ALL SOLID STATE BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240250294 titled 'ALL SOLID STATE BATTERY

The present disclosure describes an all solid-state battery with excellent cycle characteristics.

• The battery includes a cathode, a first solid electrolyte layer, an anode, a second solid electrolyte layer, and another cathode arranged in a specific order along the thickness direction.
• The first solid electrolyte layer contains a first nonwoven fabric with a solid electrolyte inside it, while the second solid electrolyte layer contains a second nonwoven fabric with a solid electrolyte inside it.
• In a plan view along the thickness direction, the angle between the fabric directions of the two nonwoven fabrics is between 45° and 90°.

Potential Applications: - Energy storage systems - Electric vehicles - Portable electronic devices

Problems Solved: - Improved cycle characteristics in solid-state batteries - Enhanced battery performance and reliability

Benefits: - Longer battery life - Higher energy density - Safer and more stable battery operation

Commercial Applications: Solid-state batteries can be used in various industries such as automotive, electronics, and renewable energy storage systems. The technology can revolutionize the way we power our devices and vehicles.

Questions about Solid-State Batteries: 1. How do solid-state batteries differ from traditional lithium-ion batteries? Solid-state batteries use solid electrolytes instead of liquid electrolytes, making them safer and potentially more efficient.

2. What are the main challenges in scaling up the production of solid-state batteries for commercial use? Scaling up production while maintaining quality control and cost-effectiveness is a significant challenge in the commercialization of solid-state batteries.

Original Abstract Submitted

a main object of the present disclosure is to provide an all solid state battery with excellent cycle characteristics. the present disclosure achieves the object by providing an all solid state battery comprising, in an order of, a cathode ca, a first solid electrolyte layer, an anode an, a second solid electrolyte layer, and a cathode ca, along a thickness direction, wherein: the first solid electrolyte layer contains a first nonwoven fabric, and a first solid electrolyte arranged inside the first nonwoven fabric; the second solid electrolyte layer contains a second nonwoven fabric, and a second solid electrolyte arranged inside the second nonwoven fabric; and in a plan view along the thickness direction, an angle formed by a first fabric direction in the first nonwoven fabric and a second fabric direction in the second nonwoven fabric is 45� or more and 90� or less.
