Electrochemical storage device having improved electrical conduction properties

An electrochemical storage device comprising:

• an anode compartment filled with an anode material and a cathode compartment filled with a cathode material when in operation,
• wherein the anode compartment is separated from the cathode compartment by an ion-conductive solid electrolyte, and
• wherein the anode compartment is delimited on one side at least in part by the solid electrolyte and on another side at least in part by a wall which surrounds the solid electrolyte at least in part, wherein the wall is comprised of a top part of the electrochemical storage device, a bottom part arranged opposite the top part, and/or a side part arranged between top part and bottom part, and wherein the wall has an electrically conductive wall portion with a surface profile facing away from the electrochemical storage device, which is associated as an anode to the anode compartment,
• wherein an at least partly flat, electrically conductive conductor portion is electrically connected with the surface profile of the wall portion via a surface and wherein an electrical conductivity per unit area of the conductor portion is greater than that of the wall per unit area of the wall portion, wherein the wall portion has a wall thickness which is less than the thickness of the at least partly flat conductor portion in the region of the surface.
