Post-test analysis of positive electrodes from CSPL Beta cells
Conference

OSTI ID:5311083
The post-test examinations conducted on Beta (sodium/sulfur) cells designed for electric-vehicle applications are described. These cells utilized the sulfur core concept and were tested in a horizontal position. The major emphasis of these examinations was to determine: (1) the corrosion of current-collector materials and the associated transport and distribution of corrosion products, (2) the morphology of the sulfur electrode, i.e., microstructure, distribution of sulfur/soldium polysulfide phases, concentration and distribution of voids, and uniformity of the charge/discharge reactions, (3) the identity and extent of reactions with the materials in the glass and thermocompression bond seals, and (4) evidence of degradation of the ..beta..''-Al/sub 2/O/sub 3/ electrolyte. The latter two items are not covered here.
