ALL-SOLID-STATE BATTERY AND PRODUCTION METHOD THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240178457 titled 'ALL-SOLID-STATE BATTERY AND PRODUCTION METHOD THEREFOR
Simplified Explanation
The patent application describes an all-solid-state battery with a unique cell laminate structure and a resin layer for protection.
- The battery includes two or more unit cells within the cell laminate.
- Each unit cell consists of layers including positive and negative electrodes, solid electrolyte, and current collectors.
- Some layers have extending parts that create gaps between them on the side surface of the cell laminate.
- The compressive modulus ratio between the resin layer and the cell laminate is 0.4 or less.
Potential Applications
The technology could be applied in electric vehicles, portable electronics, and energy storage systems.
Problems Solved
This innovation addresses issues related to battery safety, energy density, and performance degradation.
Benefits
The all-solid-state battery offers improved stability, higher energy density, and longer lifespan compared to traditional batteries.
