When sodium-sulphur cells are subjected to repeated charge/discharge cycles at a relatively high constant current density (100 mA/cm 2 ) a considerable variation in charge acceptance can be obtained. This contrasts sharply with the cycling behaviour at constant voltage. The reasons for this are not
Expressions are derived for the emf of the sodium-sulphur cell in the fully charged state (Et) and in a partly discharged state (El). It is shown that (& -El) is related to the variation of sulphur activity with the composition of the sodium polysulphide melt produced in the cell reaction, and that
