Abstract

An ion-selective separator 37, for a battery having an anode 35 and an alkali metal sulfide or polysulfide cathode. The separator comprises an alkali metal ion conducting separator film 43, such as a polypropene film, for separating the anode and the cathode. The separator further comprises a carbon layer 47 disposed to a cathode side of the film and an alkali metal ion conductor layer 45 disposed to an anode side of the carbon layer. An alkali metal flow battery comprises a flow battery electrochemical cell comprising anode 21 and cathode half-cells 19 separated by an ion-selective separator and having at least one liquid electrode or liquid electrolyte. The battery also comprises at least one electrolyte reservoir (7 13, Fig 1) and a flow circulation system (9, Fig 1). The battery further comprises one or more of the ion-selective separator defined above; an alkali-metal polysulfide catholyte; an anode selected from a solid alkali metal, alkali metal alloy, an alkali metal and/or graphite composition and an alkali-metal based anolyte; an electrolyte flushing system for flushing an electrolyte through the electrochemical cell in a short burst or pulse; a flow circulation system configured to enable circulating electrolyte to pass through a power convertor to act as a coolant for the power convertor; and a dosing and/or filtering system for use with the at least one electrolyte. A method of enhancing performance of an electrolyte in a flow battery comprises dosing the electrolyte with a functional additive.
