Abstract

The invention relates to an electrical energy storage module, comprising at least one storage cell stack (7) that has a plurality of groups of first planar parallel energy storage cells (1), each having first electrode elements (1a), and a plurality of groups of second planar parallel energy storage cells (2) arranged planar parallel to the group of first energy storage cells (1), said second groups each having second electrode elements (2a). The groups of first and second energy storage cells (1; 2) are arranged alternately along a first direction of extension of the storage cell stack (7) and the first electrode elements (1a) have a polarity on a side face of the storage cell stack (7) that is different from the second electrode elements (2a) on the side face of the storage cell stack (7). The energy storage module further comprises a plurality of flat contact elements (5) that are arranged on the side faces of the storage cell stack (7), galvanically connect adjacent groups of first and second energy storage cells (1; 2), and contact substantially all first or second electrode elements (1a; 2a) of the adjacent groups of first and second energy storage cells (1; 2) across the wid…
