Electrical energy store, specifically a battery cell, with spatially-optimized electrode interconnection

Abstract

An electrical energy store having a spatially-optimized electrode interconnection. The electrical energy store (1) comprises flat electrodes (3), flags (7) projecting laterally from the electrodes (3), and external terminals (9). A plurality of electrode regions are respectively stacked, one on top of another, to form an electrode stack (14). A plurality of flags (7) are arranged one on top of another in a flag stack (15), and are respectively materially bonded, both mutually and with an associated external terminal (9). The energy store is characterized in that each flag (7) of a plurality of flags (7) in a flag stack (15), which is bonded to the associated external terminal (9), is materially bonded to a respectively adjoining flag (7) in a region in which the flag (7) is oriented in an inclined direction at an angle (α) to the surface (11) of the associated external terminal (9).
