An investigation of the failure of beta alumina under simulated conditions of sodium/sulphur cell overcharge (TM-MS-042)

It has been proposed that beta alumina failure under conditions of cell overcharge is due to the non-homogeneous operation of the sulphur electrode. Thus, as a cell approaches the fully charged state, a non-conducting layer of sulphur is formed at the beta alumina surface. For constant current charging, which is...
