POSITIVE-ELECTRODE MIXTURE AND ALL-SOLID-STATE SODIUM-SULFUR BATTERY |
摘要 |
The present invention aims to maximize the advantageous physical properties of sulfur and provide a cathode mixture that can be suitably used in a cathode mixture layer of an all-solid-state sodium-sulfur battery in which charge/discharge capacity can be ensured even during operation at normal temperature. The present invention also aims to provide an all-solid-state sodium-sulfur battery including a cathode mixture layer containing the cathode mixture. The present invention relates to a cathode mixture for use in a cathode mixture layer of an all-solid-state sodium-sulfur battery, the cathode mixture including the following components (A) to (C): (A) an ion-conductive material containing phosphorus at a weight ratio of 0.2 to 0.55; (B) sulfur and/or its discharge product; and (C) a conductive material, the component (C) containing a conductive material (C1) having a specific surface area of 1000 m 2 /g or more. |
