Special Issue Information

Dear Colleagues,

Energy availability and efficient storage are crucial for technological advancement, influencing everything from renewable integration to portable electronics. Politically, energy security has shaped global economies and policies, driving innovation in cost-effective and high-performance storage solutions. Advances in energy production through solar, hydroelectric, wind, and electrochemical or photoelectrochemical water splitting must be matched by equally effective energy storage technologies.

Energy storage ensures immediate accessibility, stabilizes power grids, and supports applications in transportation and commercial sectors. Batteries, supercapacitors, and hydrogen storage systems paired with fuel cells enable flexible, on-demand energy delivery. Recent innovations in electrochemical energy storage focus on novel materials, advanced manufacturing techniques, and cost-efficient fabrication while maintaining high stability, durability, and energy density.

This special issue highlights cutting-edge strategies for designing and developing affordable yet high-performance electrochemical energy storage devices. We invite original, high-quality research emphasizing long-term stability, cycling durability, and optimized energy density.

The topics covered in this issue are broad. Some examples are:

  • Fundamentals of electrochemical energy storage
    • Thermodynamics and kinetics, redox reactions and charge transfer, Nernst equation, mass transport and diffusion.
  • Battery technologies
    • Lithium-ion, sodium-ion, lithium-sulfur, solid-state, metal-air, flow and multivalent-ion batteries.
  • Capacitors and hybrid storage devices
    • Supercapacitors, ultracapacitors, lithium-ion capacitors and asymmetric capacitors.
  • Hydrogen energy storage
    • Water electrolysis, hydrogen storage and fuel cells.
  • Electrode and electrolyte materials
    • Carbon, metal oxides and sulfides, polymers and organic materials, solid electrolytes, ionic liquids and deep eutectic solvents.
  • Performance metrics and testing
  • Advanced characterization techniques
  • Manufacturing and scalability
  • Emerging trends and future directions

Metal-free electrodes are essential to promote electrochemical reactions, the core of sustainable energy resources. In search of better carbon-based electrode materials, we have explored several spatial arrangements of boron (B) within proximity in the graphene lattice, as evident in recent experimental observations. Multi-boron substitution enriches sites by tuning electronic structure and strengthens binding of key intermediates of oxygen reduction, oxygen evolution, and hydrogen evolution reactions facilitating electrocatalytic performance. Our optimal B-doped site shows near thermo-neutral H adsorption (ΔGH*∼±0.4eV), consistent with experiments. The overpotentials are highly sensitive to the dopant motifs and the spread among configurations shows that experimentally accessible multi-B doping can serve as a practical active site engineering knob to achieve optimized multi-functional performance. In parallel, we find that specific multi-B configurations selectively capture and pre-activate NOx (NO/NO2) under ambient conditions while retaining weak affinity for NH3. These sites also interact with SO2 and related hazardous species, enabling selective air filtration and targeted NOx control within the electrocatalytic scope of this study. Full article

The intermittency of renewable-based power is a major barrier for long-term supply of clean energy, which necessitates the development of reliable solutions for clean energy storage and transition towards a carbon-neutral economy. Although hydrogen has emerged as a promising clean energy carrier to address this, its high compressibility requires safe, efficient and practical storage technologies for widespread deployment. Surface storage technologies for hydrogen have garnered attention due to their mobile and stationary applications, paving the way for a future hydrogen-based economy. This review provides a comprehensive review of surface hydrogen storage technologies, covering metal hydrides, metal-organic frameworks (MOFs), liquid organic hydrogen carriers (LOHCs), glass microspheres, capillary arrays, etc. Where previous reviews mostly address the chemistry behind these storage technologies, this study highlights practical integration and techno-economic assessment. Comparative analysis reveals that while LOHC and hydrides dominate in Technology Readiness Level, MOFs and carbohydrate-based systems offer high gravimetric potential, though they are currently quite costly. Other challenges like thermal management and large-scale regeneration remain critical for practical deployment. Moreover, recent advancements in Artificial Intelligence and Machine Learning offer unique insights, demonstrating their growing role in material screening, performance prediction, and the optimization of storage system designs. This review outlines the key challenges and research pathways required to support future deployment. Full article
