First Electrodeposition of Silicon on Crumbled MXene (c‐Ti3C2Tx) for High‐Performance Lithium‐Ion Battery Negative Electrode

open access: yesBatteries &Supercaps, EarlyView.
To meet the demand for high‐capacity, stable Li‐ion batteries, this study develops a silicon‐based nanocomposite using a two‐step synthesis. Crumbled Ti3C2Tx (c‐Ti3C2Tx) is formed via electrostatic interaction with KOH, followed by the electrodeposition of an amorphous silicon layer.

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.

On the Description of Electrode Materials in Lithium Ion Batteries Based on the Quantification of Work Functions

open access: yesBatteries &Supercaps, EarlyView.
Ionic and electronic work functions of prototypical electrode materials, i. e. LixFePO4 and LixMn2O4, in lithium ion batteries have been measured as a function of x, i. e., the state of charge. The results are discussed in the context of thermodynamic Born cycles. It is concluded that interfacial properties must be highly relevant.

Direct Powder Adhesion Method of Quinone‐Based Aqueous Supercapacitor for Roll‐to‐Roll Process

open access: yesBatteries &Supercaps, EarlyView.
Introducing a novel Direct Powder Adhesion (DPA) method for quinone‐based supercapacitors that simplifies electrode fabrication, enhances rate performance, and supports high‐rate charging and discharging. Compared to conventional pressing, the DPA method provides lower electrode density, higher conductivity, and enhanced specific capacity ...
