The accelerating electrification has sparked an explosion in lithium-ion batteries (LIBs) consumption. As the lifespan declines, the substantial LIBs will flow into the recycling market and promise to spawn a giant recycling system. Nonetheless, since the lack of unified guiding standard and nontraceability, the recycling of end-of-life LIBs has fallen into the dilemma of low recycling rate, poor recycling efficiency, and insignificant benefits.Herein, tapping into summarizing and analyzing the current status and challenges of recycling LIBs, this outlook provides insights for the future course of full lifecycle management of LIBs, proposing gradient utilization and recycling-target predesign strategy. Further, we acknowledge some recommendations for recycling waste LIBs and anticipate a collaborative effort to advance sustainable and reliable recycling routes.

“…At the same time, as LIBs are widely used as the energy storage unit and the most common power supply unit in new energy vehicles, mobile phones, and computers as well, a large amount of spent LIBs are wasted every year. If the material cannot be properly handled, the harmful substances inside can cause serious pollution to the environment. − Although there have been lots of research studies on the recycling of spent LIBs, − its development is still very slow due to the limited potential routes. Therefore, it is utmost necessary to find a reliable path for the practical application of spent LIBs.…”

The huge consumption of fossil fuels leads to excessive CO 2 emissions, and its reduction has become an urgent worldwide concern. The combination of renewable energies with battery energy storage, and carbon capture, utilization, and storage are well acknowledged as two major paths in achieving carbon neutrality. However, the former route faces the discard problem of a large amount of lithium-ion batteries (LIBs) due to their limited lifespan, while it is costly to obtain effective CO 2capturing materials to put the latter into implementation. Herein, for the first time, we propose a route to synthesize low-cost Li 4 SiO 4 as CO 2 sorbents from spent LIBs, verify the technical feasibility, and evaluate the CO 2 adsorption/desorption performance. The results show that Li 4 SiO 4 synthesized from the cathode with self-reduction by the anode graphite of LIBs has a superior CO 2 capacity and cyclic stability, which is constant at around 0.19 g/g under 15 vol % CO 2 after 80 cycles. Moreover, the cost of fabricating sorbents from LIBs is only 1/20−1/3 of the conventional methods. We think this work can not only promote the recycling of spent LIBs but also greatly reduce the cost of preparing Li 4 SiO 4 sorbents, and thus could be of great significance for the development of CO 2 adsorption. KEYWORDS: recycling of spent lithium-ion batteries, Li 4 SiO 4 sorbent, high-temperature CO 2 adsorption, adsorption and desorption

“…Lithium-ion batteries (LIBs) are widely applied in electric vehicles (EVs) and energy storage industries due to the advantages of high energy density, high output voltage, long life, etc. − A large number of lithium-ion batteries will be retired after long-term recycling. The recycling of spent cathode materials in spent lithium-ion batteries is extremely promising due to the lack of resources and rising prices of cathode materials for lithium-ion batteries. − Direct regeneration technology has been developed in the recycling of spent cathode materials because of its the advantages of short process, environmental friendly, low energy consumption, and high added value. − The traditional recovery method for extracting valuable elements from spent LiNi x Co y Mn 1– x – y O 2 (NCM) cathode material is limited by the difficulty of separation and purification and environmental pollution. The direct regeneration method can effectively avoid these problems. , The research on the direct regeneration technology of spent LiNi x Co y Mn 1– x – y O 2 cathode materials focuses on repairing the composition and structure defects of lithium-deficient cathode particles and maximizing the retention of the high added value of cathode particles .…”

The direct regeneration technology has been developed because of its short-range, high efficiency, and green characteristics. However, the existing direct regeneration method is hardly applied in collaborative reconstruction of the damaged crystal and particle of spent polycrystalline layered materials. The single-crystal regeneration with restructuring the morphology and crystal structure was herein achieved for the first time by low-temperature lithium supplementation followed with high-temperature molten salt conversion, which could effectively solve the structural defects of spent polycrystalline layered materials. We found that the realization of single-crystal regeneration with the molten salt process is attributable to that the original crystal growth of primary particles in the polycrystal transfer to the subsequent division along the grain boundary. At the test conditions of 25 °C and 2.8–4.3 V, the capacity retention capacity of the regenerated single-crystal materials reach 83.3% after 200 cycles at 1 C, which is much higher than 20.0% for conventional direct lithiation regeneration and 61.6% for low-temperature molten salt regeneration. Interestingly, the regenerated single-crystal NCM622 in the graphite full-cell test displays a capacity retention rate of 85.24% after 800 cycles at a rate of 1 C at 2.5–4.35 V. This work opens up a new way for the direct regeneration of spent polycrystalline layered cathode materials.
