Popis: Two types of secondary zinc cell have been evaluated in our laboratory to assess their suitability to power an electric van. Single cells were charged and discharged with constant-current cycles as well as with controlled-power discharge profiles, scaled to the predicted mass of a full-size battery. Both cells were able to meet the requirements for power discharge specified by the so-called Simplified Federal Urban Driving Schedule (SFUDS) early in life (the first 15 cycles). The Zn/air cell achieved an average of 72 SFUDS repetions (7.2 h) per discharge. The Zn/NiOOH cell achieved an average of 51 SFUDS repetitions (5.1 h) per discharge. The bifunctional air electrodes did not reach oxygen-evolution potentials during the 8-s regenerative breaking portions of the SFUDS cycle.
