Rechargeable electrochemical battery

摘要

The battery cell has a negative electrode, an electrolyte and a positive electrode, where the cell has a porous structure containing an active mass (17) of the positive electrode. The porous structure is arranged in a substrate vicinity of the negative electrode in such a manner that a part of an active metal (24) resulting from electrode reaction in the negative electrode penetrates into a pore (14) of the active mass of the positive electrode. The active metal is partially deposited in the pore in metallic form.
