The invention relates to a battery cell (101; 101; 101''; 101'''), comprising a first electrode foil (102) and a second electrode foil (103), which are rolled up together with an interposed separator to form a roll 104; 104'''), a first (105; 105''; 105''') and a second terminal connector (106; 106''; 106''') for connecting the battery cell (101; 101; 101''; 101') to external circuitry, a first connecting element (107; 107; 107'), which electrically connects the first terminal connector (105; 105''; 105''') to the first electrode foil (102), and a second connecting element (108; 108; 108'''), which electrically connects the second terminal connector (106; 106''; 106') to the second electrode foil (103). According to the invention, the two connecting elements (105, 107; 105'', 107''; 105''', 107''') make contact with the respective electrode foil (102; 103) on a first end face (110; 110') of the roll.
