ABSTRACT:
An electrochemical storage device having a metallic, gas-tight storage device housing in which an electrode stack formed from a plurality of electrode plates stacked on one another is accommodated. Arranged between the storage device housing and the electrode stack is a box-like stack insulation which is made from an electrically insulating material and which surrounds the electrode stack on the sides which come to bear directly against the housing interior. For the purpose of reliable flow of the quantity of gas occurring during operation, there are arranged on those circumferential sides of the stack insulation towards which the narrow sides of the electrode plates point material protuberances which cross over the narrow sides of the electrode plates and which are spaced apart from one another in order to form gas conduits.
