What are the economic and social benefits of lithium battery recycling? Lithium battery recycling market space is huge, in line with the degree of energy decay of the battery for secondary use, such as lithium iron phosphate batteries, ternary material batteries, scientific and effective treatment and disposal, not only has a good environmental benefits, but also has obvious economic benefits.
What are the economic benefits of recycling lithium batteries?
With the growth of the use of time, the capacity, discharge efficiency and safety of lithium batteries and other aspects of performance will be a significant decline. For lithium batteries that can no longer meet the current application needs, recycling can effectively play its \"residual value\".
With the arrival of the power battery retirement period, lithium recycling industry is also expected to gradually develop. In addition to policy support, the environmental benefits of lithium recycling and economic benefits are the other two main drivers. On the one hand, the heavy metals and
other harmful substances contained in lithium batteries will not only adversely affect the quality of the environment, but may also pose a great threat to human health. On the other hand, the recycling of lithium is beneficial to the recycling of lithium, cobalt, lithium and other valuable metals, and is an effective means to avoid the risk of shortage of raw materials for batteries, and the economic benefits are very significant.
Analyzed from the economic point of view, the value of recovering Li, Ni, Co, Mn and other metals after disassembly of retired ternary lithium batteries is greater than the cost of recycling and disposal, and has a better recycling value. Take the recycling treatment of LiNi1/3Co1/3Mn1/3O2 ternary retired batteries as an example, refer to the recycling process of industrial wet recovery of valuable metals: disassembly of retired batteries alkali-soluble acid leaching
co-precipitation preparation of precursors to synthesize ternary battery materials, the final is the ternary material as a recycling product.
At present, the recycling of retired ternary lithium batteries is still relatively substantial profits, and the future development trend of the ternary material system is better, with the gradual expansion of the proportion of ternary
materials, the rise of valuable metal raw materials, while recycling technology tends to mature, ternary material recycling will have better economic value.
The cobalt, nickel, manganese, lithium and other precious metals recovered from used lithium batteries can bring considerable economic benefits to the recycling body, especially when the supply of cobalt and lithium resources is tight and the market demand is continuously increasing, the recycling of used lithium batteries will bring good economic benefits to the recycling enterprises.
In addition, the resource-based recycling of lithium batteries can effectively recover the cost of lithium batteries, which has a strong economy. The core in the power battery cost accounted for 36%, if you deduct the gross profit then the core accounted for up to 49%; in consumer batteries the cost of the core accounted for an even higher percentage. In the battery cell, the cost of cathode materials rich in nickel, cobalt, manganese and other metal elements accounted for 45%. Through raw material recycling, nickel cobalt manganese and other metal elements can achieve a recovery rate of more than 95%, while the recovery rate of lithium elements is also above 70%, with significant economic benefits.
What are the social benefits of lithium battery recycling and reuse?
The state supports the scientific and technological research on the recycling of power lithium batteries, guides the collaboration of industry, academia and research, encourages the gradual utilization and recycling, adheres to the concept of the whole life cycle of the product, follows the principle of organic unity of environmental benefits, social benefits and economic benefits, and gives full play to the market.
The end-of-life lithium batteries are used to set up storage systems for solar power generation and wind power generation, which is one of the more popular application directions. The emergence of lithium battery recycling equipment, a powerful solution to a large number of waste lithium batteries, compared to the commonly used waste lithium battery treatment methods (wet metallurgy, pyrometallurgy), lithium battery recycling equipment without the use of chemical reagents, and lower energy consumption, is a friendly to the environment, air, soil and more efficient recycling methods.
Engineers will use instruments and equipment to test the retired power batteries first, screen out the better battery
modules or single cells, divide the levels according to certain rules, and then carry out laddering. A part of the battery modules in better condition will be used in electric boat applications, communication energy storage applications, backup power applications, agricultural machinery and other fields after they are reassembled.
The recycling of retired power lithium batteries will be a very important field, and recycling is of great significance for environmental protection, the whole life cycle economic benefits of lithium batteries, and resource reuse. At present, more and more enterprises have started to study and layout power battery recycling and gradient utilization. This will promote the good development of the power battery industry.
In the future, with the improvement of market and policy, the recycling and reuse of lithium batteries will be higher. The power battery recycling market will also enter the fast lane, and the future power lithium battery recycling market will be a blue ocean.

锂电池回收再利用有哪些经济效益及社会效益？锂电池回收市场空间巨大，对符合能量衰减程度的电池进行梯次利用，如磷酸铁锂类电池、三元材料类电池，进行科学有效的处理处置，不仅具有良好
的环境效益，还具有明显的经济效益。
锂电池回收再利用有哪些经济效益?
随着使用时间的增长，锂电池的容量、放电效率以及安全性等各方面性能均会出现明显下滑。对于已经不能满足当前应用需求的锂电池，回收可以有效发挥其“剩余价值”。
随着动力电池退役期的到来，锂电回收产业也有望逐渐发展起来。除了政策支持，锂电回收的环保效益和经济效益是另外两大主要动力。一方面，锂电池中含有的重金属和其他有害物质，不仅会对环境质量造成不利影响，还可能对人类的健康造成极大的威胁。另一方面，锂电的回收有利于锂、钴、锂等有价金属的循环再利用，是规避电池原料短缺风险的有效手段，经济效益十分显著。
从经济性角度来分析，退役三元锂电池拆解后回收Li、Ni、Co、Mn等金属的价值大于回收处置成本，具有较好的回收价值。以回收处理LiNi1/3Co1/3Mn1/3O2三元退役电池为例，参考工业湿法回收有价金属的回收流程：退役电池拆解碱溶酸浸共沉淀制备前体合成三元电池材料，最终是以三元材料为回收产品。
目前，回收处理退役三元锂电池的利润还是比较可观的，且未来三元材料体系的发展趋势较好，随着三元材料的占比逐渐扩张，有价金属原材料的上涨，同时回收技术趋于成熟化，三元材料回收将具有更好的经济价值。
从废旧动力锂电池中可回收的钴、镍、锰、锂等贵重金属可为回收主体带来可观的经济效益，尤其是当钴、锂资源供应紧张而市场需
求量又在持续增加的情况下，废旧锂电池的回收将为回收企业带来良好的经济效益。
另外，锂电池的资源化回收可以有效收回锂电池成本，具有较强的经济性。电芯在动力电池成本中占比达到36%，若扣除毛利则电芯占比高达49%;在消费类电池中电芯成本占比更高。而在电芯中，富含镍钴锰等金属元素的正极材料的成本占到了45%。通过原料回收，镍钴锰等金属元素可实现95%以上的回收率，而锂元素的回收率也在70%以上，经济效益显著。
锂电池回收再利用有哪些社会效益?
国家支持开展动力锂电池回收利用的科学技术研究，引导产学研协作，鼓励开展梯次利用和再生利用，坚持产品全生命周期理念，遵循环境效益、社会效益和经济效益有机统一的原则，充分发挥市场作用。
将报废的锂电池用来组建用于太阳能发电、风力发电的蓄电系统，是当前比较热门的应用方向之一。锂电池回收设备的出现，有力的解决了大量的废弃的锂电池，相比常用的废锂电池处理方法(湿法冶金，火法冶金)，锂电池回收设备无需使用化学试剂，且耗能更低，是一种对环境、空气、土壤友好且效率更高的回收方法。
工程师们会通过仪器设备，对已退役的动力电池先要进行检测，筛选出比较好的电池模块或者单体电芯，按照一定的规则划分出级别，然后进行梯级利用。一部分状态比较好的电池模块将它们重新组合之后，会被运用到电动船应用、通信储能应用、备用电源应用、农用机
械等领域。
退役动力锂电池的回收利用将是一个非常重要的领域，回收利用对于环境保护、锂电池全生命周期经济效益、资源再利用具有重要意义。目前，越来越多企业已经开始研究和布局动力电池回收和梯次利用。这将促进动力电池行业的良好发展。
未来随着市场与政策的完善，锂电池的回收再利用率会更高。动力电池回收市场也将进入快车道，未来的动力锂电池回收市场将是一个蓝海。
