The performance of sodium/sulphur cells containing a porous insulating layer between the solid electrolyte and carbon felt matrix (TM-EC-015)

Previous work at British Rail pertaining to the performance of central sulphur sodium/sulphur cells, has highlighted the problem of increase of two-phase recharge resistance with cycling. Under conditions of constant current charging, this phenomenon manifests itself in a decrease in the critical recharge current density above which premature polarisation at...
