Abstract
Sodium‐sulfur cells of the central sulfur configuration, though free from the problems of case corrosion, can still exhibit capacity losses of up to 50% over 100 cycles of operation. This is mainly due to a failure to recharge fully in the two‐phase regime of the operating cycle. This paper describes an investigation of the relationship between rechargeability and the surface properties of the carbon matrix employed as the current‐collecting member in the sulfur electrode. The influence of cell constructional variants is also considered.
