钠电池高温性能怎么样？

How is the high temperature performance of Sodium-ion Battery?    

钠离子电池常温工作性能极致稳定，常规高温环境适配性良好，极端高温下略有衰减，整体性能符合民用和工业标准。在0℃-45℃的常规工作温度区间内，钠电池充放电稳定、容量无明显衰减、安全性能优异，完全适配日常户外、室内、工业场景。当环境温度长期超过55℃的极端高温工况时，电池内部电解液活性增强，轻微副反应增多，电极材料老化速度加快，容量衰减速率会小幅提升，长期高温运行会缩短电池使用寿命。但相较于铅酸电池、部分普通锂电池，钠电池的高温稳定性仍更优，日常使用无需担心高温故障。

Sodium-ion Battery has extremely stable working performance at room temperature, good adaptability to conventional high temperature environment, and slight attenuation under extreme high temperature, and the overall performance meets the civil and industrial standards. In the conventional working temperature range of 0℃-45℃, the sodium battery has stable charge and discharge, no obvious capacity attenuation, and excellent safety performance, which fully adapts to the daily outdoor, indoor and industrial scenarios. When the ambient temperature exceeds 55℃ for a long time in extreme high temperature conditions, the activity of the electrolyte inside the battery increases, the slight side reactions increase, the aging speed of the electrode material accelerates, and the capacity attenuation rate will increase slightly, and long-term high temperature operation will shorten the service life of the battery. However, compared with lead-acid batteries and some ordinary lithium batteries, the high temperature stability of sodium batteries is still better, and there is no need to worry about high temperature failure in daily use.
