废旧钠离子电池是危废吗？

Is waste Sodium-ion Battery a hazardous waste?    

废旧钠离子电池属于可回收利用的动力电池废弃物，不属于剧毒、高污染的危险废物，环保性远超铅酸电池和部分锂电池。首先，钠电池核心材料不含钴、镍、铅、汞、镉等有毒有害重金属物质，无腐蚀性电解液，原材料无毒无害，废旧电池不会产生剧毒、高污染的废弃物；其次，钠电池废旧电芯可实现正负极材料、金属基材、电解液的高效回收再生，资源利用率高，二次污染小，属于可循环利用的绿色废弃物；第三，钠电池废旧电池的回收、处理、再生过程无高污染、高排放工序，对环境的影响极小，符合环保要求。但需要注意的是，废旧钠电池仍属于动力电池废弃物，需由具备资质的专业回收企业进行合规回收、拆解、再生，严禁个人私自拆解、丢弃，避免造成环境污染和安全隐患。

Waste Sodium-ion Battery belongs to recyclable power battery waste, not highly toxic and highly polluting hazardous waste, and its environmental protection is far better than that of lead-acid batteries and some lithium batteries. First of all, the core materials of sodium batteries do not contain toxic and harmful heavy metal substances such as cobalt, nickel, lead, mercury and cadmium, and have no corrosive electrolyte. The raw materials are non-toxic and harmless, and the waste batteries will not produce highly toxic and highly polluting waste; secondly, the waste sodium battery cells can realize efficient recycling and regeneration of cathode and anode materials, metal substrates and electrolytes, with high resource utilization rate and small secondary pollution, belonging to recyclable green waste; thirdly, the recycling, treatment and regeneration process of waste sodium batteries has no high pollution and high emission processes, and has minimal impact on the environment, which meets the environmental protection requirements. However, it should be noted that waste sodium batteries still belong to power battery waste, which need to be recycled, disassembled and regenerated by professional recycling enterprises with qualifications. It is strictly prohibited for individuals to disassemble and discard them without permission to avoid environmental pollution and potential safety hazards.
