Special Issue Information

Dear Colleagues,

In recent years, global warming and environmental pollution have attracted more attention due to the use of fossil fuels. Sustainable and clean power generation technologies can be assumed as potential replacement candidates for current oil/coal methods and their related issues. However, reliable energy access remains a challenge. The challenge of providing adequate power on an indefinite basis without causing long-term damage to the environment, while also reducing and controlling energy consumption and preserving natural resources, requires a versatile means of energy conversion and storage. Therefore, the development of renewable and sustainable energy storage systems has accelerated. Electrochemical power source devices, such as fuel cells, supercapacitors, and batteries, have been utilized in portable electronic devices and hybrid vehicles that convert the energy of electrochemical phenomena directly into electrical current and power.

This Special Issue aims to attract all researchers working in this research field and will collect new findings, operational features, and major types of electrochemical power sources and will provide future applications of devices. Research manuscripts, as well as a limited number of review manuscripts, are encouraged in the following areas:

  • Fuel cells;
  • Batteries;
  • Capacitors;
  • Energy storage;
  • Sustainable energy and engineering systems;
  • Structure–properties relationship;
  • Electrochemical solar energy conversion;
  • Environmental effects;
  • Applications;
  • Recycling.

The design, synthesis, and application of composite materials based on manganese dioxide (MnO2) for energy storage are pivotal in advancing efficient, sustainable, and high-performance energy storage systems. The MnO2 is widely recognized for its abundance, low cost, environmental friendliness, and excellent electrochemical properties, making it a promising candidate for use in supercapacitors, batteries, fuel cells, and other energy storage systems. This study offers a comprehensive overview of how various materials influence the performance of MnO2 as an energy storage medium. Specifically, the design of composite materials is examined with respect to morphological control, integration with conductive additives, doping strategies, and structural engineering, all of which impact the final material properties. Additionally, the influence of diverse synthetic techniques—including hydrothermal synthesis, electrochemical deposition, sol–gel processing, co-precipitation, and templating methods—is evaluated. The latest attempts through which the developed composites showcase improved structural stability, inherent conductivity, and electron mobility compared to the original first material are presented in this review article. The presented results have been quite promising for the synthesis of great-performing materials with improved electrochemical data compared to that of MnO2 alone, competing with other significant energy storage materials. This review highlights future prospects for the development of state-of-the-art devices, large-scale production applications, and the use of environmentally friendly materials and methods. It is anticipated that this research will provide valuable insights to facilitate further improvements in performance and broaden the scope of practical applications in this rapidly evolving field of composite materials.

High-temperature fuel cells and electrolyzers, particularly molten carbonate fuel cells (MCFCs) and Molten Carbonate Electrolyzers (MCEs), are expected to play a critical role in clean power generation, hydrogen production, and integrated CO2 separation. Unfortunately, despite their potential, these technologies have not yet reached full commercialization. The main reason for this is material degradation. In particular, the corrosion of metallic components continues to be a leading cause of performance loss and system failure. This review provides a comprehensive assessment of degradation mechanisms in MCFC and MCE systems. It examines key metallic components, such as current collectors and bipolar plates, focusing on the performance of commonly used materials, including stainless steels and advanced alloys, under prolonged exposure to corrosive environments. To address degradation issues, this review evaluates current mitigation strategies and discusses material selection, protective coatings application, and the optimization of operational parameters. Advances in alloy development, coatings, surface treatments, and process controls have been compared in terms of effectiveness, scalability, and long-term stability. The review concludes with a synthesis of current best practices and future directions, emphasizing the need for integrated, multi-functional solutions to achieve the lifetimes required for full commercialization. By linking materials science, electrochemistry, and systems engineering, this review offers directions for the development of corrosion-resistant MCFC and MCE technologies in support of a hydrogen-based, carbon-neutral energy future.
