Abstract
An electrochemical energy store with an anode, which is electrically connected to an anode space in which an anode material with a first fill level is arranged, and a cathode, which is electrically connected to a cathode space in which a cathode material with a second fill level is arranged, and an ion-conducting separator, which separates the anode space from the cathode space. The ion-conducting separator has a top region and a base region, wherein at least one conductivity section is provided in the top region of the ion-conducting separator, which conductivity section has greater electrical conductivity during correct operation of the electrochemical energy store than an electrically insulating insulation section in the base region, wherein at least one state of charge of the electrochemical energy store exists in which the anode material makes contact with the conductivity section in the anode space.
