Title:
ELECTRODE MIXTURE, BATTERY, AND ELECTRODE MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2019133923
Kind Code:
A
Abstract:
To improve battery charge/discharge efficiency.SOLUTION: An electrode mixture according to the present disclosure includes a sulfide solid electrolyte (32) and a carbon-containing material (18) in contact with the sulfide solid electrolyte (32). In a spectrum obtained when the electrode mixture is analyzed by Auger electron spectroscopy, when the peak intensity of carbon contained in the carbon-containing material (18) is defined as C, and the peak intensity of sulfur contained in the sulfide solid electrolyte (32) is defined as S, the intensity ratio C/S satisfies a relationship of 0.2≤C/S≤1.SELECTED DRAWING: Figure 1
