Document Type and Number:
WIPO Patent Application WO/2024/018982
Kind Code:
A1
Abstract:
Provided is an all-solid-state battery having high electrical connection reliability in a current collecting structure. The all-solid-state battery according to the present invention relates to Goals 3, 7, 11, and 12 of the SDGs. The all-solid-state battery according to the present invention comprises an electrode stack which has a positive electrode, a negative electrode, and a solid electrolyte layer interposed between the positive electrode and the negative electrode, and which is housed in a battery container having a recessed container and a sealing body, wherein: the positive electrode and the negative electrode have a mixture layer and a sheet-like porous metal base material disposed on the surface of the mixture layer; at least part of the porous metal base material including a mixture layer-side end portion is embedded in the surface layer portion of the mixture layer, and is integrated with the mixture layer; the other end portion of the porous metal substrate is exposed to the surfaces of the positive electrode and the negative electrode; an elastic conductive member is arranged between the electrode stack and the inner bottom surface of the sealing body; and the elastic conductive member is electrically connected to a conductive path of the recessed container, and presses the electrode stack toward the inner bottom surface of the recessed container.
