Abstract
An analysis device of an embodiment is an analysis device of an active material layer of an electrode of a secondary battery, and includes a processor configured to execute a program to acquire image data that represents active materials in the active material layer processed by ion milling and voids or fillings between the active materials by a difference in brightness, and compare patterns of the difference in brightness between the image data in at least two different states of the active material layer.
Claims12
An analysis device of an active material layer of an electrode of a secondary battery, the analysis device comprising a processor configured to execute a program to:
- acquire image data that represents active materials in the active material layer processed by ion milling and voids or fillings between the active materials by a difference in brightness;
- and
- compare patterns of the difference in brightness between the image data in at least two different states of the active material layer.
An analysis method of an active material layer of an electrode of a secondary battery, the analysis method comprising;
- by a computer,
- acquiring first image data that represents active materials in the active material layer and voids or fillings between the active materials by a difference in brightness in a first state of the active material layer processed by ion milling;
- acquiring second image data that represents the active materials in the active material layer and voids or fillings between the active materials by a difference in brightness in a second state different from the first state of the processed active material layer;
- and
- comparing patterns of the difference in brightness between the first image data and the second image data.
A non-transitory computer-readable storage medium storing a program that analyzes an active material layer of an electrode of a secondary battery, and causes a computer to execute:
- acquiring first image data that represents active materials in the active material layer and voids or fillings between the active materials by a difference in brightness in a first state of the active material layer processed by ion milling;
- acquiring second image data that represents the active materials in the active material layer and voids or fillings between the active materials by a difference in brightness in a second state different from the first state of the processed active material layer;
- and
- comparing patterns of the difference in brightness between the first image data and the second image data.
