Special Issue Information

Dear Colleagues,

Advanced energy conversion and storage technology is critical for developing renewable energy. For instance, high-density, long-life energy storage devices (such as batteries, supercapacitors) can store electricity converted from renewable sources (such as wind, solar and wave energy), and highly efficient electrolysis devices can convert excess electricity into hydrogen or carbon fuel. Whether an energy storage device or electrolysis device, their performance mainly depends on the structure of the used electrode coatings and this coating's activity and stability. Due to the lack of in-depth research on electrode coatings, various kinds of electrode reactions generally have the problems of slow kinetic speed and low energy conversion efficiency. Therefore, optimizing the structure of electrode coatings and enhancing their activity and stability are key to improving the energy conversion and storage technology, which is of great significance for the development and application of renewable energy. This Special Issue focuses on the design of electrode coatings and the preparation and modification of electrode coating materials or electrocatalysts, aiming to provide a forum for communicating scientific and technological advances in the areas of energy conversion and storage, bring together solutions to common problems in electrode reactions, and promote the development of energy conversion and storage technology. The topics of this Special Issues include, but are not limited to:

  • New findings related to the synthesis, fabrication, structure, properties, and performances of electrode coating materials or electrocatalysts;
  • The design and fabrication of electrodes;
  • The optimal use of energy resources;
  • The design and preparation of energy storage devices, e.g., lithium-ion batteries, lithium–sulfur batteries, zinc-ion batteries;
  • Various types of electrocatalysis, e.g., electrolysis of water, electrocatalytic nitrogen reduction, electrocatalytic carbon dioxide reduction;
  • The analysis and optimization of energy processes;
  • Sustainable energy systems.

In this study, we fabricate a counter electrode by coating a Pt ribbon onto a fluorine-doped tin oxide glass substrate with a Pt layer. The Pt ribbon gives rise to a protrusive structure of the counter electrode, produced by photolithography, sputtering and lift-off processes. The experimental results reveal that the photoelectric efficiency of the dye-sensitized solar cell (DSSC) with the Pt ribbon (5.32%) is 21% higher than that of the DSSC without a Pt ribbon (4.38%). This infers that Pt ribbons can increase the photoelectric efficiencies of DSSCs. The DSSC with the Pt ribbon has a large photoelectric efficiency of 5.32%, not only because the protrusive structure has specific channels for directional electron transport, but also because of its large surface area. The method that is proposed herein has the advantages of a low production cost and easy fabrication that can be applied to various electrode structures. Full article

Silicon anodes have been considered one of the most promising anode candidates for the next generation of high-energy density lithium-ion batteries due to the high theoretical specific capacity (4200 mAh g−1) of Si. However, high lithiation capacity endows silicon anodes with severe volume expansion effects during the charge/discharge cycling. The repeated volume expansions not only lead to the pulverization of silicon particles and the separation of electrode materials from the current collector, but also bring rupture/formation of solid electrolyte interface (SEI) and continuous electrolyte consumption, which seriously hinders the commercial application of silicon anodes. Structural design and optimization are the key to improving the electrochemical performances of silicon anodes, which has attracted wide attention and research in recent years. This paper mainly summarizes and compares the latest research progress for the structural design and optimization of silicon anodes. Full article
