Abstract The kinetics and storage‐capacity of NiCoMg‐ternary layered double hydroxide (NiCoMg‐LDH) are successfully boosted by valence engineering. As the cathode for aqueous magnesium‐ion batteries (AMIBs), assembled NiCoMg‐LDH//active carbon (AC) delivers a high specific discharge capacity (121.0 mAh·g −1 at 0.2 A·g ), long‐term cycling stability (85% retention after 2000 cycles 1.0 ) an excellent performance −30 °C. Moreover, NiCoMg‐LDH//perylenediimide (PTCDI) is assembled, achieving stability. X‐ray absorption spectra (XAS)/X‐ray photoelectron spectroscopy (XPS) analyses Density functional theory (DFT) calculations disclose that electrons redistributed due to 3 d orbital overlap Co/Ni atoms in NiCoMg‐LDH, which obviously reduces states atoms, enhances Mg─O bond strength degree hybridization O 2 p orbitals. Hence, electronic conductivity significantly enhanced electrostatic repulsion between Mg 2+ host layers greatly reduced, giving rise improved diffusion . Furthermore, situ Raman/X‐ray diffraction (XRD) ex XPS reveal corresponding energy‐storage mechanism. This paper not only demonstrates feasibility LDHs as AMIBs, but also offers new modification method engineering high‐performance electrode materials.

Abstract Uncontrolled dendrite growth, hydrogen evolution and corrosion challenges associated with zinc (Zn) anodes significantly restrict the practical application of batteries. Herein, a liquid metal gallium (Ga) interface is in situ formed on carbon paper (CP) by electrochemical co‐deposition to construct dendrite‐free Zn‐Ga@CP composite electrode which can regulate transport chemistry Zn deposition at electrode/electrolyte interface. Notably, concurrent reduction 2+ Ga 3+ results formation self‐supporting 3D interpenetrating structure Ga. Compared foil electrodes, highly conductive layer lowers nucleation energy barrier promotes homogeneity electric field ion flux, induces uniform Zn. In addition, low chemical activity prevents high rate reaction parasitic reactions. As result, symmetric cell delivers stable cycling >350 h discharge depth 23.3% ultra‐low voltage hysteresis. Moreover, coin‐type pouch‐type full cells exhibit excellent durability good mechanical stability. This work provides novel regulation strategy for achieving high‐performance anode
