Abstract

The present invention relates to a memory cell (1), in particular formed for a Lithium-ion battery, comprising a housing (2), a lid (3) tightly sealing the shell (2), at least one electrochemical element (4) having a positive current collector (5) and a negative current collector (6) and arranged in the shell (3), a positive current connection point (7) arranged on the outer surface of the shell (2) or the cover (3) and connected with the positive current collector (5) or a negative current collector (6) arranged on the outer surface of the shell (2) or the cover (3) and connected with the negative current collector (5), wherein the lid (3) and the housing (2) are connected with each other through a thin plastic layer (11) and the plastic layer (11) is attached to the housing (2) and the cover (3).

Description

technical field [0001] The invention relates to an energy storage cell, in particular designed as a lithium-ion battery. The energy storage cells are preferably used in motor vehicles. Accumulator cells are used in vehicles, in particular, to drive the vehicle by means of an electric motor. Background technique [0002] Previously known energy storage cells generally have a hard casing. Such hard cases consist at least of an outer shell and a cover which seals the outer shell hermetically. Inside the housing are electrochemical components, for example, formed as electrode coils. The electrochemical element has two current collectors, which lead through the cover to the surface of the accumulator cell. The cover is usually welded to the housing. The arrangement of the weld seam between the cover and the housing is relatively complex, since the weld seam has to be arranged very precisely so that its sides do not protrude from the housing. Generally, several accumulator c...
