摘　　要：为了深入利用可再生能源,迫切需要发展大容量、低成本、高效和安全的能源存储技术。新提出的锌镍单液流电池具有低成本、长循环寿命、高能效的特性,显示出在规模储能方面的潜在优势,为全面了解锌镍单液流电池的特性,需研究其温度适应性。为此,文章采用恒流限压充放电方式研究了不同温度对锌镍单液流电池充放电性能的影响。结果表明,锌镍单液流电池可在-40℃^+40℃范围内工作,充放电库仑效率随着温度降低而提高,能量效率在+40℃^-20℃区间可达到80%以上,-30℃^-40℃能量效率稍低。研究结果为后续研究和应用奠定了基础。To expand the consumption of the intermittent renewable energy resources,the development of large capacity,low cost,highly efficient and safe energy storage devices is the most urgent demand. Zinc-Nickel single-flow batteries with low cost of raw materials,long cycle life and high efficiency,are showing attractive application prospect. In order to fully understand the characteristics of Zinc-Nickel single-flow batteries,the urgent needs are in the research into temperature adaptability of Zinc-Nickel single-flow batteries before practical utilization. In this paper,the effects of temperature on the charge/discharge performance of the Zinc-Nickel single-flow battery（ ZNSFB） are investigated by using constant current charge discharge with limitary charge voltage. The results show that ZNSFB can operate in the temperature range from -40℃ to ＋40℃ with acceptable energy ef ciency. The coulombic ef ciency increases as the temperature decreases;the energy ef ciency of above 80% is obtained in the temperature range of -20℃ to ＋40℃. These results enable us to better evaluate the application prospect of ZNSFBs and lay the foundation for the follow-up research and application.
