Photophysical and Chiroptical Properties of Pyrazino‐Phenanthroline‐Helicene Derivative and its Rhenium(I) Complex

open access: yesChemistry – An Asian Journal, EarlyView.
The preparation and characterization of the first helical pyrazino‐phenanthroline ligand, namely [4]helicene‐pyrazino[2,3‐f][1,10]phenanthroline (H4PP) and its corresponding Re(CO)3Cl complex (Re‐H4PP) are described. The photophysics and chiroptics (circular dichroism and circularly polarized luminescence) of these new chiral systems are thoroughly ...

Stable Long‐Term Cycling of Room‐Temperature Sodium‐Sulfur Batteries Based on Non‐Complex Sulfurised Polyacrylonitrile Cathodes

open access: yesBatteries &Supercaps, EarlyView.
Sulfurised polyacrylonitrile (SPAN) has been synthesized using a simple and scalable method, achieving a high sulfur content covalently linked to its framework. The development of SPAN cathodes demonstrates significant improvements in combating capacity fading and the shuttle effect in sodium‐sulfur (Na−S) batteries.

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.

The Value Chain of Sustainable Dual Carbon Sodium Ion Capacitors

open access: yesBatteries &Supercaps, EarlyView.
Sodium‐ion capacitors (SICs) bridge the energy‐power gap between batteries and supercapacitors, offering sustainable and scalable energy storage solutions. This review provides a 360‐degree perspective on SIC technology, covering material choices, presodiation strategies, manufacturing challenges, applications and life cycle assessment to ensure ...
