Abstract Direct regeneration of spent lithium batteries (LIBs) cathodes has emerged as a transformative regimen to address the urgent need for sustainable recycling methods and mitigate critical shortage metal resources driven by escalating LIB demand. Unlike conventional focused on extraction separation, direct restores functionality cathode in situ, streamlining process enhancing efficiency. Effective necessitates comprehensive understanding failure mechanisms pretreatment processes. Critical strategies include reducing (Li) migration barrier enable complete reinsertion into structure minimizing Li‐transition anti‐site defects reconstruct lattice. This review summarizes advancements mechanisms, techniques, cathode, emphasizing principles innovations regeneration. By evaluating advantages limitations current approaches, opportunities are identified innovation overcome existing challenges. Future research priorities proposed advance technologies, fostering more efficient systems.

Abstract The practical implementation of Li metal anode has long been hindered by the significant challenges notorious dendritic growth and severe interphase instability during repeated cycling. Herein, a highly lithiophilic NiSe‐modified host rationally constructed to stabilize facile mechanical rolling strategy. in situ configurated high‐flux 2 Se‐enriched layer can facilitate fast interfacial charge transfer, high plating/stripping reversibility homogeneous nucleation/growth. Consequently, achieved modified demonstrates ultrahigh rate capability (10 mA cm −2 ) ultralong‐term cycling stability (6600 cycles) with dendrite‐free deposition. Li|LiFePO 4 (LFP) cell exhibits an extraordinarily lifespan over 500 cycles ultra‐low decay only ≈0.0092% per cycle at 1 C. Furthermore, 4.5 V high‐voltage Li|LiCoO pouch areal capacity (≈1.9 mAh still reveals impressively prolonged cyclability 200 even under harsh test condition low negative‐to‐positive‐capacity (N/P) ratio ≈3.4 lean electrolyte ≈5.5 µL −1 . This work provides scalable strategy toward stable for reliable usage.

The initial irreversible capacity loss during the first charging process largely reduces affordable energy and power density of sodium storage devices, developing advanced materials is efficient way to solve this problem, which fraught with challenges. Herein, inspired by theoretical calculations high-entropy concept, a series fewer layers metal-organic frameworks (FLHE-MOFs) are successfully fabricated, delivering an ultrahigh Coulombic efficiency (ICE) 86.1% excellent cycling performance, far more than that other electrode (generally <70%). Greatly, behavior high-, medium-, low-entropy MOFs clarified

Developing an effective recycling process for reclaiming valuable metals from lithium-ion batteries is urgent issue owing to increasing battery waste electric vehicles. In this study, we developed a leaching method that enables the direct separation of lithium other critical metals, namely, nickel and cobalt, using two-phase system consists deep eutectic solvent (DES) water. The DES consisting 4,4,4-trifluoro-1-phenyl-1,3-butadione tri-n-octylphosphine oxide showed highest performance when combined with Several operational parameters, such as aqueous fraction, solid-liquid ratio, reaction time, operation temperature, were evaluated. optimum results in obtained 1:1 DES-water ratio 10 g/L reacted at 80 °C 24 h. An in-situ stripping phenomenon was observed, revealing transferred phase phase. application black mass leaching, significantly enhanced Co, Ni, Mn extraction into thus plays important role separating metals. efficiency reached 99% within

In an era so focused on sustainability, it is important to improve chemical processes by developing and using more environmentally friendly solvents technologies. Deep eutectic (DES) have proven be a promising replacement for conventional solvents. recent years, new type of DES has emerged that responds various stimuli. These responsive (RDES) may offer all the advantages while allowing recycling reuse As such, RDES can further contribute greener future. This review provides overview diverse types RDES, their switching mechanisms application in several fields. Lastly, offers critical perspective current shortcomings prospects.
