The invention relates to a rechargeable electrochemical battery cell with a housing, a positive electrode (11), a negative electrode (10), and an electrolyte (9) which contains S02 and a conductive salt of the active metal of the cell. At least one of the electrodes contains a binder selected from the group consisting of: binder A, which consists of a polymer that is made of monomer structural units of a conjugated carboxylic acid or the alkaline, alkaline earth metal, or ammonium salt of said conjugated carboxylic acid or a combination thereof, or binder B, which consists of a polymer that is based on monomer styrol and butadiene structural units, or a mixture of binders A and B.
