  • All-solid-state battery
    Patent number: 11431031
    Abstract: An all-solid-state battery configured to suppress capacity degradation. The all-solid-state battery may comprise a stack of a cathode layer, a solid electrolyte layer and an alloy-based anode layer, and a confining structure confining the stack in an approximately parallel direction to a stacking direction, wherein the cathode layer has a cathode plane on a side facing the solid electrolyte layer; wherein the alloy-based anode layer has an anode plane on a side facing the solid electrolyte layer; wherein the cathode plane and anode plane of the stack have a long axis direction and a short axis direction; and wherein at least one of the cathode plane and the anode plane has one or more slit channels.
    Type: Grant
