Abstract: The thickness of a terminal connection portion of a positive electrode current collector is greater than that of a terminal connection portion of a negative electrode current collector. The terminal connection portion of the positive electrode current collector has a through-hole, and a positive electrode terminal is inserted into the through-hole and is upset on the terminal connection portion. The terminal connection portion of the negative electrode current collector has a through-hole, and a negative electrode terminal is inserted into the through-hole and is upset on the terminal connection portion. A recessed portion is formed in a lower surface of the positive electrode terminal connection portion around the through-hole, and a lower end portion of the positive electrode terminal is disposed in the recessed portion.

Abstract: The invention relates to a battery cell, in particular a lithium-ion battery cell, wherein a cover plate (23) forming a part of a battery cell housing, which is designed as a plane sheet in a conventional manner, is modified to avoid short circuits between the poles of the battery cell due to moisture, for example. To this end, the cover plate (23) is provided with a central area (33) and an edge area (35) surrounding said central area (33). The central area (33) is located above an opening (14) to be closed off by the cover plate (23) of a container (13) forming a part of the battery cell housing, whereas the edge area (35) extends inside said opening (14). Thus, occurring moisture can drain off the platform-like raised central area (33) sideways toward a channel (37) in the edge area (35), and evaporate from there.
