NiFe‐NO3 Layered Double Hydroxide as a Novel Anode for Sodium Ion Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
This study demonstrates, for the first time, the effectiveness of using LDH as an anodic material in SIB. The material is stable and show high specific capacity, the reaction mechanism has been thoroughly investigated and comprehensively described and involves a phase change reaction followed by sodium intercalation.

Enhancing the Capacitance of Poly(Heptazine Imide) Electrodes in Aqueous Electrolytes via Hybrid Material Design

open access: yesBatteries &Supercaps, EarlyView.
This work highlights the synthesis of a potassium poly(heptazine imide) K‐PHI@carbon hybrid material. The design of the hybrid improves the electrochemical properties of the semiconducting carbon nitride enabling the investigation of interaction between K‐PHI and different cations from the electrolyte.

Modification of the Solid Electrolyte Interphase on SiGr Electrodes by a Prelithiation Method Using Passivated Lithium Metal Powder

open access: yesBatteries &Supercaps, EarlyView.
Prelithiation of SiGr electrodes by direct contact with passivated lithium metal. powder creates a solid electrolyte interphase (SEI) layer prior to cycling which is superior to the one conventional SEI layer produced during the formation cycles in nonprelithiated cells.

Investigation of Degradation Pathways in Fluoroethylene Carbonate Based Electrolytes via Chromatographic Techniques

open access: yesBatteries &Supercaps, EarlyView.
In this article, decomposition products of the lithium ion battery electrolyte component fluoroethylene carbonate (FEC) are examined in varying amounts by means of liquid chromatography coupled to high‐resolution accurate mass spectrometry. Based on identified degradation products, FEC degradation mechanism is further postulated and confirmed, whereby ...
