A series of single atom supported on Ti<sub>2</sub>CO<sub>2</sub> and Mo<sub>2</sub>CO<sub>2</sub> MXenes were systematically explored as efficient electrocatalysts for electro-catalytic N<sub>2</sub> reduction. We demonstrate that Ru Mo atoms anchored are highly activity.
Developing highly active, non-noble-metal H2 -evolution catalysts is appealing yet still remains a great challenge in the field of electrocatalytic and photocatalytic production. In this work, high quality transition-metal carbonitrides M3 CN (MXene) are investigated using well-defined density functional theory (DFT) calculations. The structural configurations, H-adsorption free energy (ΔGH ) charge transfer for bare, surface-terminated (TM)-modified CNO2 systematically studied. calculated...
The development of anode materials with good stability, high capacity, and excellent electrical conductivity is an important challenge for high-performance Li-ion batteries. Herein, the feasibility BeB2 MgB2 monolayers as batteries has been theoretically investigated. simulation results reveal that maintain throughout lithiation process. Meanwhile, Li–BeB2 Li–MgB2 systems exhibit small changes in lattice (−1.66 1.75%) during lithiation/delithiation process showing cycle stability. energy...
The poor compatibility of carbonate-based electrolytes with lithium metal anodes results in unstable solid electrolyte interphase, leading to dendrite formation, low Coulombic efficiency, and short cycle life. To address this issue, we propose a novel fluorinated that leverages bis(fluorosulfonyl)imide (LiFSI), along solvents. An extremely concentration nitrate exerts substantial impact on the Li ion solvation structure, inducing an anions-rich inorganic-rich interphase layer mainly composed...
As emerging cutting-edge energy storage technologies, aqueous zinc-ion batteries (AZIBs) have garnered extensive research attention for its high safety, low cost, abundant raw materials, and, eco-friendliness. Nevertheless, the commercialization of AZIBs is mainly limited by insufficient development cathode materials. Among potential candidates, MXene-based materials stand out as a promising option their unique combination hydrophilicity and conductivity. However, Zn2+ kinetics, structural...
We designed MoS2/M2CS2 (M = Ti, V) heterostructures and investigated their electrochemical performances to evaluate possibility serve as anode materials for metal (Li/Na/K/Mg)-ion batteries (LIBs/NIBs/KIBs/MIBs) by the first-principles method. The results show that two are stable exhibit metallic properties before or after adsorption of ions. low diffusion barriers (below 0.4 eV) indicate have excellent rate four batteries. theoretical capacities NIBs (about 400 mAh/g) LIBs 320 all much...
Abstract Low Coulombic efficiency and significant capacity decay resulting from an unstable solid electrolyte interphase (SEI) dendritic growth pose challenges to the practical application of lithium‐metal batteries. In this study, a highly efficient protection layer induced by octaphenylsilsesquioxane (OPS) with LiFSI salt is investigated. The OPS exhibits strong adsorption energy lithium, its multi‐site gradient ability enables simultaneous capture 8 Li + uniform regulation ion flux....
Despite the significant advances achieved in recent years, development of efficient electrolyte additives to mitigate performance degradation during long-term cycling high-energy density lithium||nickel-rich (Li||Ni-rich) batteries remains a challenge. To achieve rational design electrolytes and avoid unnecessary waste resources due trial error, it is crucial have comprehensive understanding underlying mechanism key components, including salts, solvents, additives. Herein, we present...
Compared with nanosilicon, microsilicon high capacity is the best candidate for high-energy-density lithium-ion batteries due to its lower cost and fewer interfacial side reactions. However, particle cracking even pulverization caused by huge volume expansion low ionic conductivity of seriously hinder large-scale application. Here, we prepared a rigid-flexible coupled modification layer flakes (Si) using polydopamine (PDA) as bridging agent MXene (Ti3C2Tx) buffer layer. The hydrogen bonds...
