Abstract
The invention relates to a rechargeable battery system with a plurality of electrodes in an electrolyte space filled with electrolyte, which can be tapped with the aid of an electrical tap. At least one of the electrodes is constructed as a substantially insoluble electrode of the second type. Said electrode also has a large-pore and small-pore separator arrangement or an electrochemically active coating provided with a surface profile, through which it is possible to reduce at least the structural and/or shape changes of the electrode during cyclic charging and discharging linked with the sinking of mechanically unstable discharge products.
Claims22
Rechargeable battery system comprising:
- at least two electrodes in an electrolyte space filled with electrolyte and which is tapped with the aid of an electrical tap, in which one of the electrodes is constructed as a substantially insoluble electrode of the second type and the electrode of the second type has a separator arrangement surrounding on all sides of the electrode;
- wherein the separator arrangement has at least one small-pored separator and at least one large-pored separator.
