstract
The present disclosure relates to a method for predicting the occurrence of electrode crack and delamination, and the objective of the present disclosure is to provide a method for predicting the occurrence of electrode crack and delamination, the method comprising: measuring crack force for a dried electrode; and predicting the occurrence of crack and delamination of the electrode on the basis of the measured crack force.
Claims13
A method for predicting occurrence of cracks and delamination of an electrode, comprising:
- a step of preparing an electrode to be analyzed by applying an electrode slurry to one surface of an electrode current collector and then drying it;
- a step of press-fitting a measuring point into a surface of the electrode to be analyzed;
- a step of collecting data by collecting indentation load values applied to the measuring point for each indentation depth value of the measuring point for the electrode to be analyzed;
- a step of extracting a crack force by extracting an indentation load value at the time that the electrode to be analyzed is broken as a crack force value;
- and
- a prediction step of predicting occurrence of cracks and delamination of the electrode to be analyzed using the crack force value.
