摘　　要：为了提高钠硫电池的安全性,从单体电池结构、成组技术、安全防护、监测控制四个方面对钠硫电池安全性的影响因素进行了分析。分析结果表明,通过增加安全管来优化单体纳硫电池的结构,能够使单体钠硫电池在发生β氧化铝陶瓷管破损的极端情况下外观完好,无活性物质泄漏。应用云母防火、干沙吸收、分区隔离等成组技术,可以进一步提高钠硫电池的安全性。对钠硫电池保温箱进行自由跌落试验、面倾跌试验、角倾跌试验、翻倒试验、地震试验,确认钠硫电池保温箱能够承受误操作和突发灾害等造成的损坏。通过电池管理系统对钠硫电池的温度、电压、电流进行实时监测与控制,是确保钠硫电池安全稳定运行的关键因素。In order to improve the safety of the sodium-sulfur battery, the factors affecting the safety of the sodium-sulfur battery were analyzed from four aspects - single battery structure, group technology, safety protection, and monitoring control.The analysis results show that by adding a safety tube to optimize the structure of a single sodium-sulfur battery, the single sodium-sulfur battery can have a good appearance and no active material leakage under extreme damage conditions of beta alumina ceramic tube.The application of group technologies such as mica fire prevention, dry sand absorption, and partition isolation can further improve the safety of the sodium-sulfur battery.Through free drop test, face drop test, angular drop test, tip-over test, earthquake test, it confirms that the sodium-sulfur battery cooler box can withstand the damage caused by mis-operation and sudden disasters.Real-time monitoring and control of the temperature, voltage, and current of the sodium-sulfur battery through the battery management system is a key factor to ensure the safe and stable operation of the sodium-sulfur battery.
