Application: Assb cathode having controlled electronic conductive paths (Patent ID: US20240194883A1)
The patent filed by Nissan Motor Co Ltd describes a cathode composite layer for an all-solid-state battery (ASSB) cell, which includes cathode active material, a solid electrolyte, and conductive pathways. These pathways consist of cylindrical carbon nanostructures covered by an insulating sheath, with specific uncovered portions at the ends and adjacent to them. The uncovered portions are crucial for facilitating conductivity within the cell.
The claims associated with the patent detail the specific components and configurations of the ASSB cell, emphasizing the use of a sulfide-based electrolyte, the alignment of the conductive pathways parallel to the stacking direction of the cell, and the varying thickness of the insulating sheath along the cylindrical carbon nanostructure. The patent also mentions the materials that can be used for the insulating sheath, such as Al2O3, MgO, and polytetrafluoroethylene (PTFE). Overall, the patent focuses on optimizing the design of the cathode composite layer to enhance the performance and efficiency of ASSB cells.
