<p>A circulating electrolyte type secondary battery comprises a stack of secondary cells (1, 2, 3 etc.), each having a cathode (11) and an anode (12), and being divided into respective catholyte chambers (16), and anolyte chambers (17) by separators (13). Catholyte is supplied to each catholyte chamber through respective inlets (25), leaving through respective outlets (33). According to the invention, occurence of abnormal electrodeposition of negatively active material is avoided by providing first and second secondary electrodes (65) and (66) in the vicinity of the catholyte inlet and outlet of a cell at the low potential end of the battery. These secondary electrodes are electrically connected to the cathode terminal of the battery.</p> |
