All-Solid-State Battery - A simplified explanation of the abstract

This abstract first appeared for US patent application 18347657 titled 'All-Solid-State Battery

Simplified Explanation

The abstract describes an all-solid-state battery with a positive electrode layer, a separator layer, and a negative electrode layer. The separator layer contains a sulfide solid electrolyte. The patent application proposes a method to measure the atom concentration of sulfur and iodine in the separator layer using SEM-EDX analysis. A regression line is derived from the results, with a slope between 0.019 and 0.036. The position in the thickness direction of the separator layer is the independent variable, and the ratio of iodine to sulfur atom concentration is the dependent variable.

  • The patent application is for an all-solid-state battery with improved measurement and analysis techniques.
  • The battery consists of a positive electrode layer, a separator layer, and a negative electrode layer.
  • The separator layer contains a sulfide solid electrolyte.
  • The method proposed involves performing a line analysis using SEM-EDX to measure the atom concentration of sulfur and iodine.
  • The analysis is done on a straight line extending from the negative electrode layer to the positive electrode layer in parallel to the thickness direction of the separator layer.
  • A regression line is derived from the analysis results, with a slope between 0.019 and 0.036.
  • The position in the thickness direction of the separator layer is the independent variable.
  • The ratio of iodine to sulfur atom concentration is the dependent variable.

Original Abstract Submitted

The all-solid-state battery includes a positive electrode layer, a separator layer, and a negative electrode layer. The separator layer includes a sulfide solid electrolyte. In a cross section parallel to the thickness direction of the separator layer, a line analysis is performed by SEM-EDX to measure an atom concentration of sulfur and an atom concentration of iodine on a straight line extending from the negative electrode layer to the positive electrode layer in parallel to the thickness direction. A regression line is derived from the results of the line analysis, and the regression line has a slope of 0.019 to 0.036. The independent variable of the regression line is a position in the thickness direction of the separator layer. The dependent variable of the regression line is a ratio of the atom concentration of iodine to the atom concentration of sulfur.
