钠电池在北方低温地区有什么优势？

What advantages does Sodium-ion Battery have in northern low temperature areas?    

钠电池在北方低温地区拥有碾压式的性能优势，完美解决了北方地区新能源电池冬季掉电、趴窝的行业痛点。我国北方地区冬季气温普遍低于-10℃，部分严寒地区冬季气温可达-30℃至-40℃，传统磷酸铁锂电池在-20℃环境下容量仅剩余50%左右，极寒环境下无法正常工作，冬季续航大幅缩水，甚至出现无法启动、趴窝的情况。而钠电池在-20℃环境下可保持85%以上的有效容量，-40℃极寒环境中仍可保留60%以上容量，能够稳定充放电、正常输出电力，冬季续航无明显缩水，无论是北方地区的电动车、户外储能，还是电网储能项目，钠电池都能完美适配，是北方低温地区新能源电池的首选品类。

Sodium-ion Battery has overwhelming performance advantages in northern low temperature areas, and perfectly solves the industry pain point of new energy batteries losing power and breaking down in winter in northern areas. The winter temperature in northern China is generally lower than -10℃, and the winter temperature in some severe cold areas can reach -30℃ to -40℃. Traditional lithium iron phosphate batteries only retain about 50% of their capacity at -20℃, and cannot work normally in extremely cold environments, resulting in a significant reduction in battery life in winter, and even the inability to start and break down. While sodium batteries can maintain more than 85% of their effective capacity at -20℃, and still retain more than 60% of their capacity in the extremely cold environment of -40℃, and can stably charge and discharge and output power normally, with no significant reduction in battery life in winter. Whether it is electric vehicles, outdoor energy storage, or grid energy storage projects in northern areas, sodium batteries can be perfectly adapted, and are the preferred category of new energy batteries in northern low temperature areas.
