The effects of pH on sulfur-induced passivity degradation of Alloy 800 in simulated crevice chemistries were evaluated using electrochemical impedance spectroscopy (EIS), secondary ion mass spectroscopy (SIMS), and Mott-Schottky analysis methods. Experimental results reveal that the detrimental effect of impurities containing sulfur at the reduced or intermediate oxidation level (S x ) on the passivity of Alloy 800 depends significantly on the solution pH. In neutral crevice (NC) chemistry containing chloride ions, the S x obstructs the healing process during repassivation, retards the dehydration reaction and also incorporates H, -OH and S into the passive film. However, the detrimental effect of S x is insignificant in an alkaline crevice (AKC) solution due to a change in surface adsorption and surface charge. Impurities containing sulfur at the reduced or intermediate oxidation level would cause Alloy 800 to lose its passivity and become active in an acidic crevice (AC) chemistry. Experimental evidence also indicates that the solution pH alters the semiconductor type of the surface film -from n-type in NC solution to p-type in AKC solution.

“…ΔG f o = 439.084 kJ/mol [17]; the theoretical open circuit voltage was 2.27 V. The low plateau 2.1 V region could be explained by the formation of Li 2 S. However, the higher plateau 2.4 V region is likely not related with the formation Li 2 S. Hemmingsen [21] reported that the theoretical OCP (open circuit potential) of polysulfide, Li 2 S n (n>1), was higher than Li 2 S. The high potential plateau might be related with the formation of Li 2 S n (n>1). Furthermore, Kim et al [9] argued that Li 2 S n would be formed first in the upper plateau region after which Li 2 S would be formed.…”

The lithium/sulfur cell is very attractive because of its high theoretical specific capacity and low production cost. The sulfur electrode is prepared from sulfur, with carbon as an electronic conductor and PEO as an ionic conductor. We changed the carbon content of a 50 wt.% sulfur electrode from 10 wt.% to 40 wt.%. The lithium/PEO/sulfur cell showed two plateau potential regions (2.4 V, 2.1 V) and high discharge capacity, i.e., 1484 mAh/g (88 % utilization) for optimum composition. The discharge capacity decreased drastically by charge-discharge cycling. The degradation rate as well as the first discharge capacity depended on the composition of the sulfur electrode. The optimum composition of the 50 wt.% sulfur electrode was 30 wt.% carbon and 20 % PEO.

“…Electrochemistry of self-assembled monolayers of thiols on various substrates, particularly gold surfaces, being an extensively investigated field [18]. Much research on sulfur compounds in aqueous media has been reported, [19,20] whilst relatively little, to date, has been presented describing work in organic solvents. Of these, a few concern the reduction of various phenyl thioethers, (RSPh) in polar non-aqueous solvents such as N,N-dimethylformamide (DMF), at platinum, [21] mercury, and glassy carbon electrodes [22][23][24].…”
