“…Yan et al introduced an advanced oxidation process (S 2 O 8 2– : sulfate radical generator, and Fe 2+ : catalyst) into the ultrasonic-assisted separation process of cathode materials and Al foils, which can achieve efficient degradation of PVDF binder, avoiding reactions between chemical reagents, electrode materials, and metal foils, and facilitate the in situ recovery of cathode materials and Al foil. Huang et al quantitatively analyzed the influence of ultrasonic treatment and sulfate radicals (from K 2 S 2 O 8 ) on the separation efficiency of SLIB cathode active materials and Al foil through the statistical significance analysis and response surface methodology based on central composite design. They found that there is a coupling effect between persulfate salts and the ultrasound.…”

The recycling of spent lithium-ion batteries can not only reduce the potential harm caused by solid waste piles to the local environment but also provide raw materials for manufacturing new batteries. Power ultrasound is one of the effective means to enhance the resourceful recycling of spent lithium-ion batteries, and the unique physical and chemical effects are the main mechanisms that lead to the enhancement. A large number of studies reported the recycling and utilization of cathode materials from spent lithium-ion batteries with the assistance of ultrasound. In this paper, first, we discuss the pathway of ultrasonic enhancement of the resource-based recycling of spent lithium-ion batteries regarding the introduction of ultrasonic cavitation theories; second, we systematically review the research of ultrasonic applications in the separation of metal collectors from, the recovery of, and the regeneration of cathode materials of spent lithium-ion batteries; finally, shortcomings of the ultrasound-assisted technology in industrial applications are discussed, and prospects of industrial ultrasonic applications in the resource recycling and utilization of spent lithium-ion batteries are proposed.

“…Some researchers are turning recycled battery materials into valuable products (various sulfates, lithium carbonate, or other value-added products). Some of these valuable products can be used as raw materials for battery production, while some are made into other products (Huang et al, 2021). However, the best destination for the metal recovered from LIBs is still made into LIBs material, forming closed-loop recycling.…”

Lithium-ion batteries (LIBs) account for the majority of energy storage devices due to their long service life, high energy density, environmentally friendly, and other characteristics. Although the cathode materials of LIB led by LiFePO4 (LFP), LiCoO2 (LCO), and LiNixCoyMn1-x-yO2 (NCM) occupy the majority of the market share at present, the demand of LiMn2O4 (LMO) cathode battery is also increasing year by year in recent years. With the rising price of various raw materials of LIBs and the need of environmental protection, the efficient recycling of spent LIBs has become a hot research topic. At present, the recycling of spent LIBs mainly focuses on LFP, LCO, and NCM batteries. However, with the continuous improvement of people’s safety of LIBs, LiMnxFe1-xPO4 (LMFP) batteries show better potential, which also improves the recycling value of LMO batteries. Therefore, this paper reviews current methods of spent LMO recovery, focusing on the characteristics of the recovery and separation process, which can serve as a reference for subsequent research on LMO recovery, increasing environmentally friendly recovery routes. Finally, the future development direction of LIBs recycling is prospected. Overall, this review is helpful to understand the current progress of LMO battery recycling.

“…Most of the waste treatment models in the literature have focused only on the applications of a certain process; for example, the suggestion in [8], in which the life cycle performance evaluation for dismantled manufacturing is underexamined because the complex design of such a system might lead to higher costs, making this strategy economically unsustainable. Research regarding the recycling of spent lithium-ion batteries has provided meaningful references for this study [9]. Despite sustainability evaluation being a research hotspot, according to our best knowledge, no one has examined the environmental performance of life cycle dismantling processes in an integrated manufacturing method.…”

With the increase in battery usage and the decommissioning of waste power batteries (WPBs), WPB treatment has become increasingly important. However, there is little knowledge of systems and norms regarding the performance of WPB dismantling treatments, although such facilities and factories are being built across the globe. In this paper, environmental performance is investigated quantitively using life cycle assessment (LCA) methodology for a dismantled WPB manufacturing process in Tongliao city of Inner Mongolia Province, China. The functional unit was selected to be one metric ton of processed WPB, and the average data of 2021 were used. The results indicated that WPB dismantling treatments are generally sustainable in their environmental impacts, because the life cycle environmental effects can be neutralized by the substitution of virgin products with recycled counterparts. Of all the processes of dismantlement, Crude Lead Making, Refining, and Preliminary Desulfurization, were the top three contributors to the total environmental burden. The results of the sensitivity analysis showed that increasing photovoltaic power, wind power, and natural gas usage may significantly reduce the burden on the environment. On the basis of our findings, some suggestions are put forward for a policy to promote environmental green growth of WPB treatment. Although this paper is aimed at the power lead–acid battery, the research method is also of significance for the power lithium-ion battery, and we will conduct relevant research on the disassembly process of the power lithium-ion battery in the future.
