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

Ahstraet-The sulphur activity has been measured at 400°C as a function of sulphur mole fraction in a series of molten polysulphides containing lithium and sodium in different proportions. The measurements provide confirmation of the positions of the phase boundaries in the (Li/Na/S) system, and also
Previous voltaiumetric work[1] on the anodic evolution of sulphur has been complemented by a microscopic study of the surfaces of working anodes in a thin-layer cell . The observations confirm the earlier conclusions that the anodic process initially involves the oxidation of polysulphide anions to
