Abstract (en)
[origin: WO2021037991A1] The invention proceeds from an electrochemical energy storage device, in particular an electrochemical cell (10), based on the redox system Na/MCl2 comprising a ceramic electrolyte (12) that conducts Na+ ions and a salt as liquid electrolyte, wherein a cathode space (11) is arranged outside an electrolyte tube and an anode space (13) is arranged within an electrolyte tube. The invention proposes that the electrochemical energy storage device, in particular the electrochemical cell, comprises a cell housing (19) which has a semi-spherical cell bottom (23).
