Sodium-sulfur battery and method of making a double carbon mat-composite sulfur electrode for use in sodium-sulfur cells
Patent
·
OSTI ID:5534229
An improved sodium-sulfur cell having a sulfur electrode for a physically-large battery cell comprises in its pre-emplaced condition at temperatures below operating temperature at least one preformed solid composite structure defining a plug conforming to the interior shape of an electrolyte containment structure. The plug segments are constructed of fibrous electrically conductive material in a compressed elastic condition having a relatively thin layer of electrically resistive material along the face of the segment which will confront the electrolyte. The conductive material and the resistive material are permeated with a binder of molten sulfur which has been solidified. The sulfur electrode is adapted to be inserted within a battery cell container and subsequently melted so that the structure can expand and compress against the inner walls of the containment structure.
