From first principles calculations, the lowest energy structures of bilayer MoSSe with different combination patterns (S-S, Se-Se, and S-Se bilayer) have been confirmed. The results demonstrate that the band gap of bilayer MoSSe can be tuned by the interlayer distance and the dipole moment. Larger interlayer distance increases the band gap, while l...

Motivated by the successful preparations and extraordinary properties of blue phosphorus (BP) and Janus MoSSe monolayer, we constructed the van der Waals (vdW) heterostructures composed of BP and Janus MoSSe monolayer denoted by BP-SMoSe and BP-SeMoS, respectively, investigated their electronic structures and the effects of external electric field...

Anti‐perovskites X3BA, as the electrically inverted derivatives of perovskites ABX3, have attracted tremendous attention for their good performances in multiple disciplines, especially in energy storage batteries. The Li/Na‐rich antiperovskite (LiRAP/NaRAP) solid‐state electrolytes (SSEs) typically show high ionic conductivities and high chemical/e...

Recently, a new family of anti‐perovskite Li2TMSO was discovered as promising cathode materials for Li‐ion batteries (LIBs) with superiorities in high specific capacity, low cost, and environmental friendliness. However, the applications of these anti‐perovskite materials meet severe challenges in the cyclability and rate performance. Herein, a cat...

Aqueous zinc‐ion batteries (AZIBs) stand out among many energy storage systems due to their many merits, and it's expected to become an alternative to the prevailing alkali metal ion batteries. Nevertheless, the cumbersome manufacturing process and the high cost of conventional separators make them unfavorable for large‐scale applications. Herein,...

Aqueous Zn‐ion batteries have emerged as promising candidates for large‐scale energy storage owing to their high safety and low cost. However, dendrite growth and side reactions compromise the stability of the Zn anode in practical applications. Here, a novel Zn anode featuring well‐designed crystal steps along the (002) facets, referred to as Step...

Inorganic solid-state electrolytes (ISSEs) have been extensively researched as the critical component in all-solid-state lithium-metal batteries (ASSLMBs). Many ISSEs exhibit high ionic conductivities up to 10-3 S cm-1. However, most of them suffer from poor interfacial compatibility with electrodes, especially lithium-metal anodes, limiting their...

All-solid-state lithium batteries (ASSLBs) have attracted much attention owing to their high safety and energy density compared to conventional organic electrolytes. However, the interfaces between solid-state electrolytes and electrodes retain some knotty problems regarding compatibility. Among the various SSEs investigated in recent years, halide...
