Embodiment Construction

[0033] exist Figure 1 to Figure 3 In , a lithium-ion battery cell 100 is shown as a first preferred embodiment of an electrical energy storage cell according to the invention. in, figure 1 is a general perspective view of the battery unit 100, figure 2 for along figure 1 The longitudinal section view of the plane II formed by the dotted line shown in the direction indicated by the arrow, image 3 for passing in figure 2 An enlarged view of detail III is given by the dotted line shown.

[0034] Such as figure 1 As shown, the battery cell 100 essentially has a prismatic base body 2 and two sheet-shaped power supply leads 4 , 6 .

[0035] Matrix 2 accommodates the figure 1 The active part of the memory cell 100 shown in , and the length of the substrate 2 is L, the width is W, and the thickness is T. It can be determined that the thickness T is significantly smaller than the width W and the length L. In the particular embodiment shown, the width W is less than the len...

Abstract

The electrical energy storage unit according to the invention has: an active part arranged and adapted to store electrical energy supplied from the outside and to release the stored electrical energy to the outside; enclosing the active part; and at least two power supply leads connected to the active part and arranged and adapted to supply current to the active part from the outside and discharge current from the active part to the outside, wherein the part surrounded by the casing is The form of a substantially parallelepiped is a prismatic structure which is less extended in a first spatial direction than in the other two spatial directions and substantially defines two opposing parallel planes and a connecting plane Four narrow faces, and wherein the faces of the first and second power leads parallel to the two planes protrude from the housing in opposite directions from the two narrow faces facing each other. The protruding extent of the first and second power leads along the narrow face is greater than half of the length of the narrow face.

Description

technical field [0001] The invention relates to an electrochemical energy storage unit according to the preamble of claim 1 . Background technique [0002] Batteries (primary accumulators) and accumulators (secondary accumulators) are known for storing electrical energy, which consist of one or more storage cells which, when a charging current is applied, pass through a cathode and an anode in or between an electrolyte The electrochemical charging reaction between the electrical energy is converted into chemical energy and stored, and when the electrical load is turned on, the chemical energy is converted into electrical energy through the electrochemical discharge reaction. Here, primary accumulators can essentially only be charged once and then discarded after being discharged, secondary accumulators allow multiple (hundreds to over 10,000) repetitions of charging and discharging. Note also that accumulators, sometimes also referred to as batteries, such as vehicle batter...
