A boom of electrospinning of nanofibers in energy applications arose over the last years.
The electrospinning technique is currently also being used in the development of membranes and coatings geared towards energy-related products and applications: batteries, capacitors and other devices for energy storage, promoting chemical catalysis in devices for the production of green hydrogen or other substances, dye-sensitised solar cells that include an electrospun layer to promote electronic conduction, etc.
In all these possible applications, the fact that electrospun membranes offer high porosity and large surface areas makes them suitable structures for highly efficient ion transfer. In addition, depending on the materials used and the structure generated by electrospinning, acceptable thermal stability can be achieved over time, with appropriate mechanical properties depending on the application, and a reduction in degradation rates in the charging and discharging processes (in the case of electrospun separators). These properties of electrospum membranes are part of the reasons why the electrospinning of nanofibers in energy applications is more and more used by researchers and some manofacturers as well.
Another important detail in the current era is that both graphene and graphene oxides can be processed through electrospinning. Graphene is a material with great aspirations in the generation of more efficient products in the field of energy storage and transmission.
All this means that electrospinning (primarily) as well as electrospraying technology is increasingly present in new developments aimed at improving performance and/or reducing costs in different energy-related applications.
