摘要： Alkali metals and sulfur may be recovered from alkali polysulfides in an electrolytic process that utilizes an electrolytic cell (200) having an alkali ion conductive membrane. An anolyte solution includes an alkali polysulfide and a solvent that dissolves elemental sulfur. A catholyte solution includes alkali metal ions and a catholyte solvent. Applying an electric current oxidizes sulfur in the anolyte compartment (206), causes alkali metal ions (210) to pass through the alkali ion conductive membrane to the catholyte compartment (204), and reduces the alkali metal ions (210)in the catholyte compartment (204). Sulfur is recovered by removing and cooling a portion of the anolyte solution to precipitate solid phase sulfur. Operating the cell at low temperature causes elemental alkali metal (222) to plate onto the cathode (220). The cathode (220) may be removed to recover the alkali metal (222) in batch mode or configured as a flexible band to continuously loop outside the catholyte compartment (204) to remove the alkali metal (222).
摘要翻译：碱金属和硫可以在利用具有碱离子传导膜的电解池（200）的电解方法中从碱性多硫化物中回收。阳极电解液包括碱性多硫化物和溶解元素硫的溶剂。阴极电解液包括碱金属离子和阴极电解质溶剂。施加电流在阳极电解液室（206）中氧化硫，使碱金属离子（210）通过碱金属离子传导膜到达阴极电解液室（204），并且减少阴极电解液室中的碱金属离子（210）（204）。通过除去和冷却一部分阳极电解液以沉淀固相硫来回收硫。在低温下操作电池会使元素碱金属（222）镀在阴极（220）上。可以除去阴极（220）以以间歇模式回收碱金属（222）或构造为柔性带，以连续地环绕阴极电解液室（204）外部以除去碱金属（222）。
