However, the sluggish defect-repair kinetics in traditional solid-phase routes remains mechanistically unclear, limiting the practical deployment of this technology. Here, theoretical calculations reveal that the phonon localization in defect-rich S-LFP is the essential factor responsible for the sluggish defect-repair kinetics. Localized phonons retard thermal diffusion, hindering the energy available to overcome defect repair barriers, and concurrently intensify electron-phonon coupling that suppresses the electron migration necessary for the reduction of Fe(III). Guided by this insight, we employ electric/thermal coupling field strategy to repair the S-LFP cathode. Carriers driven by the electric field transfer energy to phonons through electron-phonon scattering, which promotes energy redistribution across disparate phonon modes, collectively enhancing phonon delocalization. As a result, Li-Fe antisites (Fe<sub>Li</sub>) were repaired within 5 s at 700°C, and the complete structural repair and lithiation are achieved within 60 s. Experimental results indicate that the regenerated cathode delivers a discharge specific capacity of 151.2 mAh g<sup>−1</sup> at 0.1C, and exhibits a capacity retention of 84.3% after 1100 cycles at 1 C.

Here, oxygen‐coordinated Ni single atoms on the TiO <jats:sub>2</jats:sub> (001) nanosheet arrays regulate both steps. Isopropanol‐probe and in situ glycerol spectra support Ni‐promoted dissociative adsorption through the secondary hydroxyl group. Radical spectroscopy and interfacial kinetics support subsequent oxidation through glycerol‐derived alkoxy species, accompanied by a 15–20‐fold acceleration of glycerol‐coupled hole transfer and suppressed oxygen evolution. Product‐based glycerol isotope effects supported the kinetic involvement of central C–H cleavage in DHA formation, while calculations showed that Ni coordination increased the energetic preference for C–H over C–C cleavage from 0.05 to 0.38 eV. Operando spectroscopy and weaker DHA adsorption support retention of the three‐carbon skeleton and product release. Under charge‐normalized conditions, the Ni single‐atom photoanode achieved a DHA Faradaic efficiency of approximately 66.6%, compared with 22.2% for unmodified TiO <jats:sub>2</jats:sub> and 16.4% for the NiO <jats:sub>x</jats:sub> control.
