从原理来看，钠电池的耐寒性优势源于其独特的化学特性。一方面，钠离子半径比锂离子大，电解液中钠离子迁移时受低温影响更小，且钠电池 常用的电解液凝固点更低，-40℃下仍能保持良好的离子传导性；另一方面，钠电池负极多采用硬碳材料，其晶体结构更稳定。相比之下，传统锂 电池在-20℃环境下容量保持率普遍不足70%，还需额外配备复杂的热管理系统，既增加成本又消耗电量。 锂价连涨 钠电池迎来发展机遇 零下30摄氏度的内蒙古牙克石冬测冰面上，一辆搭载钠离子电池的长安汽车一圈圈平稳行驶，持续验证着电池在极寒环境下的性能稳定性。进入 2026年，钠离子电池在动力电池领域的商用落地喜讯不断：1月，宁德时代发布首款应用于轻型商用车的量产钠离子电池；2月，全球首款钠电量 产乘用车亮相并计划今年上市。 与此同时，近两年钠离子电池在储能领域的商用项目也持续落地。多位行业专家判断，2026年或将成为钠离子电池加速规模化商用的关键节点， 而从长远发展来看，钠电池与锂电池的竞争已不再是"非此即彼"的替代关系，"钠锂双星"交相辉映的格局正逐渐成为行业共识。 商用破局 耐寒成钠电池"敲门砖" 在钠离子电池的商用突破中，"耐寒"特性成为其打开市场的关 ...

行业专家指出，钠离子电池依靠钠离子在正负极之间的迁移实现充放电，具备资源储量丰富、制造成本低廉、循环寿命长及安全性高等 突出优势，是极具发展潜力的新一代电化学储能技术路线。 2月5日，在零下36摄氏度的内蒙古牙克石市，长安汽车与宁德时代联合举办的"长安汽车天枢智能新安全成果发布暨钠电战略全球发布 会"盛大开幕。会上，长安汽车正式发布了全球钠电战略，首款量产钠电池汽车也同步亮相。 长安汽车宣布，旗下阿维塔、深蓝、启源、引力等多个品牌未来都将搭载宁德时代的"钠新"电池。作为宁德时代的钠电池品牌，"钠 新"计划在2 02 6年于换电、乘用车、商用车、储能等领域实现规模化应用，推动钠电时代的进程。 据悉，此次发布的钠电池汽车已在牙克石完成冬季标定测试，其续航里程、低温性能、安全性和放电性能等关键指标均已完全满足用户 日常使用需求。这标志着钠离子电池技术实现了从实验室研发到规模化商业应用的关键突破。这款全球首款钠电量产乘用车预计将于 2026年年中正式上市，接受市场检验。 政策持续加码，钠电池跻身国家战略前沿 尽管钠电池汽车近期才进入公众视野，但钠离子技术早已被纳入国家顶层设计。自2022年《"十四五"能源领域科技创新 ...
