[0071] For the basis Figure 12 In the seventh embodiment of the view, a connection as in the preceding embodiments is also possible, of course avoiding the enclosing of the film stack 8 by one of the power supply leads 10 , 12 . For this embodiment, the two power supply leads 10 , 12 with an L-shaped cross-section are arranged on the same narrow side of the film stack 8 , wherein parts of the sides of the L-profile of the power supply leads 10 , 12 facing the film stack 8 are separated by The grooves are formed in a mutually engaging manner. Note that the anode power lead 10 is broken in the figure only for clarity of the cross section. In fact, the anode power lead 10 is an uninterrupted block of profile.

[0072] Figure 13 The eighth embodiment is shown in . This view corresponds to image 3 The view in , but only shows the upper half of frame part 4. In this embodiment, instead of the centering joint 22 , a centering sleeve 42 is provided which is placed in the bore...

Abstract

An electrical energy storage cell is provided with: an active part which is equipped and adapted to store electrical energy supplied from the outside and to discharge stored electrical energy to the outside; at least two current conductors which are connected to the active part and are equipped and adapted to supply electric current from the outside to the active part and to discharge electric current from the active part to the outside; and an enclosure, which defines a prismatic basic shape having a substantially cuboid-like outline and encloses the active part in a gas-tight and fluid-tight manner.; According to the invention, the enclosure has two flat foil parts and a peripheral seam part connecting the edges of the foil parts, wherein the seam part surrounds the active part in the manner of the frame and has sections of maximum thickness, in which the thickness is uniformly greater than the thickness of the active part. A cell block comprises a plurality of said electrical energy storage cells, wherein the cells are stacked in the direction of the thickness thereof and, together with connecting terminals, form an electrical energy storage device which can advantageously be used in a vehicle.

Description

technical field [0001] The invention relates to an electric energy storage unit, a battery block composed of a plurality of interconnected electric energy storage units, an electric energy storage device with a battery block, and a vehicle with the electric energy storage device. Background technique [0002] Batteries (primary accumulators) and accumulators (secondary accumulators) for storing electrical energy are known consisting of one or more storage units in which, by applying a charging current, between the anode and the cathode or In an electrochemical charging reaction in the electrolyte, electrical energy is converted into chemical energy and thus stored, and when an electrical load is switched on, chemical energy is converted into electrical energy in an electrochemical discharge reaction. Here, primary energy stores are usually only charged once and discarded after discharge, whereas secondary energy stores allow many cycles of charge and discharge (from a few hu...
