SOLID-STATE BATTERY NEGATIVE ELECTRODE, SOLID-STATE BATTERY, AND METHOD FOR MANUFACTURING SOLID-STATE BATTERY NEGATIVE ELECTRODE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18227736 titled 'SOLID-STATE BATTERY NEGATIVE ELECTRODE, SOLID-STATE BATTERY, AND METHOD FOR MANUFACTURING SOLID-STATE BATTERY NEGATIVE ELECTRODE

Simplified Explanation

The abstract describes a solid-state battery negative electrode that includes a negative electrode active material layer with a solid electrolyte. The negative electrode active material has a high aspect ratio and a low elastic modulus. The solid-state battery includes a positive electrode, a negative electrode, and a solid electrolyte layer.

• The negative electrode of the solid-state battery includes a negative electrode active material layer.
• The negative electrode active material layer contains a negative electrode active material and a solid electrolyte.
• The negative electrode active material has an average aspect ratio greater than 0.5.
• The negative electrode active material has an average elastic modulus of 370 MPa or less.
• The solid-state battery includes a positive electrode and a negative electrode.
• A solid electrolyte layer is provided between the positive electrode and the negative electrode.
• The negative electrode described is the negative electrode of the solid-state battery.

Potential Applications

• This technology can be used in various electronic devices that require high-performance batteries, such as smartphones, laptops, and electric vehicles.
• It can also be applied in renewable energy storage systems, such as solar and wind power, to store energy efficiently.

Problems Solved

• The high aspect ratio of the negative electrode active material allows for better ion transport and improved battery performance.
• The low elastic modulus of the negative electrode active material reduces stress and strain during battery operation, leading to enhanced durability and longer battery life.
• The use of a solid electrolyte in the negative electrode active material layer eliminates the need for a liquid electrolyte, reducing the risk of leakage and improving safety.

Benefits

• The solid-state battery with the described negative electrode offers improved energy storage capacity and efficiency.
• It provides enhanced durability and longer battery life due to the low elastic modulus of the negative electrode active material.
• The use of a solid electrolyte improves the safety of the battery by eliminating the risk of electrolyte leakage.
