Description
技术领域technical field
本发明涉及废旧锂离子电池回收技术领域，特别涉及正极片活性物质与正极集流体的分离方法。The invention relates to the technical field of recycling waste lithium-ion batteries, in particular to a method for separating positive electrode sheet active materials and positive electrode current collectors.
背景技术Background technique
近年来，随着全球锂离子电池产业的迅猛发展，其产能也在迅速的增长，行业内对相关材料的需求量同样在稳步的增加。特别是近几年来为了应对燃油汽车带来的环境问题，电动汽车成为了未来的重要发展方向，动力锂离子电池因此也迎来了大好的发展机遇。然而，可以预见的是，动力锂离子电池材料的消耗量将可能是传统电池的成千上万倍，甚至其中的锂和钴等金属会出现供不应求的现象。同时，锂离子电池的寿命是有限的，大量锂电池的使用将意味着有大量废旧锂电池的出现。若能够回收废旧电池的有价金属，不仅可以缓解资源紧张，创造巨大的经济价值，还可以解决废旧电池对环境的污染问题。因此，锂离子电池的回收及再利用成为了一个亟待解决的问题。In recent years, with the rapid development of the global lithium-ion battery industry, its production capacity is also increasing rapidly, and the demand for related materials in the industry is also steadily increasing. Especially in recent years, in order to deal with the environmental problems brought by fuel vehicles, electric vehicles have become an important development direction in the future, and power lithium-ion batteries have also ushered in great opportunities for development. However, it is foreseeable that the consumption of power lithium-ion battery materials may be tens of thousands of times that of traditional batteries, and even metals such as lithium and cobalt will be in short supply. At the same time, the life of lithium-ion batteries is limited, and the use of a large number of lithium batteries will mean the emergence of a large number of waste lithium batteries. If the valuable metals of waste batteries can be recovered, it can not only alleviate the shortage of resources, create huge economic value, but also solve the problem of environmental pollution caused by waste batteries. Therefore, the recovery and reuse of lithium-ion batteries has become an urgent problem to be solved.
目前，行业内对废旧电池的回收技术尚处在初级水平，尚且没有一个完善的回收方案。回收方法大都是无差别的将空电态的电池粉碎，然后采用浮选法、磁选法和湿化学法等来分离出目标的有价金属。由于前期没有对电池材料进行分类筛选，导致后期回收处理时步骤繁琐，能耗较高，并且回收效率不高。而事先将电极材料与集流体分离的方法还较少。正极活性物质通常是与溶于NMP的有机粘结剂(如PVDF)匀浆后涂覆在铝集流体上的，综合文献，目前将正极材料与集流体分离的方法主要有去除粘结剂和溶解集流体两种。去除粘结剂的方法往往需要高温处理，对温度的控制很重要，过高或者过低都不行，并且处理过程中有机物的燃烧会造成大气污染；而碱溶解集流体会产生大量的气体，气体会带出一部分碱液，会对环境和人带来一定的伤害，并且这种处理方法并没有达到事先分离的效果，溶解后正极活性物质也混入碱液中，需要额外的分离步骤。因此，目前还没有一种简单有效并兼顾能耗、环保等的分离正极材料和集流体的方法。At present, the recycling technology of used batteries in the industry is still at the primary level, and there is no perfect recycling plan. Most of the recycling methods are indiscriminately crushing the empty battery, and then using flotation, magnetic separation and wet chemical methods to separate the target valuable metals. Because the battery materials were not sorted and screened in the early stage, the steps of recycling in the later stage were cumbersome, the energy consumption was high, and the recycling efficiency was not high. However, there are few ways to separate the electrode material from the current collector in advance. The positive electrode active material is usually coated on the aluminum current collector after being homogenized with an NMP-soluble organic binder (such as PVDF). According to comprehensive literature, the current methods for separating the positive electrode material from the current collector mainly include removing the binder and Dissolves both current collectors. The method of removing the binder often requires high-temperature treatment, and it is very important to control the temperature. It will not work if it is too high or too low, and the combustion of organic matter during the treatment will cause air pollution; and the alkali-dissolved current collector will produce a large amount of gas, gas A part of the lye will be brought out, which will cause certain harm to the environment and people, and this treatment method does not achieve the effect of prior separation. After dissolution, the positive active material is also mixed into the lye, requiring additional separation steps. Therefore, there is currently no simple and effective method for separating cathode materials and current collectors that takes into account energy consumption and environmental protection.
