Title:
ELECTROCHEMICAL REACTION VISUALIZATION DEVICE AND ELECTROCHEMICAL REACTION VISUALIZATION METHOD
Document Type and Number:
Japanese Patent JP2023132119
Kind Code:
A
Abstract:
To provide: an electrochemical reaction visualization device capable of easily discriminating between an active material and an electrolyte; and an electrochemical reaction visualization method.SOLUTION: An electrochemical reaction visualization device 100 according to the present disclosure, comprises: a cell 10 with a window, housing a secondary battery 1; a charge and discharge controller 20 that controls charging and discharging; a color confocal imaging part 30 that includes an objective lens 34 for transmitting a reflectance derived from an illumination light through reflection on the secondary battery 1; and an imaging processing part that acquires color image data and charging and discharging data in a charging state of the secondary battery 1. The image processing part includes: a master extraction part that selects the color image data in a full-charging state, extracts an active material part in the selected color image data, and extracts a range surrounding the active material part as a tracking ROI; and a slave extraction part that tracks a position of the extracted active material part in the color image data corresponded to each charging state, and extracts the range surrounding the tracked active material part as a tracking ROI.SELECTED DRAWING: Figure 1
