Abstract Rechargeable lithium batteries using 5 V positive electrode materials can deliver considerably higher energy density as compared to state-of-the-art lithium-ion batteries. However, their development remains plagued by the lack of electrolytes with concurrent anodic stability and Li metal compatibility. Here we report a new electrolyte based on dimethyl 2,5-dioxahexanedioate solvent for V-class Benefiting from particular chemical structure, weak interaction cation resultant peculiar...
We have rationally synthesized and optimized catalytic nanoparticles consisting of a gold core, covered by palladium shell, onto which platinum clusters are deposited (Au@Pd@Pt NPs). The amount Pt Pd used is extremely small, yet they show unusually high activity for electrooxidation formic acid. structure has only 2 atomic layers half-monolayer equivalent (θPt ≈ 0.5) but further increase in the loading or will actually reduce activity, inferring that synergistic effect exists between three...

Their morphological, optical, material properties characterized; their potential use as a versatile signal amplifier was investigated experimentally using pyridine probe molecule theoretically by the three-dimensional finite-difference time-domain (3D-FDTD) method. We show that thin 2 nm...

Sodium metal anodes combine low redox potential (-2.71 V versus SHE) and high theoretical capacity (1165 mAh g-1), becoming a promising anode material for sodium-ion batteries. Due to the infinite volume change, unstable SEI films, Na dendrite growth, it is arduous achieve long lifespan. Herein, an oxygen-doped carbon foam (OCF) derived from starch reported. Heteroatom doping can significantly reduce nucleation resistance of sodium metal; combined with its rich pore structure large specific...

However, shell SiO Al can easily be dissolved in alkaline media, which limits applications SHINERS systems. Besides that, synthesis NPs further simplified replaced by other that are more amenable for mass production. In an attempt make...
