Title:
BINDER RATIO MEASURING DEVICE, BINDER RATIO MEASURING METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2020123492
Kind Code:
A
Abstract:
To measure a binder ratio of an electrode layer of an electrode sheet at high speed and with high accuracy.SOLUTION: In an electrode sheet having a pair of first surface and second surface, a heating unit 110 heats a first surface of an electrode sheet in which an electrode layer including a binder is formed on at least one of the first surface and the second surface, and a temperature measuring unit 120 measures the temperature of the second surface, and a binder ratio estimation unit 150 estimates a binder ratio which is a composition ratio of the binder in the electrode layer on the basis of the thermal diffusivity calculated on the basis of a temperature change in the second surface before and after heating the first surface by a thermal diffusivity calculating unit 130.SELECTED DRAWING: Figure 3
