Development of sulphur electrode structures which confer resistance to high voltage breakdown to the ceramic electrolyte (TR-EC-022)

The possibility of sodium/sulphur cells polarising to high voltages when charged in a series chain has been appreciated for some time. As discussed previously this results in localised high current densities in. the electrolyte. We have simulated this situation experimentally in Na/beta alumina/Na and Na/beta alumina/NaNO3 tests and demonstrated that...
