Research on electrodes and electrolyte for the Ford sodium-sulfur battery. Annual report, 30 Jun 1974--29 Jun 1975

Technical Report ·
OSTI ID:7343561
Significant research findings are reported on (1) the development of a binder system for extrusion and the preliminary extrusion of conductive beta'-Al/sub 2/O/sub 3/ tubing, (2) rapid sinter techniques in open-air environments at 1550-1600C in which soda evaporation is not a serious problem, (3) the hot-pressing of fine-grained (2-3 micrometers), high strength (35,000-40,000 psi), and low resistivity ((5 ohm-cm) polycrystalline beta'-Al/sub 2/O/sub 3/, (4) the relationship between strength and microstructural variables such as grain size and porosity and (5) the durability of ceramic in Na-Na cells run at high current densities. In the sulfur electrode development program, all work is proceeding on schedule. The sulfur-polysulfide melt was observed at 300C on both charge and discharge in the two-phase region. Both Al/sub 2/O/sub 3/ and MoS/sub 2/ have been found to be stable in Na/sub 2/S/sub 4/ melts at 400C. (GRA)
