Abstract

An energy store is provided having a first electrode, a second electrode, an electrolyte in between, a first redox pair having a first oxidation reactant and a first oxidation product, and a housing, wherein a fluidic redox pair is present in the housing and comprises a fluidic oxidation reactant and a fluidic oxidation product, wherein during the discharge of the energy store, the fluidic oxidation product is reduced, and wherein during the charging of the energy store, the fluidic oxidation reactant is oxidized, wherein the fluidic redox pair in the housing is gaseous, and a pump or a compressor is adapted such that the fluidic redox pair within the housing is held at a pressure which is above the ambient pressure outside the housing. A method for charging or discharging an energy store is also provided.
