The Oxidized Ti2(Al/Sn)C Behavior as Anode for Lithium‐ and Sodium‐Ion Batteries: The Role of the MAX Phase Order

open access: yesChemElectroChem, EarlyView.
The present study is dedicated to investigation of the performance of oxidized Ti2(Al/Sn)C system (211 MAX phases) as anode for lithium and sodium ion batteries. Their behavior has been rationalized as function of the tin content and as function of the MAX phase order, with detailed comparison with the 312 MAX phase analog series.

Cathode Materials for Proton Exchange Membrane Fuel Cells: From Metal and Metal Composite Catalysts to Carbon‐Supported Hybrids in Oxygen Reduction Reaction

open access: yesChemElectroChem, EarlyView.
This review highlights recent progress in the development of electrocatalysts for the oxygen reduction reaction in proton exchange membrane fuel cells (PEMFCs). Particular focus is given to structure–activity relationships, active site identification, and the role of noble and non‐noble metals, with insights into synthetic strategies and performance in

The Effect of Regioisomerism on the TADF Properties of Organic Dyes

open access: yesChemistryEurope, EarlyView.
The properties of TADF emitters are highly dependent on the chosen electron donor and acceptor, as well as the π‐system that links them together. Herein, we show that regioisomerism affects the physical properties of spirobifluorene‐based systems in solution, thin films and crystals.

Comprehensive insights into sodium storage in pitch‐derived porous hard carbon

open access: yesCarbon Energy, EarlyView.
The Na ions adsorbed in open pores generate most of the irreversible capacity. The entry of de‐solvated Na ions into the closed pores contributes significantly to the reversible capacity and is characteristic of a long plateau in the voltage profile. Intercalation is the main source of capacity for slope‐type hard carbons (HCs) but plays a minor role ...

Multifunctional Interface Engineering of Li13Si4 Pre‐Lithiation Additives With Superior Environmental Stability for High‐Energy‐Density Lithium‐Ion Batteries

open access: yesCarbon Energy, EarlyView.
An environmentally stable Li13Si4@PFPE/LiF pre‐lithiation additive is designed for universally applicable and scalable anode pre‐lithiation in the industrial Si‐based anode fabrication environment. The multifunctional pre‐lithiation additives achieve integration of active Li compensation, long‐term Li chemical structural stability in air, and solid ...
