Dynamics of charge fluctuations in nanocapacitors: Effects of salt concentration and electrode metallicity from Brownian dynamics

Electric double-layer capacitors (EDLCs) rely on the dynamical response of confined electrolytes to store and release charge, yet the interplay between ion transport, electrostatic interactions, and electrode metallicity remains poorly understood at the nanoscale. In this work, w...

Soft-Templated Carbon Models Elucidate the Anomalous Increase of Capacitance in Nanopores

Abstract Supercapacitors are electrochemical energy-storage devices distinguished by rapid charge–discharge and high power density. The observation of anomalously enhanced capacitance in nanoporous carbons challenged classical descriptions of double-layer charging and stimulated...

How fluorinated cyclic ether shapes localized high concentration electrolytes

Localized high concentration electrolytes (LHCEs) have emerged as a transformative choice, simultaneously exhibiting good electrochemical stability, sufficiently fast ionic transport, and improved rate capability. The design principle is to dilute the conventional electrolyte wit...

Machine Learning and Molecular Simulations Reveal Mechanisms of ZIFs Polymorph Selection

metal-organic frameworks (MOFs) exhibit a remarkable degree of polymorphism. Because of their promising industrial applications, many research groups have investigated phase transitions, phase diagram and relative stability of these polymorphs. There is now wide consensus in the...

Accelerating charging dynamics of electric double-layer capacitors

Electric double-layer capacitors (EDLCs), consisting of an ionic fluid between two metallic electrodes, are electrochemical energy storage devices complementary to batteries, allowing for a faster charge/discharge. The charging dynamics in response to a voltage step features a va...

Multi‐Scale Investigation of Supramolecular Organogels Assembled From Pt(II)‐Salphen Complexes

Supramolecular metallogels based on platinum(II) complexes have attracted growing interest due to their tunable photophysical properties. However, the potential of Pt(II)-salphen complexes as low-molecular-weight gelators remains largely unexplored. Here, we report a series of Pt...
