钠电池可以低温充电吗？

Can Sodium-ion Battery be charged at low temperature?    

钠离子电池完全支持低温充电，低温充电性能远超锂电池，是其核心优势之一。传统磷酸铁锂电池在低温环境下充电，锂离子嵌入难度大幅提升，充电速度大幅减慢，充电容量大幅下降，甚至出现无法充电、电池损坏的情况，冬季户外充电极为不便。而钠电池电解液配方专为低温环境优化，钠离子在低温环境下仍具备优异的迁移能力，电极材料对钠离子的嵌入脱嵌阻力小，低温充电性能优异。实测数据显示，钠电池在-20℃的低温环境下，仍可实现正常的1C倍率充电，充电容量和充电速度与常温环境相比无明显下降；在-40℃的极寒环境中，仍可实现0.5C倍率的正常充电，完全满足冬季户外、低温地区的充电需求，解决了新能源电池冬季充电难的行业痛点。

Sodium-ion Battery fully supports low temperature charging, and its low temperature charging performance is far better than that of lithium batteries, which is one of its core advantages. Traditional lithium iron phosphate batteries have greatly reduced lithium ion intercalation difficulty, charging speed and charging capacity in low temperature environments, and even cannot be charged or the battery is damaged, which makes outdoor charging in winter extremely inconvenient. While the electrolyte formula of sodium batteries is specially optimized for low temperature environments. Sodium ions still have excellent migration ability in low temperature environments, and the intercalation and deintercalation resistance of sodium ions in electrode materials is small, so the low temperature charging performance is excellent. Measured data shows that sodium batteries can still achieve normal 1C rate charging at -20℃, and the charging capacity and charging speed are not significantly reduced compared with normal temperature environments; in the extremely cold environment of -40℃, they can still achieve normal 0.5C rate charging, which fully meets the charging needs of outdoor and low temperature areas in winter, and solves the industry pain point of difficult charging of new energy batteries in winter.
