Fluorinated Reduced Graphene Oxide as an Interlayer in Li–S Batteries

open access: yesChemistry of Materials, 2015
We report on the synthesis of fluorinated reduced graphene oxide (F-rGO) by a direct fluorination of reduced graphene oxide (rGO) with F2 or XeF2/BF3 in anhydrous HF. Characterization performed by high-angle annular dark-field (HAADF)-scanning transmission electron microscopy (STEM) and NMR confirmed the formation of C–F bonds, which is also supported ...

Layer-by-Layer Assembled C/S Cathode with Trace Binder for Li–S Battery Application

open access: yes, 2015
The C/S cathode with only 0.5 wt % binder, composed with Nafion and PVP, was assembled layer-by-layer for lithium–sulfur battery (Li–S) application. It achieved excellent binding strength and battery performance compared to the cathode with 10 wt % PVDF,

An Image Based 3D Modelling Framework for Li-S Batteries

open access: yes, 2022
Traditionally, 1D volume-averaged continuum approaches are used to model Li-S battery performance at varying C-rates. For the first time, we present a working three-dimensional electrochemical model of a Li-S battery based on real electrode ...

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Accelerating S↔Li2S Reactions in Li–S Batteries through Activation of S/Li2S with a Bifunctional Semiquinone Catalyst

open access: yes, 2023
The reaction rate bottleneck during interconversion between insulating S8 (S) and Li2S fundamentally leads to incomplete conversion and restricted lifespan of Li−S battery, especially under high S loading and lean electrolyte conditions.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

open access: yesAdvanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.
