| 摘要 |
The invention relates to an energy storage device comprising an electrode winding (12) with at least one winding layer (30) wound around a winding core (13), said winding layer comprising an anode layer, a cathode layer, a separator layer that is arranged between the anode layer and the cathode layer and can accommodate an electrolyte, and an insulation layer provided on the anode layer and/or cathode layer, or the invention relates to an electrode stack having a plurality of stack layers which comprise in each case an anode layer, a cathode layer, a separator layer which is arranged between the anode layer and the cathode layer and can accommodate an electrolyte, and an insulation layer provided on the anode layer and/or cathode layer. In order to ensure an enhanced functional reliability while keeping the structure simple, at least one inner functional layer (40) is arranged in the winding core (13) or between two stack layers which are provided in the interior, in particular in the central region of the electrode stack, said functional layer comprising a carrier layer that is at least partially permeable to substances. |
