Construction of high-performance sodium ion hybrid capacitors based on MXene surface modulation and electrolyte matching

The Journal of Chemical Physics, Journal Year: 2025, Volume and Issue: 162(12)

Published: March 28, 2025

Sodium-ion hybrid capacitors have garnered significant attention due to their high power and energy densities, as well the abundance of sodium reserves. However, mismatch between anode cathode dynamics is biggest barrier improving performance. To address this issue, we propose a strategy for preparation porous MXene by hydrogen peroxide (H2O2)-controlled etching solve capacity degradation ion diffusion limitation, which are caused van der Waals forces nanosheets. This approach facilitates realization three-dimensional channels with both vertical horizontal pathways, significantly enhancing availability active sites rate. By adjusting amount oxidant, (P-MXene-2) an optimal pore size range was obtained. The assembled half-cell has 180 mAh g−1 at rate 0.05 A g−1. Furthermore, combining carbon electrolyte screening, SIHC density 110.6 Wh kg−1 1000 W 71.1 20 kW successfully constructed. study provides useful insights into design electrodes storage applications.
