The zinc/ferro-ferricyanide battery system is intended for utility load leveling and solar photovoltaic/wind applications with advantages of high cyclic efficiency, high cell voltage, random cycling without zinc strip cycles and with switching times of less than 5 ms from load to insolation or vice versa. Self-discharge has been measured at 1.6%/day. The system demonstrates excellent electrochemical performance. Cell voltages are 1.88 V OCV and 1.61 V discharge at 35 mA/cm/sup 2/ or 57 mW/cm/sup 2/ in 2N NaOH at 40/sup 0/C (Nafion N-125 separator). Cell polarization losses are almost entirely resistive and within the separator. Over 800 4-hr cycles have been demonstrated in cell of 60-cm/sup 2/ nominal area (70 mA.h/cm/sup 2/ capacity) with mean energy efficiency of 76.6 + or - 2.1 percent). Similarly, a 60-cm/sup 2/ cell has demonstrated over 220, 11 to 17 hour cycles (255 + or - 48 mA.h/cm/sup 2/ capacity) with a mean energy efficiency of 75.3 + or - 5.1 percent.
