SOLID-STATE BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18588425 titled 'SOLID-STATE BATTERY

Simplified Explanation: The patent application describes a solid-state battery design with multiple layers including current collectors, active material layers, and a solid electrolyte layer.

  • The battery includes a first current collector layer with a tab, a first active material layer, a second current collector layer with a tab, a second active material layer, and a solid electrolyte layer.
  • The solid electrolyte layer covers the end surfaces of the first current collector layer and the first active material layer, except for where the first current collector tab is located.

Key Features and Innovation:

  • Unique design of a solid-state battery with specific layer arrangements.
  • Use of a polymer electrolyte in the solid electrolyte layer.
  • Efficient utilization of space within the battery design.

Potential Applications:

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

Problems Solved:

  • Enhanced battery performance.
  • Improved safety due to solid-state design.
  • Increased energy density.

Benefits:

  • Longer battery life.
  • Faster charging capabilities.
  • Safer operation.

Commercial Applications: Solid-State Battery Design for Electric Vehicles and Portable Electronics: Market Implications

Prior Art: Research on solid-state battery technology and advancements in battery design.

Frequently Updated Research: Ongoing studies on polymer electrolytes in solid-state batteries.

Questions about Solid-State Battery Design: 1. What are the key advantages of using a solid-state battery design? 2. How does the polymer electrolyte in the solid electrolyte layer contribute to the overall performance of the battery?


Original Abstract Submitted

A solid-state battery includes: a first current collector layer having a first current collector tab protruding from one side of a quadrilateral; a first active material layer laminated on the first current collector layer; a second current collector layer having a second current collector tab protruding from one side of a quadrilateral; a second active material layer laminated on the second current collector layer; and a solid electrolyte layer arranged between the first active material layer and the second active material layer and including a polymer electrolyte, wherein, in three sides other than the one side where the first current collector tab is arranged, the solid electrolyte layer is arranged so as to cover end surfaces of the first current collector layer and the first active material layer.
