The Non-Flowing Zinc/Bromine Battery for Electric Vehicle Applications

摘要

The Non-Flowing Zinc/Bromine Battery technology is a promising spin-off from work on the flowing electrolyte Zinc/Bromine Battery, by ZBB Energy Corporation. The new Non-Flowing Zinc/Bromine Battery (NFZBB) is ideally suited to Electric Vehicle (EV) applications. The advantages offered by the NFZBB are:rnHigh energy density for a long EV driving range;rnHigh power density for good EV acceleration;rnCapacity to withstand several thousand full discharge cycles without damage so that the batteries will last for the life of the vehicle; andrnLow cost production.rnThe paper, the first publication about this new technology, outlines the construction of the battery; it's performance characteristics and the most recent test results. The technology uses multiple cell, bipolar electrode "battery stacks" that can have sixty or more cells giving individual batteries with voltages of over one hundred volts. High voltage vehicle power systems give the advantage of reduced weights and dimensions for the power control, wiring and motor systems. The battery has a simple construction with no electrolyte circulation. A single cell prototype, currently on life cycle test, has passed the 3,300 cycles mark and still achieves very good performance. During this test the battery is fully discharged to 1.0 volt per cell at each cycle.
