ALL-SOLID-STATE BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240194939 titled 'ALL-SOLID-STATE BATTERY

Simplified Explanation: The patent application describes an all-solid-state battery with a unique structure and a resin layer covering its side surface.

  • The all-solid-state battery laminate includes layers for positive and negative electrodes, solid electrolyte, and current collectors, all laminated together.
  • The positive and negative electrode current collector layers have parts that overlap and extend beyond adjacent layers.
  • The extending parts have greater surface roughness compared to the overlapping parts.

Key Features and Innovation:

  • Unique structure of an all-solid-state battery with specific layer arrangements.
  • Resin layer covering the side surface of the battery laminate.
  • Surface roughness variation in the current collector layers for improved performance.

Potential Applications:

  • Energy storage for electric vehicles.
  • Portable electronic devices.
  • Grid energy storage systems.

Problems Solved:

  • Enhanced battery performance.
  • Improved structural integrity.
  • Better efficiency in energy storage.

Benefits:

  • Higher energy density.
  • Longer battery life.
  • Enhanced safety due to solid-state design.

Commercial Applications:

  • Electric vehicle batteries.
  • Consumer electronics.
  • Renewable energy storage solutions.

Prior Art: Prior research on solid-state batteries and current collector designs can provide insights into similar innovations.

Frequently Updated Research: Ongoing studies on solid-state battery materials and manufacturing processes can impact the development of this technology.

Questions about All-Solid-State Batteries: 1. What are the key advantages of using solid-state batteries over traditional lithium-ion batteries? 2. How does the surface roughness of current collector layers affect the performance of the battery?


Original Abstract Submitted

an all-solid-state battery, including an all-solid-state battery laminate including at least one all-solid-state unit cell in which a positive electrode current collector layer, a positive electrode active material layer, a solid electrolyte layer, a negative electrode active material layer, and a negative electrode current collector layer are laminated in this order, and a resin layer covering a side surface of the all-solid-state battery laminate. at least one surface of at least one of the positive electrode current collector layer and the negative electrode current collector layer includes a laminated part and an extending part. the laminated part is a portion which overlaps another adjacent layer, and the extending part is a portion which extends beyond the other adjacent layer. the surface roughness of the extending part is greater than the surface roughness of the laminated part.
