    • A half-cell of an electric storage cell comprises an electrocatalytic electrode immersed in an aqueous salt solution of potassium and/or other polysulfide anions in high concentration so that the sulfur species which may be electrochemically oxidized or reduced form substantial components of the solution (e.g. at least 20% by weight). Na.sup.+ and OH.sup.- salts which limit polysulfide solubility and/or solution stability are not added to the salt solution. Aqueous Ks.sub.x.sup.-2 in the storage cell contains up to 24.5 molal reducible sulfur at 25.degree. C., and up to 34.2 molal reducible sulfur in solution at 70.degree. C. This high faradaic capacity is readily accessible at high current density with minimal polarization losses.
    • 蓄电池的半电池包括以高浓度浸入钾和/或其它多硫化物阴离子的盐水溶液中的电催化电极,使得可被电化学氧化或还原的硫物质形成溶液的实质组分(例如 至少20重量%)。 不向盐溶液中加入限制多硫化物溶解度和/或溶液稳定性的Na +和OH-盐。 储存池中的Ksx-2水溶液在25℃下含有最多24.5摩尔可还原的硫,在70℃溶液中含有高达34.2摩尔的可还原的硫。这种高法拉第容量容易在高电流密度下获得,极少的极化损失 。
