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.
