In this work, the effects of varying crystal water content on the structure and electrochemical performance of MnHCF materials were systematically investigated. The results indicated that rhombohedral MnHCF with trace crystal water (R-MnHCF-W) exhibits superior structural stability compared to monoclinic MnHCF (M-MnHCF) with abundant crystal water and anhydrous MnHCF (R-MnHCF-0).

Although LiNO₃ effectively optimizes interfacial chemistry as an electrolyte additive, its application remains hampered by limited carbonate-electrolyte solubility and self-depleting behavior during extended cycling. This study presents an innovative interfacial engineering strategy through the strategic incorporation of LiNO₃-impregnated hollow mesoporous silica composites (HMS@LiNO₃) onto separator surfaces to achieve dual-interface modulation. Capitalizing on the strong adsorption capability of HMS within the high-dielectric ethylene carbonate, a nitrate-rich solvation structure is lastingly established at the anode interface. The configuration facilitates the formation of a Li₃N-enriched solid electrolyte interphase with superior ionic conductivity, effectively enhancing lithium deposition kinetics while inhibiting dendritic growth. Concurrently, the cathode interface benefits from a controlled nitrate-lean solvation sheath that preferentially undergoes oxidative decomposition, generating a robust protective layer to mitigate electrolyte decomposition under 4.5 V operation. As a result, the lifetime in Li plating/stripping exceeds 1800 h and the average Coulombic efficiency is as high as 98.25 % over 350 cycles.

An exact multi-physics simulation confirmed that DL could be directly excited by the interfacial electric field in liquid-solid contact without any pretreatment. A relevant strategy of semi-embedding luminescent particles in ultra-thin polymer film was proposed to ensure sufficient liquid-solid contact to transfer the interfacial charge and maximize the direct excitation of luminescent particles by the interfacial electric field.
