SULFIDE-IMPREGNATED COLUMNAR SILICON ANODE FOR ALL-SOLID-STATE BATTERY AND METHOD OF FORMING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17869580 titled 'SULFIDE-IMPREGNATED COLUMNAR SILICON ANODE FOR ALL-SOLID-STATE BATTERY AND METHOD OF FORMING THE SAME
Simplified Explanation
- The patent application describes an all-solid-state electrochemical cell. - The cell includes an electrode with a current collector and an electroactive material layer. - The electroactive material layer consists of hierarchical silicon columns and a solid sulfide electrolyte. - The solid sulfide electrolyte is formed in-situ and fills a significant portion of the voids in the electroactive material layer. - The voids are the openings between the hierarchical silicon columns. - The hierarchical silicon columns have a longest dimension perpendicular to the major axis of the current collector.
Original Abstract Submitted
An all-solid-state electrochemical cell is provided. The electrochemical cell includes an electrode having a current collector that defines a major axis, and an electroactive material layer disposed on or adjacent to the current collector. The electroactive material layer includes a plurality of hierarchical silicon columns, and a solid sulfide electrolyte. The solid sulfide electrolyte is formed in-situ and fills greater than or equal to about 60 vol. % to less than or equal to about 100 vol. % of voids in the electroactive material layer. The voids being defined by openings between the hierarchical silicon columns. A longest dimension of each hierarchical silicon columns is perpendicular to the major axis of the second current collector.
