Abstract Dendrite growth of alkali metal anodes limited their lifetime for charge/discharge cycling. Here, we report near-perfect lithium, sodium, and potassium metals achieved by electrochemical polishing, which removes microscopic defects creates ultra-smooth ultra-thin solid-electrolyte interphase layers at surfaces providing a homogeneous environment. Precise characterizations AFM force probing with corroborative in-depth XPS profile analysis reveal that the can be designed to have...
Abstract Conventional lithium‐ion batteries have approached their capacity and energy density limits. Use of lithium metal anode can enable high‐energy batteries. However, the safety hazards dendrite formation associated with require safe electrolytes to replace flammable liquid ones. In recent years, solid‐state attracted tremendous attention. Among them, composite polymer (CPEs) different constitutions unique advantages low interfacial resistance, high ionic conductivity, flexible...
Sodium metal anodes are poor due to the reversibility of Na plating/stripping, which hinders their practical applications. A strategy form a sodiophilic Au-Na alloy interphase on Cu current collector, involving sputtered Au thin layer, is shown enable efficient plating/stripping for certain period time. Herein, electrochemical behaviors plating different substrates explored, and it revealed that can be achieved universally by in situ formation M-Na (M = Au, Sn, Sb) alloys during prior bulk...
Lithium metal anodes suffer from poor cycling stability and potential safety hazards. To alleviate these problems, Li thin-film prepared on current collectors (CCs) Li-free types of that involve direct plating CCs have received increasing attention.

Conventional organic batteries suffer from rapid capacity fading. Organic compounds are inclined to dissolve in the electrolyte and limit long-term cycling performance of lithium–organic batteries. Carbon skeletons show efficacy confining active materials cathodes. In this study, we investigate electrochemical aqueous zinc-ion with binder-free composite cathodes consisting carbon nanotubes (CNTs) naphthoquinone (NQ)-based organics. The quinones trapped nanoporous structure CNT framework,...
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...
Vertical few-layer graphene (FLG) sheets have been fabricated by using microwave-plasma-enhanced chemical vapour deposition. Their shape was manipulated through adjusting the growth time and hydrocarbon gas ratio. The mechanism during different stages is discussed. field emission characteristics for FLG shapes were tested found to be strongly influenced tip shape, height amorphous carbon content. optimal of vertical had fewer layers, sharp corners, large free carbon. best properties with...
Organosulfides are promising candidates as cathode materials for the development of electric vehicles and energy storage systems due to their low-cost high capacity properties. However, they generally suffer from slow kinetics because large rearrangement S-S bonds structural degradation upon cycling in batteries.

Benefiting from controlled fabrication with real-time observation, ZrC has smooth surface tip radius of curvature smaller than 20 nm length greater 2 μm. Due to low work function well-controlled morphology, emitter, positioned high-vacuum chamber, able...
