Title:
ELECTRODE FOR ALL-SOLID-STATE BATTERY AND ALL-SOLID-STATE BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/189818
Kind Code:
A1
Abstract:
The present invention provides an all-solid-state battery having a large capacity and excellent output properties, and an electrode capable of constituting said all-solid-state battery. The all-solid-state battery of the present invention relates to Goals 3, 7, 11, and 12 of the SDGs. An electrode for an all-solid-state battery according to the present invention comprises a compact of an electrode mixture containing at least an electrode active material, a solid-state electrolyte, and a conduction-assisting agent, and is characterized in that the particles of the conduction-assisting agent have an aspect ratio A, obtained by observation of the cross-section of the compact of the electrode mixture, of 1.5 or more, a distance L between the particles of the conduction-assisting agent in a three-dimensional space, and a length b of the major axis of the particles of the conduction-assisting agent, the distance L and the length b being obtained by observation of said cross-section, and said distance L and said length b satisfying the relationship L ≤ b. The all-solid-state battery according to the present invention is characterized in that the positive electrode and/or the negative electrode is constituted by the electrode for the all-solid-state battery according to the present invention.
