MoS2 is considered a promising two-dimensional active channel material for future nanoelectronics. However, the development of facile, reliable, and controllable doping methodology still critical extending applicability MoS2. Here, we report surface charge transfer via thiol-based binding chemistry modulating electrical properties vacancy-containing (v-MoS2). Although vacancies present in 2D materials are generally regarded as undesirable components, show that can be systematically...
Abstract Spinel‐type LiNi 0.5 Mn 1.5 O 4 (LNMO) is one of the most promising 5 V‐class cathode materials for Li‐ion batteries that can achieve high energy density and low production costs. However, in liquid electrolyte cells, voltage causes continuous cell degradation through oxidative decomposition carbonate‐based electrolytes. In contrast, some solid‐state electrolytes have a wide electrochemical stability range withstand required potential. this work, thin‐film battery consisting an LNMO...
Abstract Here,nonprecious high‐entropy chalcogenide glasses (N‐HECGs) consisting of Co, Fe, Ni, Mo, W, and Te are demonstrated in a first demonstration acidic oxygen evolution reaction (OER). N‐HECGs electrocatalysts with high activity stability synthesized using hierarchical hybrid approach based on combination electrochemical deposition tellurization process. The as‐prepared CoFeNiMoWTe exhibit an amorphous, porous structure arrayed nanosheets abundant active sites the increased valence...
An octahedron-shaped Cu<sub>2</sub>O nanostructured electrode having {111} facets with high surface energy favourable for lithium ion transport revealed an enhanced conversion reaction mechanism reversible capacity and rate cycling performance.
While active materials based on germanium (Ge) are considered as a promising alternative anodic electrode due to their relatively high reversible capacity and excellent lithium-ion diffusivity, the quite unstable structural/electrochemical stability severe volume expansion or pulverization problems of Ge electrodes remain considerable challenge in lithium ion batteries (LIBs). Here, we present development embedded one-dimensional carbon nanostructures (Ge/CNs) synthesized by modified situ...
Abstract Practical implementations of solid polymer electrolytes (SPEs) in solid‐state lithium‐metal batteries (SSLMBs) are inhibited by the limited lithium‐ion (Li + ) transport and poor‐quality interface between SPEs both electrodes. exhibit lower ionic conductivity than other oxidized decomposed oxide‐based cathode materials high‐voltage windows. SSLMBs also long‐term destabilized parasitic side reactions at electrode–electrolyte interfaces Li dendrite formations. This study proposes a...
This work shows that hollow and microporous organic polymers (H-MOPs) are good templating materials for the synthesis of inorganic material–carbon nanocomposites. The precursor compound, (NH4)2MoS4, was incorporated into H-MOPs. Heat treatment under argon resulted in formation MoS2–carbon nanocomposites (MSC). According to microscopic analysis, MoS2 MSC has a layered structure with an elongated interlayer distance. showed high reversible discharge capacities up 802 mA h g−1 after 30 cycles...
