Special Issue Information

Dear Colleagues,

The rapid development of renewable energy systems and electrified transportation demands high-performance energy storage technologies with enhanced energy density, long-term stability, and safety. Recent breakthroughs in materials science have significantly advanced the design and application of energy storage materials, including novel electrode architectures, electrolyte interfaces, and AI-driven material discovery. However, challenges such as capacity degradation, dendrite formation, interfacial incompatibility, and limited thermal stability persist, necessitating innovative solutions to bridge the gap between laboratory research and industrial applications.

This Special Issue will highlight cutting-edge research on the structural engineering, design strategies, and practical implementations of advanced energy storage materials. We welcome contributions that address both fundamental mechanisms and scalable applications, with a focus on interdisciplinary approaches combining computational modeling, experimental synthesis, and real-world device integration.

This Special Issue covers, but is not limited to, the following themes:

  • Novel Electrode Materials and Architectures;
  • Electrolyte and Interface Engineering;
  • AI-Driven Material Discovery and Optimization;
  • Advanced Characterization and Theoretical Insights;
  • Scalable Synthesis and Device Integration.

In this paper, a simple hydrothermal approach is employed to prepare nitrogen-doped graphene quantum dots (N-GQDs) with controllable size and structural features, where citric acid and ethylenediamine served as the carbon and nitrogen precursors, respectively. The influence of hydrothermal temperature and duration on the structural features, surface chemistry, and electrochemical behavior of N-GQDs is systematically investigated. The capacitive behavior of N-GQD electrodes exhibits typical pseudocapacitive characteristics, primarily attributed to the surface functional groups. The NG-2 electrode (180 °C, 6 h) demonstrates a specific capacitance of 309.8 F g−1 at 1 A g−1 and maintains 98.1% of its initial capacitance after 8000 cycles, confirming excellent stability. Density functional theory (DFT) results demonstrate that the co-presence of graphitic and pyrrolic nitrogen induces a synergistic modulation of the electronic structure, resulting in improved charge-transfer kinetics and surface reactivity of N-GQDs compared to single-type nitrogen doping. Additionally, NG-2//activated carbon (AC)-asymmetric supercapacitor (ASC) achieves an energy density of 22.5 Wh kg−1 at 500 W kg−1 and maintains outstanding cycling stability. This work provides valuable insights into the design and application of N-GQDs for advanced energy storage devices. Full article

Electricity is currently essential for the operation of most modern devices, with significant electrification being observed in all areas. This development has led to an increased demand for solutions that enable energy storage appropriate for a given application, which is currently solved by installing batteries with adequate capacity. This article presents an approach utilizing composite materials that combine both structural and energy storage features. The most frequently discussed components of such materials in the literature are compared, divided into those that contribute to the structural functions of the composite and those that provide additional functionality. The methodology for developing our literature analysis and for comparing materials is given. The results of our publication analysis are then presented, based on the type of integration of multifunctional elements, structural materials, resins, electrolytes, and production methods. The influence of these parameters on the mechanical and electrochemical properties of multifunctional composites is examined. The different materials are compared, and the best ones selected based on appropriate criteria. The current state of knowledge regarding simulations of such materials is presented, and the potential applications of multifunctional composites are reviewed. Finally, key research gaps are identified, suggesting directions for future work. Full article
