Abstract:
A battery cell (1) has electrodes (9), an electrolyte (7) and a housing (3) surrounding the electrodes (9) and the electrolytes (7). The housing (3) is composed of a plurality of housing components (11) adhesively bonded to one another by an adhesive composite (13) along opposite abutment faces (21). The adhesive composite (13) has a first adhesive composite component (15) which is interposed between the opposite abutment faces (21) and which is resistant and impermeable to the electrolyte (9); a second adhesive composite component (17) which is over regions of the two housing components (11) adjacent to the first adhesive composite component (15), and which is composed of a cured material; and a third adhesive composite component (19) which is over regions of the two housing components (11) adjacent to the second adhesive composite component (17) and which is impermeable to water and/or oxygen.
