“…Second, fast evaporation of the solvent during electrospinning procedure does not allow the polymer chains and lithium salts to form polymer/salt crystalline regions. So, concentration of the free lithium ions increases in the electrospun membranes, leading to enhancement of the ionic conductivity [ 43 , 168 ]. It is worth noting that electrochemical behavior of the electrospun mats highly depends on the morphology of the fabricated fibers.…”

Electrochemical devices convert chemical reactions into electrical energy or, vice versa, electricity into a chemical reaction. While batteries, fuel cells, supercapacitors, solar cells, and sensors belong to the galvanic cells based on the first reaction, electrolytic cells are based on the reversed process and used to decompose chemical compounds by electrolysis. Especially fuel cells, using an electrochemical reaction of hydrogen with an oxidizing agent to produce electricity, and electrolytic cells, e.g., used to split water into hydrogen and oxygen, are of high interest in the ongoing search for production and storage of renewable energies. This review sheds light on recent developments in the area of electrospun electrochemical devices, new materials, techniques, and applications. Starting with a brief introduction into electrospinning, recent research dealing with electrolytic cells, batteries, fuel cells, supercapacitors, electrochemical solar cells, and electrochemical sensors is presented. The paper concentrates on the advantages of electrospun nanofiber mats for these applications which are mostly based on their high specific surface area and the possibility to tailor morphology and material properties during the spinning and post-treatment processes. It is shown that several research areas dealing with electrospun parts of electrochemical devices have already reached a broad state-of-the-art, while other research areas have large space for future investigations.

“…Nanofibers are currently one of the most popular polymer structures with various applications, mainly due to the large surface‐to‐volume ratio and high porosity 1 . Many applications have been reported for this structure in areas such as composite fabrication, 2 filtration, 3 sensors and actuators, 4,5 lithium‐ion batteries, 6 drug delivery 7–9 and tissue engineering 10–12 . The nanofibers are produced employing various techniques, among which the electrospinning method is of special importance due to the simplicity and the convenient engineering.…”

As a special structure and due to the unique properties of submicron-scale fibers and electrical conductivity, conductive nanofibers recently attracted further attention in various fields, especially tissue engineering. This study aimed to coat poly (glycerol sebacate) (PGS) nanofiber/poly(caprolactone) (PCL) as a widely used combination in the fields of medicine with poly(pyrrole) (PPy) as a conductive polymer, subsequently studying and optimizing production process variables using response surface methodology (RSM). The samples were examined for morphological and structural, and their electrical conductivity and electroactivity were measured using a fourpoint probe system and a cyclic voltammetry, respectively. The electrospinning conditions for constructing the substrate nanofibers with the smallest diameter were optimized. The monomer concentration of 0.05M and the polymerization time of 3.3 h exploiting the RSM were also considered as the optimal conditions for obtaining coated-nanofibers with the smallest diameter and desired electrical conductivity (0.001 S/cm). The structural findings confirmed the successful synthesis of PGS and PPy. The conductive-nanofiber produced under optimal conditions revealed good mechanical properties (tensile strength = 3.12 ± 0.19 MPa and elongation at break = 80.26 ± 13.71%). The highest biocompatibility was observed for the sample synthesized with the pyrrole concentration of 0.05M, which can be a suitable candidate for application in cardiac tissue engineering.

“…[30] Finally, electrospinning of polymer membranes has been shown to give superior ionic conductivity compared with solution cast methods. [31] In recent studies, Banitaba et al showed that the incorporation of inorganic fillers in the electrospinning process is possible. [32] For the scalable manufacturing of cathodes for high energy applications, a viable process route is the dispersion of the homogenized raw materials in a solvent with subsequent wet coating and drying.…”

For the development of all‐solid‐state batteries (ASSBs), it is of major importance to identify scalable process routes, to define limits of the processing technologies, and to investigate how the electrochemical performance can be influenced by the manufacturing process. Herein, two scalable and sustainable production chains are presented, extrusion‐ and direct calendaring of composite cathode granules, which are suitable for industrial series production. Both process routes start with a melt granulation step to desagglomerate the carbon black to homogenize the cathode components. By adjusting the granulation process parameters the process time and, thus, the production costs can be reduced. The polymer solid electrolyte distribution induced by the process shows a considerable influence on the rate capability of the ASSB cells. The manufactured pouch cells reach ≈140 mAh g−1 at 0.1C and 75/50 mAh g−1 at 1C discharge rate and 80 °C for extruded‐calendered and directly calendered electrodes, respectively, which is comparable to other recent publications on laboratory scale.
