The TFSI⁻-based system (PPIL) exhibits smaller particle size, reduced crystallinity, and enhanced amorphous β-phase content, enabling improved ion mobility and a lower activation energy (69.0 kJ mol⁻¹). Solid-state NMR and Raman analyses reveal weaker Li⁺ coordination in PPIL, consistent with its higher ionic conductivity (1.22 × 10⁻³ S cm⁻¹). Interfacial characterizations show that PPIL promotes the formation of a stable, LiF/Li₃N-rich SEI.

While direct regeneration is considered sustainable, its widespread adoption is hindered by three critical challenges: 1) heterogeneous and unquantifiable lithium loss across waste streams, 2) abnormal particle growth during high-temperature restoration, and 3) limited economic returns arising from the low-value elements and complex process. Here, we report a universal and scalable “<i>x</i> → 0 → 1” normalization strategy. All spent Li_<i>x</i>FePO₄ is first reset to Li-free olivine FePO₄ (<i>x</i> → 0) via mechanochemical delithiation, eliminating batch-specific variability. Benefiting from the olivine FePO₄ with pre-existing Li⁺ diffusion channels and nonequilibrium kinetics, subsequent ultrafast heating resynthesis (UHR) restores stoichiometric lithium iron phosphate (0 → 1) in just 35 s, effectively suppressing particle coarsening while cutting energy/time consumption by &gt;99% compared to furnace sintering. This approach accommodates diverse degradation levels and their mixture, yielding regenerated lithium iron phosphate with consistent capacity, superior rate capability (84.3 mAh g⁻¹ at 10 C) and cycling stability (89.1% retention after 1000 cycles at 10 C), outperforming fresh commercial lithium iron phosphate (73.3 mAh g⁻¹, 66.6%). Beyond regeneration, flash upcycling to lithium manganese iron phosphate further enhances energy density to 549 Wh kg⁻¹. Techno-economic analysis confirms strong profitability (lithium iron phosphate: 4.86 $ kg⁻¹ cell, lithium manganese iron phosphate: 10.98 $ kg⁻¹ cell), low energy demand (6.56 MJ kg⁻¹ cell), and reduced emissions (2.95 kg CO₂-eq kg⁻¹ cell).

However, the photocatalytic activity of photocatalysts is generally limited due to multiple factors, such as insufficiency of photoelectrons, low adsorption capability of O₂ on the photocatalyst surface, and high thermodynamic barrier. To address these issues, herein we have designed an interesting kind of hollow HKUST-1@CuFePBA@CuS (HS@CuFe@CuS) heterojunction photocatalyst. HKUST-1 metal–organic frameworks (MOFs) with cubic morphology were first synthesized as the precursor. Next, Cu²⁺ ions were released from HKUST-1 for the growth of CuFe Prussian blue analogue (CuFePBA) nanosheets on the HKUST-1 surface and then CuS nanoparticles on the CuFePBA nanosheet surface, simultaneously creating a hollow structure in HKUST-1. It is demonstrated that the resultant photocatalysts exhibit remarkable photocatalytic activity for H₂O₂ synthesis. Particularly, the H₂O₂ yield rate reaches 927 μmol g⁻¹ h⁻¹ over the HS@CuFe@CuS-4, which is increased by 5.3, 10.3, and 5.2 times as compared with that over single HKUST-1, CuFePBA, and CuS, respectively. Experimental and theoretical studies outline several advantages of the hollow HS@CuFe@CuS heterostructures for boosting the photocatalytic H₂O₂ synthesis: 1) more photoelectrons available for O₂ photoreduction reactions due to the efficient photocarrier separation/transfer and unique hollow structure, 2) increased O₂ adsorption on the active sites, and 3) a decrease in the Gibbs free energies for O₂ photoreduction reactions.

This hierarchical architecture enables synergistic enhancement of charge separation through built-in electric field effects, achieving the most suppression of electron–hole recombination compared to pristine ZnIn₂S₄.

Notably, an apparent quantum efficiency of 11.4% was achieved at 420 nm monochromatic light, accompanied by remarkable stability over long-term cyclic tests. Combined X-ray photoelectron spectroscopy analysis and density functional theory calculations reveal dual enhancement mechanisms: the redistribution of interface charges helps to increase the density of photogenerated electrons and photogenerated holes as well as facilitate efficient carrier migration, while the p-n junction's band alignment promotes redox reaction kinetics.

Herein, short-chain ligand tridecylamine (TDA) is introduced as a surface passivation strategy to synthesize high-performance sky-blue CsPbBr₃ QDs via size engineering, which show a stable photoluminescence (PL) intensity with a higher PL quantum yield (PLQY).
