ALL SOLID STATE BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240250308 titled 'ALL SOLID STATE BATTERY

The abstract describes an all-solid-state battery with an electrode structure body containing a cathode layer, an anode layer, and a solid electrolyte layer between them. The facing part of the electrode structure body has a rectangular shape with a longer side and a shorter side, where the ratio of the longer side to the shorter side is 1.5 or more. The solid electrolyte layer includes a nonwoven fabric with the solid electrolyte arranged inside it. The angle between the longer direction in the facing part and the fabric direction in the nonwoven fabric is between 0° and 30°.

  • The all-solid-state battery features an electrode structure body with specific dimensions and a solid electrolyte layer containing a nonwoven fabric.
  • The facing part of the electrode structure body has a rectangular shape with a specific ratio of longer side to shorter side.
  • The solid electrolyte layer includes a nonwoven fabric with the solid electrolyte arranged inside it.
  • The angle between the longer direction in the facing part and the fabric direction in the nonwoven fabric is limited to a specific range.

Questions about All-Solid-State Battery Technology: 1. How does the use of a nonwoven fabric in the solid electrolyte layer improve battery performance? The nonwoven fabric provides structural support and helps distribute the solid electrolyte evenly, enhancing the overall performance of the battery.

2. What advantages does the rectangular shape of the facing part of the electrode structure body offer in terms of battery design and performance? The rectangular shape allows for a more efficient and compact battery design, optimizing the space utilization and improving the overall performance of the battery.


Original Abstract Submitted

an all solid state battery includes an electrode structure body including a cathode layer, an anode layer, and a solid electrolyte layer arranged between the cathode layer and the anode layer, wherein: the electrode structure body includes a facing part where the cathode layer and the anode layer face to each other; in a plan view along a thickness direction, a shape of the facing part is a rectangular shape including a longer side and a shorter side; a rate of a length of the longer side with respect to a length of the shorter side is 1.5 or more; the solid electrolyte layer contains a nonwoven fabric, and a solid electrolyte arranged inside the nonwoven fabric; and in the plan view, an angle formed by a longer direction in the facing part and a fabric direction in the nonwoven fabric is 0� or more and 30� or less.
