Primary SS + Li/Li-glass/S + C + Al + SS cell. a discharge cycle. S8 is not reduced while the cell voltage varies from 2.51 to 2.36 V; in this voltage range, Li was plated. From 2.36 to 1.3 V, S8 reduction occurs. The S8 reduced corresponded to around 1/10 of the S8 in the positive electrode. b Photograph of the positive electrode on the paper matrix containing the Li-glass electrolyte; lithium of the negative electrode (not shown) is on the opposite side of the glass-on-paper. c The removed Al-positive electrode current collector
