Although various SEI-related strategies have been developed, the Li⁺ transport properties and uniform Li deposition still require substantial improvement for fast-charging applications. Herein, we introduce a dielectric, single-ion-conductive artificial SEI (DS-SEI) composed of lithiated Nafion and BaTiO₃ (BTO) nanoceramics to address these issues. The lithiated Nafion stabilizes the Li anode with its elastic F-rich components and facilitates fast, single Li⁺ conduction through its anion-anchored structure. The high-dielectric BTO dynamically homogenizes the electric field (E-field) to promote uniform Li deposition, synergistically enhancing intrinsic single Li⁺ conductivity and Li⁺ desolvation/diffusion kinetics, thereby enabling fast charging of the Li anode. Consequently, the DS-SEI protected Li anode can cycle over 6800 h in a Li||Li cell at 10 mA cm⁻²/5 mAh cm⁻², over 400 cycles in a 2.75 mAh cm⁻² Li||LiFePO₄ cell at 1C, with 83.0 % capacity retention at 6C (16.5 mA cm⁻²), and maintain stable cycling in a 5.62 mAh cm⁻² Li||Li₆PS₅Cl|| LiNi_0.8Co_0.1Mn_0.1O₂ all solid-state cell.

However, weak non-metal interbinding, susceptibility to photocorrosion, and high photogenerated carrier recombination rates hinder their practical applications. Herein, for the first time, we report a novel non-metal elementary substance heterojunction Se/S based on interfacial bonding engineering strategy. Atomic-level tight coupling of sulfonyl-rich sulfur quantum dots (SQDs) with selenium microtube arrays (Se-MTAs) enhances the structural stability of Se/S and introduces crucial Se–S heterointerfacial bonds, which not only endow Se/S with robust internal electronic interactions, but also provide high-speed channels for charge separation via unique bridging. Consequently, Se/S achieves optimal photocurrent density of 3.91 mA cm⁻² at 0 V_RHE, accompanied by long-term stability over 24 h. It is the highest value reported to date for Se-based photocathodes without co-catalyst and outperforms most metal-selenide-based photoelectrodes.

However, developing cathode materials that offer both high energy density and durability for Zn²⁺ ions storage remains challenging. Manganese (Mn) oxide-based cathodes have been developed for AZIBs due to their high discharge voltage and desirable capacity, but face challenges like poor conductivity, slow reaction kinetics, and dissolution during cycling. Doping, morphology/structure design, and protective layers are effective for enhancing the structure, conductivity, and electronic properties of Mn-based oxides. A synthetic strategy combining these methods for Mn₃O₄ cathodes is proposed for AZIBs. K⁺ ions doping in Mn₃O₄ (K-Mn₃O₄) can regulate local electronic structure, induce oxygen vacancies, improve conductivity, and provide more active sites for Zn²⁺ ions diffusion. Additionally, K-Mn₃O₄ nanochain (K-Mn₃O₄-NCs), with a unique chain-like nanostructure (NCs) and high aspect ratio, synthesized via Mn²⁺ ions chelation with nitrilotriacetic acid (NTA) and calcination, show reduced interparticle contact resistance, shorter Zn²⁺ ions diffusion length, and faster reaction kinetics. Meanwhile, the in-situ polymerized polyaniline (PANI) layer on K-Mn₃O₄-NCs shields against corrosion (K-Mn₃O₄-NCs@PANI), connects 1D K-Mn₃O₄-NCs into a continuous conductive network, suppresses volume expansion, and improves stability. Electrochemical analysis shows that K-Mn₃O₄-NCs@PANI exhibits higher stability and faster reaction kinetics due to a reduced bandgap, increased oxygen defects, and less coulombic repulsion between Zn²⁺ ions and Mn oxide hosts.

In this study, a copper powder graphdiyne (Cu-GDY) composite catalyst with ohmic angle contact was synthesized by coupling copper foil with <em>hexa</em>-hexylbenzene. Incorporating Cu-GDY into CoGdO₃ results in an interleaved band structure forming a type II heterojunction at the contact interface. This configuration overcomes the issue of the unfavorable conduction band position of CoGdO₃, thereby promoting charge transfer. The internal electric field created by the Fermi level difference between Cu-GDY and CoGdO₃, increase in REDOX capacity is the main reason for the increase of carrier separation rate. In addition, the plasmonic properties of copper expand the active reaction sites and promote the hydrogen evolution reaction. The composite catalyst exhibits b a hydrogen production rate that is 10.5 times higher than that of the individual catalysts.
