Is the safety of Sodium-ion Battery high?
钠离子电池的安全等级极高,属于高安全型新能源电池,热失控风险极低,极端工况稳定性远超三元锂电池,优于普通磷酸铁锂电池。从材料特性来看,钠电池电极材料、电解液化学性质稳定,燃点高、不易分解、不易释放可燃气体;从实测安全测试来看,钠电池可轻松通过穿刺、挤压、重物冲击、过充、短路、高温烘烤等严苛安全测试,极少出现起火、爆炸、剧烈热失控现象。日常商用、工业运行过程中,钠电池鼓包、漏液、自燃的概率极低,容错率高,对使用环境、运维条件要求更低,适合大规模储能电站等密集布置、高安全要求的场景。
Sodium-ion Battery has an extremely high safety level, belonging to the high-safety new energy battery, with extremely low thermal runaway risk, and the stability under extreme working conditions is far better than that of ternary lithium batteries, and superior to that of ordinary lithium iron phosphate batteries. From the perspective of material characteristics, the electrode materials and electrolyte of sodium batteries have stable chemical properties, high ignition point, are not easy to decompose and release flammable gases; from the perspective of measured safety tests, sodium batteries can easily pass strict safety tests such as puncture, extrusion, heavy impact, overcharge, short circuit and high temperature baking, and rarely catch fire, explode or have severe thermal runaway, only slight heating and swelling occur, and there is no risk of severe safety accidents. In the process of daily commercial and industrial operation, the probability of swelling, leakage and spontaneous combustion of sodium batteries is extremely low, with high fault tolerance, and lower requirements for use environment and operation and maintenance conditions, which is suitable for large-scale energy storage power stations and other scenarios with high safety requirements.
