钠硫电池及其储能应用

钠硫电池是以Na-beta-氧化铝为电解质和隔膜,并分别以金属钠和多硫化钠为负极和正极的二次电池,钠硫电池用于储能具有独到的优势,主要体现在原材料和制备成本低、能量和功率密度大、效率高、不受场地限制、维护方便等方面。钠硫电池已经成功的用于削峰填谷、应急电源、风力发电等可再生能源的稳定输出以及提高电力质量等方面。目前在国外已有100余座钠硫电池储能电站在运行中,涉及工业、商业、交通、电力等多个行业,是各种先进二次电池中最为成熟的一种,也是最具有潜力的一种先进储能电池。

Sodium Sulfur Cell and its energy storage application

Sodium sulfur cell was secondary batteries. It used Na-beta-alumina as their electrolytes, sodium metal as cathode, and sodium polysulfide as anode. It had the special advantage of energy storage and reflected in low production cost, high efficiency, easy maintenance and so on. It had been successfully used in steadily outputting renewable resource and improving power quality such as load shifting, emergency power, and wind power generation. At present, there were more than 100 sodium sulfur cell energy storage station, involved in industry, commerce, traffic, and electricity. It was the ripest and the most potential advanced energy storage cell among the secondary batteries.
