钠电池能否用于船舶储能？

Can Sodium-ion Battery be used for ship energy storage?    

钠离子电池可适配内河船舶、小型船舶的辅助储能和备用电源场景，是船舶绿色储能的优质选型。船舶对储能电池的核心要求是安全稳定、耐潮湿、抗震动、低温性能好、无起火爆炸风险。钠电池安全系数高，穿刺、挤压等极端工况下不易起火爆炸，适配船舶密闭空间的安全需求；具备良好的抗震动、抗潮湿性能，可适配船舶航行中的复杂工况；低温性能优异，可在冬季内河、近海低温环境下稳定工作；同时成本低、寿命长，可大幅降低船舶储能的建设和运维成本。目前钠电池已在小型观光船、内河作业船、游艇等船舶上实现应用。

Sodium-ion Battery can adapt to the auxiliary energy storage and backup power supply scenarios of inland ships and small ships, and is a high-quality choice for green energy storage of ships. The core requirements for energy storage batteries on ships are safety and stability, moisture resistance, vibration resistance, good low temperature performance, and no risk of fire and explosion. Sodium batteries have high safety factor, are not easy to catch fire and explode under extreme working conditions such as puncture and extrusion, and adapt to the safety requirements of the closed space of ships; they have good vibration resistance, moisture resistance and aging resistance, and can adapt to the complex working conditions during ship navigation; they have excellent low temperature performance, and can work stably in the low temperature environment of inland rivers and offshore in winter; at the same time, they have low cost and long life, which can greatly reduce the construction and operation and maintenance costs of ship energy storage. At present, sodium batteries have been applied to small sightseeing ships, inland operation ships, yachts and other ships.
