| 摘要 |
The invention relates to a rechargeable electrochemical battery cell with a negative electrode, an electrolyte and a positive electrode. The negative electrode has an electronically conducting substrate (12), on which an active metal (24) of the negative electrode is deposited electrolytically when the cell is charged. A porous structure (13), which 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 way that the active metal (17), which is deposited during charging of the cell (3), of the negative electrode penetrates the pores (14) of the porous structure (13), which contains the active mass of the positive electrode, and is deposited there again, at least partially in metallic form. |
