Title:
POSITIVE ELECTRODE MATERIAL, ALL-SOLID-STATE BATTERY, AND METHOD FOR PRODUCING POSITIVE ELECTRODE MATERIAL AND ALL-SOLID-STATE BATTERY
Document Type and Number:
WIPO Patent Application WO/2014/073469
Kind Code:
A1
Abstract:
Provided are a positive electrode material that enhances battery characteristics, an all-solid-state battery, and a method for producing the positive electrode material and the all-solid-state battery. The positive electrode material contains a positive electrode active material, a solid sulfide electrolyte, and filamentous carbon. The filamentous carbon is unevenly distributed around the positive electrode active material. The all-solid-state battery (10) is provided with a positive electrode layer (11) comprising the abovementioned positive electrode material, a negative electrode layer (12), and a solid electrolyte layer (13) disposed between the positive electrode layer (11) and the negative electrode layer (12).
