ABSTRACT The growing use of lithium iron phosphate (LFP) batteries has raised concerns about their environmental impact and recycling challenges, particularly the recovery Li. Here, we propose a new strategy for priority Li precise separation Fe P from spent LFP cathode materials via H 2 O‐based deep eutectic solvents (DESs). Through adjusting form metal complexes precipitation mode, above 99.95% can be dissolved in choline chloride‐anhydrous oxalic acid‐water (ChCl‐OA‐H O) DES, high efficiency 93.41% 97.40% accordingly are obtained. effects main parameters comprehensively investigated during leaching processes. mechanism pretreated is clarified rate‐controlling step heterogeneous dissolution reactions also identified. Results show that soluble phases 3 (PO 4 ) O formed after roasting pretreatment, Li(I) ions tend to C precipitates with 2− process so recovered preferentially purity 99.82%. After UV‐visible light irradiation, Fe(III) converted into Fe(II) ions, which react FeC by content, as Na PO ∙12H (99.98% purity). Additionally, plan used DES proposed performances still maintain stable three circles. method offers an approach simple process, efficiency, waste‐free DESs.

Abstract The pursuit of carbon‐neutral energy has intensified the interest in green hydrogen production from direct seawater electrolysis, given scarcity freshwater resources. While Ni‐based catalysts are known for their robust activity alkaline water oxidation, catalytic sites prone to rapid degradation chlorine‐rich environments seawater, leading limited operation time. Herein, we report a Ni(OH) 2 catalyst interfaced with laser‐ablated LiFePO 4 (Ni(OH) /L‐LFP), derived spent Li‐ion batteries (LIBs), as an effective and stable electrocatalyst oxidation. Our comprehensive analyses reveal that PO 3− species, formed around L‐LFP, effectively repels Cl − ions during mitigating corrosion. Simultaneously, interface between situ generated NiOOH Fe 3 (PO ) enhances OH adsorption electron transfer oxygen evolution reaction. This synergistic effect leads low overpotential 237 mV attain current density 10 mA cm −2 remarkable durability, only 3.3 % loss after 600 h at 100 seawater. findings present viable strategy repurposing LIBs into high‐performance sustainable contributing advancement technologies.

Cation separation under extreme pH is crucial for lithium recovery from spent batteries, but conventional polyamide membranes suffer pH-induced hydrolysis. Preparation of high performance nanofiltration with excellent pH-resistance remains a challenge. Here we synthesize membrane (1,4,7,10-Tetraazacyclododecane (TAD)−1,3,5-Tris(bromomethyl)benzene (TBMB) thin film composite (TFCMs)) pH-stability through interfacial quaternization reaction between TAD and TBMB. Due to the stability "C-N" bonds in TAD-TBMB TFCMs, its stable even after 70 days immersion concentrated acid (3 M H2SO4, HNO3, or HCl) base NaOH), which at least 15 times more than benchmark commercial membranes. The shows an overall (11.3 L m−2 h−1 bar−1 (LMHB), RCo2+: 97% 2 H2SO4) due size sieving intensified charge repulsion, outperforming many state-of-the-art Finally, TFCM during 30-days continuous H2SO4 leachate (2 ions: 6.2 g L−1) batteries. A highly pH-resistant was prepared by reaction, highest among analogous 70-days acid/base. Meanwhile, Li2CO3 purity 99.1% recovered
