Insights into the Mechanisms Behind Structural Repair of Spent Layered Cathode Materials for Lithium‐Ion Batteries
Abstract Structural repair is a vital step in the direct recycling of spent LiNi x Co y Mn z O 2 lithium‐ion batteries, yet its underlying mechanisms remain insufficiently clear. Herein, the thermal solid‐state structural repair of spent LiNi 0.6 Co 0.2 Mn 0.2 O 2 (NCM622) layered cathode material is systematically investigated. Through multiscale techniques combining XRD, XAS, and 6 Li solid‐state NMR, we identify the structural degradation in spent NCM622 and monitor both long‐ and short‐range structural evolution during repair. Our findings reveal that degradation predominantly occurs through Ni migration into Li octahedral sites, while Co and Mn demonstrate relatively lower occupancies in the Li layer. Such occupancies are primarily responsible for structural disorder and cubic‐symmetry domain formation within the spent material. The repair process is demonstrated to involve re‐lithiation, oxygen capture, increased transition metal (TM) oxidation states, and the migration of TM ions from the Li layer back to the TM layer, followed by cation diffusion. Both temperature and lithium compensation ratio are identified as critical factors promoting these processes. Capacity recovery studies show a strong correlation between reduced TM occupancy in the Li layer and improved electrochemical performances. These insights allow us to move beyond conventional phase‐transition perspectives, offering an atomic‐level understanding of structural degradation and repair mechanisms in spent layered cathode materials.

Self‐Assembly of a Customizable Library of Nickel Trifluoromethylation Catalysts via Selective C─F and C─O Bond Cleavage
Abstract Using a combination of metal‐promoted reactivity, in situ covalent bond modification, and hydrogen bonding‐promoted fluorine labilization, a unified approach was developed to self‐assemble a library of customizable ligand architectures directly at the nickel center via selective cleavage of C─F or C─O bonds and the formation of C─C or C─N bonds. As a result, a structurally diverse set of nickelacarbatrane and pincer complexes was obtained, including unsymmetrical and mixed‐heterocyclic atranes and trifluoromethylated pincers that cannot be accessed by conventional organic synthetic methods or require multiple steps and a tedious and low‐yielding separation. This suggests a possibility of a spontaneous generation of high‐complexity structures from a commonly used metal precursor and simple N‐heterocycle building blocks, despite commonly believed innocence of the C─F bonds, which may also generate catalytically active species.

Visible‐Light‐Controlled Lysine‐Selective Crosslinking Decodes Protein Complexes and Dynamic Interactomes in Live Cells
Abstract Crosslinking strategies have emerged as an attractive technology for deciphering protein complexes and protein–protein interactions (PPIs). However, commonly used crosslinking strategies present significant challenges for the precise analysis of protein complexes and dynamic PPIs in native biological environments. Here, we report the development of the first visible‐light‐inducible lysine‐specific homobifunctional photo‐crosslinkers and introduce V isible‐light‐controlled L ysine‐selective crosslinking (VL‐XL) strategy for in‐depth analysis of protein complexes and profiling dynamic interactomes in live cells. By synergistically integrating the advantages of temporal control, high biocompatibility, and lysine selectivity, the VL‐XL strategy not only provides an effective solution for protein complexes studies—achieving residue‐specific crosslinked peptides, delivering high‐confidence data and streamlined mass spectrometry (MS) data analysis—but also reveals dynamic interactomes in various scenarios. The VL‐XL strategy successfully profiles the time‐resolved, epidermal growth factor (EGF)‐stimulated epidermal growth factor receptor (EGFR) interactome, providing valuable insights into regulatory mechanisms of EGFR signaling. More importantly, the VL‐XL strategy effectively unveils molecular glue degrader‐induced E3 ligase interactome, leading to discovery of neo‐substrates such as Sestrin‐2 (SESN2) and opening an innovative avenue for identifying novel targets for degradation. Overall, the VL‐XL strategy provides a robust chemical tool, inspiring innovative solutions to address unresolved questions in multiple fields.
