Regional Characteristics in Ultradeep MXene Slit Nanopores: Insights from Molecular Dynamics Simulation

Langmuir, Journal Year: 2025, Volume and Issue: unknown

Published: April 8, 2025

The presence of slit nanopores in MXene materials inevitably influences the electrochemical performance supercapacitor electrodes. However, most studies focus on experimental approaches, lacking microscopic-scale analysis. Here, we performed molecular dynamics (MD) simulations to thoroughly analyze and predict ion transport pathways energy storage mechanisms MXene/ionic liquid (IL) supercapacitors with ultradeep nanopores. simulation results indicate that during charging process, counterions migrate from bulk region into electrode pores, forming a counterion layer near surface, while some co-ions gradually exit pores. When is completed, distinct layering structure emerges. As interlayer spacing varies, distribution pores exhibits regional characteristics: ordered region, stable electrical double-layer (EDL) maintained, whereas deeper mixed persistent co-ion significant disorder are observed. Dominated by total variation decreases as decreases, changes 8526.52, 7443.52, 6640.99 kJ·mol-1 at spacings 1.2, 1.0, 0.8 nm, respectively, representing reductions approximately 12.7 22.1% compared 1.2 nm. In after compensating for interaction between counterions, contribution increases decreasing spacing, reaching 123, 153, 176% respectively. An increasing amount offset interactions related co-ions, ultimately leading observed differences. These findings offer new insights impact nanopore provide theoretical guidance optimizing design.

Flexible solid-state-based supercapacitors are in demand for the soft components used electronics. The increased attention paid toward solid-state electrolytes could be due to their advantages, including no leakage, special separators, and improved safety. Gel polymer (GPEs) preferred energy storage field, likely owing safety, lack of compatibility with various separators as well higher ionic conductivity (IC) than traditional solid electrolytes. This review covers classification, properties, configurations different GPE-based recent advancements that have occurred this area storage. Ionic liquid (IL)-based materials popular GPEs electrochemical can prepare unprecedented flexible great IC wide potential range. A comparative assessment GPEs-based reveals a majority them, value specific capacitance is generally under 1000 F g−1, density reaches around 125 Wh kg−1, power seen less 1500 W kg−1. results research serve an essential reference upcoming scholars, significantly improve our comprehension efficacy GPE-containing supercapacitors.
