ABSTRACT

The sodium-sulfur batteries which operate at 350oC have been mainly used in the field of energy storagesystem. This batteries consist of liquid sodium anode, sulfur cathode and β''-alumina solid electrolyte. The conditioningprocess for stabilization of the batteries is essential since the cells show considerable fluctuation of discharge voltage at thebeginning of discharge/charge cycles. It is found that one of the reasons of the fluctuation is the gradual change of contactarea between molten sodium and solid electrolyte.
