Abstract Two-dimensional (2D) superlattices, formed by stacking sublattices of 2D materials, have emerged as a powerful platform for tailoring and enhancing material properties beyond their intrinsic characteristics. However, conventional synthesis methods are limited to pristine sublattices, posing significant practical challenge when it comes chemically modified sublattices. Here we report chemical method that overcomes this creating unique graphene superlattice, with monodisperse, nanometer-sized, square-shaped pores strategically doped elements at the pore edges. The resulting superlattice exhibits remarkable correlations between quantum phases both electron phonon levels, leading diverse functionalities, such electromagnetic shielding, energy harvesting, optoelectronics, thermoelectrics. Overall, our findings not only provide design principles synthesizing understanding functional superlattices but also expand enhanced functionality extensive application potential compared counterparts.

Abstract Aqueous Zn‐ion batteries (ZIBs) are a promising energy storage technology due to their intrinsic safety, eco‐friendliness, and cost‐effectiveness. However, aqueous electrolytes generally induce parasitic interfacial reactions (e.g., dendrite growth passivation) that degrade the Zn metal anode, shortening ZIBs lifespan. This study develops novel hydrated deep eutectic electrolyte (DEE), containing sulfolane (SL) Zn(ClO 4 ) 2 ·6H O, prevent water‐induced deterioration. The strong coordination between SL 2+ triggers effect, extending operating temperature window of DEE. unique water‐in‐DEE structure boosts ionic diffusion, promotes deposition, reduces water reactivity, as revealed by in‐depth simulations experiments. developed DEE suppresses formation, allowing Zn|DEE|Zn symmetrical cells cycle over thousands hours without short‐circuiting.

Abstract Rechargeable batteries with Li‐metal anodes and Ni‐rich LiNi x Mn y Co z O 2 ( + = 1, NMC) cathodes promise high‐energy‐density storage solutions. However, commercial carbonate‐based electrolytes (CBEs) induce deteriorative interfacial reactions to both NMC, leading Li dendrite formation NMC degradation. Moreover, CBEs are thermally unstable flammable, demonstrating severe safety risks. In this study, an ultrathin non‐flammable dual‐salt polymer electrolyte (DSPE) is proposed via lightweight polytetrafluoroethylene scaffold, poly(vinylidene fluoride‐ co ‐hexafluoropropylene) polymeric matrix, dual‐salt, adiponitrile/fluoroethylene carbonate functional plasticizers. The as‐obtained DSPE exhibits ultralow thickness of 20 µm, high room temperature ionic conductivity 0.45 mS cm −1 , a large electrochemical window (4.91 V versus Li/Li ). synergized plasticizers used fabricate stable interface layer on anode cathode. In‐depth experimental theoretical analyses have revealed the interfaces between anode/cathodes. As result, effectively prevents Li/DSPE/Li symmetric cell from short‐circuiting after 1200 h, indicating effective suppression dendrites. Li/DSPE/NMC delivers outstanding cyclic stability at C, maintaining capacity 112 mAh g over 1000 cycles.
