Transition-metal oxides (TMOs) are promising anode materials for high-performance lithium-ion batteries (LIBs) because of their abundant reserves and high theoretical capacity. However, the poor conductivity, unstable solid electrolyte interface (SEI) film, cycling stability still limit practical applications. As a novel kind material, high-entropy oxide (HEO) is single-phase crystal structure composed multiple metal elements, demonstrating huge potential energy storage applications due to...

Benefiting from synergistic effect strong...
Abstract Regarding different kinds of alkali metal ion batteries such as lithium‐ion battery (LIB), sodium‐ion (NIB), and potassium‐ion (KIB), since the diameters properties these ions are different, there few materials that adaptable simultaneously anode for batteries. To achieve versatile compatibility material, its chemical component spatial configuration need to be predesigned possessing abundant storage sites efficient diffusion paths. Here, a well‐designed 3D material...
Abstract The high activity of nano‐sized metal particles (NMPs) makes it easy to appear uncontrolled aggregation, which seriously affects Li/Na storage in electrode materials. Introducing adaptive substrates with proper affinity NMPs is an effective strategy that optimizes the stability and capacity related electrodes.

The synthetic robustness this strategy was further demonstrated by the late-stage functionalization natural products their ligation other drugs via...
Abstract Solid‐state polymer electrolytes (SSPEs) have attracted considerable attention for use in all‐solid‐state lithium‐metal batteries (ASSLMBs). However, their low Li‐ion conductivity, small transference number, and poor interfacial compatibility hinder practical application, which may be associated with the uncoordinated interactions between key components SSPEs including polymers, lithium salts, nanofillers. In this study, fluoride graphdiyne (FGDY) is used as a nanofiller to enhance...

Such materials are peer reviewed may re-organized online delivery, but...
The importance of conical intersections (CIs) in electronically nonadiabatic processes is well known, but their influence on adiabatic dynamics has been underestimated. Here, through combined experimental and theoretical studies, we show that CIs induce a barrier regulate conversion from precursor metastable intermediate (CI-R) to deep one. This results bond-selective activation, influencing the markedly C(1D) + HD reaction. Theory validated by experiment; quantum calculations highly...

Topochemical reactions are a promising method to obtain crystalline polymeric materials with distance-determined regio- or stereoselectivity. It has been concluded on an empirical basis that the closest intermolecular C⋯C distance in crystals of alkynes, d(C⋯C)min, should reach threshold ∼3 Å for bonding occur at room temperature.
