Embodiment Construction

[0026] Directional terms used below - i.e. terms such as "left", "right", "upper", "lower", "front", "rear", "above", "behind", etc. Terminology - is used only for better understanding of the drawings and should in no way represent a general limitation. In general, identical reference numbers designate identical or identically acting components.

[0027] An electrical energy store electrolytic cell within the meaning of the present invention includes all devices which can store electrical energy over a predefined time span and deliver it again over another time span. An energy store electrolytic cell in the sense of the invention includes all types of primary and secondary energy stores, in particular capacitive, electrochemical (Faraday) and combined energy store types. In this case, the period of time considered may comprise from a few seconds to hours, days or years. Electrolytic cells for electrical energy storage may include, for example: lithium ion electrolytic cells,...

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 width of the storage cell stack (7) in each case.

Description

technical field [0001] The invention relates to an electrical energy storage module and a method for producing an electrical energy storage module. Background technique [0002] Typically, a direct current is drawn from or fed into the electrolytic cell of the electric energy storage. The hitherto known designs of energy store electrolytic cells are therefore designed for optimization of the ohmic internal resistance and the specific energy density or specific power density of the energy store electrolytic cell. [0003] In many applications of electrical energy storage electrolytic cells, the energy storage electrolytic cells are interconnected to each other in a series or parallel arrangement to form battery modules in order to adjust desired output parameters such as overall voltage, voltage range, energy content or power density. If a current with an increased AC component is drawn from such an energy storage cell, the frequency-dependent influence of the distributed in...
