ELECTRODE MATERIAL, ELECTRODE, AND ALL-SOLID-STATE BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18345176 titled 'ELECTRODE MATERIAL, ELECTRODE, AND ALL-SOLID-STATE BATTERY

Simplified Explanation

The patent application describes an electrode material that consists of a composite particle. This composite particle includes a core particle and a covering layer that partially covers the surface of the core particle. The core particle contains an active material, while the covering layer is composed of a first layer and a second layer. The first layer, which is situated between the core particle and the second layer, contains a solid electrolyte made of fluoride. The second layer contains a solid electrolyte made of sulfide.

  • The electrode material is a composite particle consisting of a core particle and a covering layer.
  • The core particle contains an active material.
  • The covering layer includes a first layer and a second layer.
  • The first layer, made of a fluoride solid electrolyte, is located between the core particle and the second layer.
  • The second layer is composed of a sulfide solid electrolyte.

Potential Applications:

  • This electrode material can be used in various electrochemical devices, such as batteries and fuel cells.
  • It can improve the performance and efficiency of these devices by providing a stable and conductive interface between the active material and the electrolyte.

Problems Solved:

  • The electrode material addresses the issue of poor interface stability between the active material and the electrolyte in electrochemical devices.
  • It solves the problem of limited conductivity and ion transfer at the electrode-electrolyte interface.

Benefits:

  • The composite particle structure enhances the stability and conductivity of the electrode material.
  • The use of different solid electrolytes in the covering layer improves the overall performance and efficiency of electrochemical devices.
  • The electrode material can potentially enable the development of more efficient and durable batteries and fuel cells.


Original Abstract Submitted

An electrode material comprises a composite particle. The composite particle includes a core particle and a covering layer. The covering layer covers at least part of a surface of the core particle. The core particle includes an active material. The covering layer includes a first layer and a second layer. At least part of the first layer is interposed between the core particle and the second layer. The first layer includes a first solid electrolyte. The second layer includes a second solid electrolyte. The first solid electrolyte is a fluoride. The second solid electrolyte is a sulfide.
