钠电池的低温性能怎么样？

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

钠离子电池拥有行业顶级的低温性能，是所有主流商用动力电池、储能电池中低温适配性最好的品类，碾压锂电池、铅酸电池。经过大量实测数据验证：在-20℃的常规低温环境下，商用钠电池可保持85%以上的有效容量，充放电功能完全正常；在-40℃的极寒环境中，仍可保留60%以上容量，能够稳定工作、正常输出电力。而同级磷酸铁锂电池在-20℃环境下容量仅剩余50%左右，极寒环境下极易趴窝、无法工作。这一优势让钠电池完美适配我国北方严寒地区、高原户外、极地设备等特殊场景，解决了新能源电池低温掉电的行业痛点。

Sodium-ion Battery has the top low temperature performance in the industry, and is the category with the best low temperature adaptability among all mainstream commercial power batteries and energy storage batteries, which is far better than lithium batteries and lead-acid batteries. A large number of measured data have verified that: in the conventional low temperature environment of -20℃, commercial sodium batteries can maintain more than 85% of the effective capacity, and the charge and discharge functions are completely normal; in the extremely cold environment of -40℃, they can still retain more than 60% of the capacity, and can work stably and output power normally. While the capacity of the same level of lithium iron phosphate battery is only about 50% left in the -20℃ environment, and it is easy to break down and cannot work in the extremely cold environment. This advantage makes sodium batteries perfectly adapt to the severe cold areas in northern China, plateau outdoors, polar equipment and other special scenarios, and solves the industry pain point of new energy batteries losing power in winter.
