ALL-SOLID SECONDARY BATTERY, AND METHOD OF MANUFACTURING ALL-SOLID SECONDARY BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18446805 titled 'ALL-SOLID SECONDARY BATTERY, AND METHOD OF MANUFACTURING ALL-SOLID SECONDARY BATTERY

Simplified Explanation

The abstract describes an all-solid secondary battery that includes a cathode layer, an anode layer, and a solid electrolyte layer. The solid electrolyte layer is positioned between the cathode layer and the anode layer. The anode layer consists of an anode current collector, a first anode active material layer in contact with the solid electrolyte layer, and a second anode active material layer located between the anode current collector and the first anode active material layer. The first anode active material layer contains a first carbonaceous anode active material, and the second anode active material layer is not specified.

  • The all-solid secondary battery includes a cathode layer, an anode layer, and a solid electrolyte layer.
  • The solid electrolyte layer is positioned between the cathode layer and the anode layer.
  • The anode layer comprises an anode current collector, a first anode active material layer, and a second anode active material layer.
  • The first anode active material layer is in contact with the solid electrolyte layer and contains a first carbonaceous anode active material.
  • The second anode active material layer is located between the anode current collector and the first anode active material layer.

Potential Applications:

  • Energy storage for portable electronic devices such as smartphones, tablets, and laptops.
  • Power supply for electric vehicles and hybrid electric vehicles.
  • Backup power systems for telecommunications and data centers.
  • Integration into renewable energy systems for storing excess energy.

Problems Solved:

  • Improved safety compared to traditional liquid electrolyte batteries due to the use of a solid electrolyte.
  • Enhanced energy density and stability of the battery.
  • Potential for longer cycle life and improved performance.

Benefits:

  • Increased safety due to the elimination of flammable liquid electrolytes.
  • Higher energy density allows for longer battery life and increased capacity.
  • Improved stability and performance, leading to more reliable and efficient energy storage.
  • Potential for longer cycle life, reducing the need for frequent battery replacements.
