Alkali metal-sulphur cells

摘要

An arrangement for controlling the charge and/or discharge cycles of an alkali-metal/sulphur cell or battery has detecting means for detecting predetermined high and/or low levels of alkali-metal in the anode compartment of a cell or in an alkali-metal reservoir communicating with the anode compartment whereby the end of the charge and/or discharge cycles is determined. Alternatively, similar detecting means can be associated with an alkali-metal/alkali-metal cycling device which is connected electrically in series with a group of series-connected cells of an alkali-metal/sulphur battery to determine the end of the charge and/or discharge cycles of the battery.
