| dc.description.abstract | The redox behavior of Cu2S in a Li2S-dissolving aprotic electrolyte was investigated to examine the practical viability of rechargeable batteries using sulfide ions as carrier ions. We established aprotic electrolytes, dimethyl sulfoxide and dimethylformamide containing S2- at over 0.10 M concentration by adding NH4NO3 to increase the solubility of Li2S, which is hardly soluble in almost all aprotic solvents. Two redox reactions of Cu2S, Cu/Cu2S and Cu2S/CuS, were observed at -0.25 V and 0.60 V vs Mo, respectively. In addition, it was found that elemental S is electrodeposited/stripped at approximately 0.1 V vs Mo on graphite but not on platinum. | en_US |
