Special Issue Information
Dear Colleagues,
Nowadays, the overall need for green energy harvesting and storage materials, with a proven record for scale-up and low-carbon manufacturing, is a significant fact. With novel, low-cost materials and new performance-enhancing technologies pushing against the existing ones, electrochemical systems will continue to play an important role in the exploitation of renewable energy sources on a worldwide scale. Electrochemical systems rely on porous electrodes with personalized design and chemical potential for specific purposes, such as the anodes and cathodes in fuel cells, batteries and electrolyzers. Upon manufacturing, the electrode materials are often processed in the form of powders with well-defined composition, grain-size, and shape. Further modifications of the electrode surface aim to enhance the overall device performance and durability by also reducing the risks associated with safety upon operation. For that, the physical, chemical, and topological properties of electrodes are manipulated in a way that the processes associated with the charge transfer and ion intercalation at the electrode–electrolyte interface are faster, more favorable and also reversible. In this picture, although significant progress has been achieved so far, the detailed mechanisms of performance enhancement are insufficiently understood to foster the development of more efficient electrode architectures. From this perspective, it is expected that the future work will bridge the gap in knowledge toward novel electrochemical applications with enhanced performance, durability, and safety.
This Special Issue welcomes extensive topics on modified surface cathode materials for efficient energy storage and conversion, including fuel cells, electrolysis, batteries, supercapacitors, and photovoltaics. Theoretical studies, manufacturing methods, experimental investigations, and numerical simulations are equally considered.
This Special Issue aims to cover the following fields:
- Theoretical aspects related to modified cathodes with enhanced kinetics of charge transfer and ion integration at the cathode–electrolite interface;
- Novel manufacturing methods of modified cathodes with enhanced specific area and electrochemical activity, with a high potential for up-scale, including but not limited to thin film coating, functionalization and 3D particle decoration for surface catalitic activation and degradation passivation;
- Non-destructive, in-operando experimental techniques and methods to assess the overall performance and durability of cathods upon prolonged operation, including the irreversible process upon cycling;
- Numerical calculations and simulations for cathode integration in electrochemical systems in relation to device performance, durability, and safety issues.
We look forward to receiving your contributions.
