Abstract
The invention relates to a rechargeable electrochemical battery cell having a negative electrode, an electrolyte, and a positive electrode. The negative electrode comprises an electronically conductive substrate (12) at which an active metal (24) of the negative electrode is deposited by electrolysis during the charging of the cell. A porous structure (13) that contains the active mass (17) of the positive electrode is arranged in the vicinity of the substrate (12) of the negative electrode (5) in such a manner that the active metal (17) of the negative electrode that is deposited during the charging of the cell (3) penetrates into the pores (14) of the porous structure (13) comprising the active mass of the positive electrode and is deposited further therein, at least in part, in metallic form.
