【Abstract】 Sodium polysulfide/bromine (PSB) energy storage battery had advantages of high efficiency, long lifetime, low cost and rapid response. It was suitable for utility scale application. The research and development of key materials and electrolyte management as well as the commercialization progress were summarized. It was pointed out that the key technologies were to (develop) high activity negative electrode with more stable performance, synthesize high selectivity cation exchange membrane with low cost, and reduce the cost depending on mass production. It was expected that the specific power above 50 W/kg and the cost (below) 100 $/kWh could be achieved.更多还原
