METHOD OF MANUFACTURING COMPOSITE ELECTRODE FOR ALL-SOLID-STATE BATTERY, AND COMPOSITE ELECTRODE FOR ALL-SOLID-STATE BATTERY MANUFACTURED THEREBY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240097119 titled 'METHOD OF MANUFACTURING COMPOSITE ELECTRODE FOR ALL-SOLID-STATE BATTERY, AND COMPOSITE ELECTRODE FOR ALL-SOLID-STATE BATTERY MANUFACTURED THEREBY

Simplified Explanation

The abstract describes a method of manufacturing a composite electrode for an all-solid-state battery. Here are the key points:

• Preparation of a precursor solution by mixing solid electrolyte precursor and polar solvent.
• Stirring the precursor solution.
• Creating an electrode slurry by adding an active material to the stirred precursor solution.
• Heat-treating the electrode slurry to obtain the composite electrode for the all-solid-state battery, which includes the active material and a coating layer with a solid electrolyte.

Potential Applications

The technology can be applied in the manufacturing of all-solid-state batteries, which are known for their safety and high energy density.

Problems Solved

This method addresses the challenge of producing composite electrodes with solid electrolyte coatings for all-solid-state batteries, which are crucial for enhancing battery performance and stability.

Benefits

The composite electrode produced through this method offers improved battery performance, safety, and longevity, making it suitable for various energy storage applications.

Potential Commercial Applications

The technology can be utilized in the production of advanced batteries for electric vehicles, portable electronics, and grid energy storage systems.

Possible Prior Art

One possible prior art could be the use of traditional electrode manufacturing methods without solid electrolyte coatings, which may result in lower battery performance and safety compared to the composite electrodes produced by this method.

Unanswered Questions

What is the specific composition of the solid electrolyte precursor used in the method?

The abstract does not provide details on the exact materials used as the solid electrolyte precursor, which could impact the performance of the composite electrode.

How does the heat treatment process affect the properties of the composite electrode?

The abstract mentions heat-treating the electrode slurry but does not elaborate on the specific temperature or duration of the heat treatment, which could influence the final characteristics of the electrode.
