Abstract Lithium‐ion capacitors (LICs) hold great promise by merging the benefits of lithium‐ion batteries and supercapacitors. However, their performance is frequently constrained a disparity in kinetic properties cathode anode. This study introduces dual graphene‐based approach aimed at improving efficiency functionality LICs demonstrates successful large‐scale production graphene (SHSG) using self‐propagating high‐temperature synthesis method. In cathode, SHSG forms continuous network, reducing interfacial resistance, enhancing conductivity achieving capacity 85.9 mAh g −1 . anode, improves ion diffusion reaction interfaces, increasing from 247.9 to 286.6 A full LIC cell assembled with 10% both electrodes peak energy density 106.3 Wh kg retains 33 4.4 kW , which calculated based on total mass electrodes. Additionally, 1100 F pouch developed, showcasing its potential for practical storage. work underscores transformative role optimizing advancing storage technologies.

Enhanced Electrocatalytic Performance of P-Doped MoS2/rGO Composites for Hydrogen Evolution Reactions

Molecules, Journal Year: 2025, Volume and Issue: 30(6), P. 1205 - 1205

Published: March 7, 2025

This study is based on the strategies of composite and element doping. Herein, P-MoS2/rGO materials were synthesized using a solvent-assisted hydrothermal method. The MoS2 nanosheets uniformly vertically grown rGO; meanwhile, optimized structure was achieved by P doping, resulting in improved catalytic performance structural stability. Under alkaline conditions, catalyst exhibits good electrocatalytic activity, demonstrating Tafel slope 70.7 mV dec−1 an overpotential 172.8 at 10 mA/cm2. Notably, even after 3000 consecutive LSV tests, curves still show high degree overlap, indicating exceptional
