摘要: The invention relates to a rechargeable electrochemical battery cell. Said cell comprises negative electrode (5), an electrolyte (19) and positive electrode, the (5) having electronically conductive substrate (14), onto which active mass (15) is electrolytically deposited during charging of aim significantly improve operational safety said To achieve this, in contact with (14) has porous structure (16) formed by solid particles (17), configured positioned such way that (15), cell, penetrates from surface into pores (18) latter again therein.
