Special Issue Information

Dear Colleagues,

Sustainable and environmentally friendly energy storage and conversion technologies are essential to satisfy the dramatically increasing global energy demand and reduce dependence on non-renewable fossil fuels. The development of novel materials plays a key role in improving the properties and performances of devices in varied electrochemical energy applications, including batteries, supercapacitors, flow batteries, fuel cells, hydrogen storage, photocatalysis and thermal energy storage.

This Special Issue will present recent advances in materials used in all electrochemical forms of sustainable energy harvesting, conversion, storage and utilization, including, but not limited to, the following:

  • Batteries;
  • Supercapacitors;
  • Flow batteries;
  • Fuel cells;
  • Electrocatalysis and electrocatalysts for energy conversion and storage;
  • Photocatalysis and photocatalysts for water splitting;
  • Hydrogen production and storage;
  • Thermochemical, piezoelectric and thermoelectric materials and devices;
  • Flexible, self-powered and integrated energy devices/systems.

We invite you to submit a manuscript for inclusion in this Special Issue. Full papers, communications and reviews are all welcome.

Sodium-ion batteries (SIBs) represent a topic of extreme interest in the research field, especially because the materials used are cheaper than those in lithium-ion batteries (LIBs). In SIBs, the choice of cathodes and electrolytes is very important because they will affect the energy density, cycling stability, and safety of the battery. This work focuses on the prospect of hybrid electrolyte cells that incorporate ionic liquids (ILs) into organic liquids in order to improve the safety and performance of SIBs. Organic solutes make ionic conductivity higher due to larger IL electrochemical windows, good thermal stability and low volatility. They have some issues like flammability, dissolution, and transport limitations, but these aspects could be solved by using hybrid electrolyte systems. In this study, we investigate the effect of using different salts and solvents on the characteristics of the SIBs. We analyze ionic conductivity, electrochemical stability, and the development of stable solid electrolyte interphase (SEI) in the SIBs by using hybrid electrolytes. Additionally, we demonstrate that the addition of ILs to organic electrolytes can improve their thermal stability, so as a result, the safety and lifecycle of the battery will be increased. In conclusion, this research shows how hybrid electrolytes could have great potential for SIB battery technology in high-performance and large-scale energy storage applications. Full article
