Role of Silicon as Structural Stabilizer and Redox‐Active Element in Multicomponent (Sn, Sb, Fe, Si) Alloy Electrodes for Na‐Ion Batteries

open access: yesBatteries &Supercaps, EarlyView.
Multicomponent alloys based on Sn, Sb, Si, and Fe are prepared via ball milling and tested as Na‐ion battery electrodes. Despite its promise as a high‐capacity material, Si is found to be redox‐inactive. However, it acts as a structure stabilizer in multicomponent alloys, enabling stable cycling.Metal alloys are attractive electrode materials for ...

Improving Gr/SiO Negative Electrode Formulations: Effect of Active Material, Binders, and Single‐Walled Carbon Nanotubes

open access: yesBatteries &Supercaps, EarlyView.
The study examines Gr/SiO negative electrode formulations utilizing prelithiated SiO (Li–SiO) and single‐walled carbon nanotubes (SWCNTs), demonstrating reduced irreversible losses and enhanced electrochemical performance. By reducing binder content and incorporating SWCNTs, high active material content and improved mechanical integrity are achieved ...
