Abstract (en)

[origin: WO2013023773A1] The invention relates to an energy storage device comprising at least one energy storage cell having an electrode stack (2) or an electrode winding. In order to ensure an enhanced functional reliability while keeping the structure simple, at least one outer functional layer (10) is provided on at least one outer wall of the energy storage cell, in particular the electrode stack (2) or electrode winding, said outer functional layer comprising a carrier layer that is at least partially permeable to substances.
