One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that

Molten Salt Electrolyte for Enhanced Low‐Temperature Sodium Liquid Metal Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces the application of a low‐temperature, high‐conductivity, solvent‐free Na/KFSI molten salt electrolyte in sodium liquid metal batteries. Additionally, this electrolyte facilitates the formation of a stable and NaF‐rich cathode electrolyte interphase (CEI) on the alloy cathode, enabling stable cycling at an unprecedentedly low ...

Enhancing Anode‐Free Lithium Metal Batteries: A Lightweight MPTS‐MXene Current Collector for Superior Performance and Energy Density

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces an MPTS‐modified MXene current collector for anode‐free lithium metal batteries (AFLMBs). A key advantage of MPTS‐MXene is its ultralight weight, only 15% as heavy as standard copper per unit volume. Its special layered structure and Si‐O rich surface help lithium deposit smoothly and flat, while forming a protective layer that ...

Molecular Interfacial Chelation Enables Wide‐Temperature Aqueous Zinc‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces a chelating additive for wide‐temperature aqueous zinc‐ion batteries. Methionine‐chelated zinc adsorb onto the Zn(002) plane and release Zn2+ in situ, forming a zinc‐ion‐rich buffer reservoir at the electrode/electrolyte interface, enabling aqueous zinc‐ion batteries to exhibit stable cycling performance over the temperature range

Time-of-flight secondary ion mass spectrometry of industrial materials

Analytica Chimica Acta, 1999
Abstract Surface phenomena are important in numerous technological areas, such as adhesion, friction, biocompatibility, catalysis, polymer science or composite research. Most of the critical parameters affecting the stability and specific response of industrial products to the environment are controlled by the chemical composition of the uppermost ...
