钠电池进水还能用吗？

Can Sodium-ion Battery still be used after water ingress?    

钠电池进水后能否继续使用，需根据进水的严重程度、进水时间、电池密封情况来判断，核心是避免电池内部短路、腐蚀，保障使用安全。首先，若电池仅为外壳表面轻微进水、溅水，未渗入电池内部，只需及时用干布擦拭干净，放置于阴凉通风处彻底干燥，检查电池外观、电压、充放电功能正常后，即可继续使用，无安全隐患。其次，若电池密封破损，进水已渗入电池内部，需立即停止使用，断开所有接线，严禁充电、放电，避免电池内部短路、腐蚀加剧，甚至出现起火、爆炸风险；随后将电池放置于阴凉通风处彻底干燥，及时联系专业厂家或售后人员，对电池进行全面检测、拆解、维修，确认电池内部无短路、无腐蚀、性能正常后，方可继续使用；若检测发现电池内部已出现短路、腐蚀、性能衰减，需立即报废更换，严禁继续使用。

Whether Sodium-ion Battery can continue to be used after water ingress depends on the severity of water ingress, the duration of water ingress, and the sealing condition of the battery. The core is to avoid internal short circuit and corrosion of the battery, and ensure the safety of use. First of all, if the battery only has slight water ingress or splashing on the surface of the shell, and the water does not penetrate into the inside of the battery, you only need to wipe it clean with a dry cloth, place it in a cool and ventilated place to dry completely, and check that the battery appearance, voltage, charge and discharge functions are normal before continuing to use, without potential safety hazards. Secondly, if the battery seal is damaged and the water has penetrated into the inside of the battery, you need to stop using it immediately, disconnect all wiring, and strictly prohibit charging and discharging to avoid the aggravation of internal short circuit, corrosion, and even the risk of fire and explosion; then place the battery in a cool and ventilated place to dry completely, and contact the professional manufacturer or after-sales personnel in time to conduct a comprehensive inspection, disassembly and maintenance of the battery. Only after confirming that there is no short circuit, corrosion and abnormal performance inside the battery can it continue to be used; if the inspection finds that the inside of the battery has been short-circuited, corroded, or the performance has been attenuated, it needs to be scrapped and replaced immediately, and it is strictly prohibited to continue to use.
