With the growing voice of lithium battery recycling, we believe that these problems still plague the development of the lithium battery recycling industry. First, the cost of cascade use is higher. According to relevant experts, according to my country's current technology and craftsmanship, the cost of establishing power lithium battery echelon applications does not have a high advantage. In addition, along with the attenuation of power lithium batteries, the service life of power lithium batteries will also be greatly affected. The indirect cost of decommissioned power lithium batteries from recycling, logistics and transportation to appraisal and inspection is relatively high. Some people in the industry believe that the above-mentioned problems will become a puzzle when choosing new batteries or cascading batteries. 2. The battery lacks consistency. Since my country first launched a demonstration research project on the cascade application of power lithium batteries in 2014, the issue of battery consistency has always been a key challenge in the entire operation of the cascade application project. It is understood that the inconsistency of power lithium batteries in terms of capacity, internal resistance, and voltage is closely related to the principle of charge and discharge reaction of the battery itself. The authoritative expert of the Chinese Academy of Electric Power Science Lai Xiaokang once stated, “Even through the selection of retired batteries, when constructing a cascaded energy storage system, it is still impossible to avoid the occurrence of battery consistency and discrete variables in the operation of the system. situation. 'Three, the key technology is different. Some authoritative experts said,'Some people think that if the energy storage battery is left there, its technical standards are not so high. In fact, from a different perspective, the technical standards of some aspects of energy storage batteries are likely to be higher. 'Some people in the industry believe that in the future, new energy electric vehicles and energy storage end have different requirements for batteries. New energy electric vehicles tend to have high-efficiency energy density power lithium batteries, while energy storage end pays more attention to having a high cycle. Life-span batteries, so the key technologies of power lithium batteries and energy storage batteries will also be separated. In addition, there are still some doubts about whether there are safety risks and whether the reliability of the ternary power lithium battery is applied to the energy storage end in the future. Fourth, the value analysis is not uniform. At this stage, the pricing of decommissioned power lithium batteries in the market has a wide range, and there is no standard specification in the appraisal of the relative residual value of decommissioned batteries. Authoritative experts from the China Southern Power Research Institute believe that for the evaluation of a battery (or battery pack), the specific remaining storage capacity, health status, estimated number of remaining cycles, and full life cycle discharge data are left. It has a relatively direct impact on the market value of retired power lithium batteries. Nowadays, as to how to appraise the use value of decommissioned batteries, depots, users, recycling organizations, and energy storage power stations have not yet reached a consensus on the use value. Multi-faceted layout, forging ahead Although the power lithium battery is facing many objections and confusions in the use of echelon, the overall industry has never stopped moving forward in this direction, and has continued to make breakthroughs and growth. Many companies have gradually realized the importance of the cascade application of power lithium batteries for my country’s new energy vehicle industry, and have successively made arrangements at the cascade application level, moving forward amidst controversy.
