Abstract
Official abstract text for this publication.
Provided is a sulfide all-solid battery having an anode current collector of powerful adhesiveness which is difficult to be sulfurized. The sulfide all-solid-state battery including: a cathode layer; an anode layer; and a sulfide solid electrolyte layer disposed between the cathode layer and the anode layer, wherein the anode layer has an anode mixture layer, and an anode current collector on a face of the anode mixture layer, the face being on an opposite side of the sulfide solid electrolyte layer, the anode current collector is electrolytic iron foil that does not substantially contain other elements, and the anode current collector has surface roughness Ra of 0.2 μm to 0.6 μm, and surface roughness Rz of 2 μm to 6 μm.
First claim
Opening claim text (preview).
What is claimed is: 1. A sulfide all-solid-state battery comprising: a cathode layer; an anode layer; and a sulfide solid electrolyte layer disposed between the cathode layer and the anode layer, wherein the anode layer has an anode mixture layer, and an anode current collector on a face of the anode mixture layer, the face being on an opposite side of the sulfide solid electrolyte layer, the anode current collector is an electrolytic iron foil that does not substantially contain other elements, the anode current collector has surface roughness Ra of 0.2 μm to 0.6 μm, and surface roughness Rz of 2 μm to 6 μm, and the anode current collector has surface Martens hardness of 1090 N/mm 2 to 2820 N/mm 2 . 2. The sulfide all-solid-state battery according to claim 1 , wherein an elongation percentage of the anode current collector is 5% to 12%. 3. The sulfide all-solid-state battery according to claim 1 , wherein the anode current collector has surface Martens hardness of 1090 N/mm 2 _to 2050 N/mm .
