Zinc/bromine battery technology is being developed for use inelectric vehicles, and for electric utility load leveling applications.The authors describe the zinc/bromine system and discuss its performancecharacteristics. The bipolar electrode design gives 2-3 times the energystorage of existing lead acid batteries and is capable of deliveringpower densities as high as 200 W/kg. The electrolyte is circulated toreduce self-discharge of the battery and to improve the thermalmanagement of the system. The battery operates at room temperature,consists of nearly all plastic parts, uses conventional molding andplastic joining methods for construction, and is almost totallyrecyclable. Zinc/bromine is a low cost, rechargeable system with apotentially long cycle life. Recent advances made in computer modelingof this technology are also reported
