“…The properties of PET stand it in good stead because of its suitable mechanical features, chemical resistance, thermal stability, high transparency/flexibility and low permittivity to gases. 3 Considering all of these positive features of PET it is not surprising that noncommercial applications of the polymer have also been sought in research-biased areas including force-sensing resistor materials, 4 nanofiber phototransistors, 5 rechargeable polymer batteries, 6 solar cells 7 and OLED devices. 8 One feature from these studies is the consistency in structure of the basic terephthalate core with any additional functionality arising from blending of additional agents.…”

“…The use of various polymers, copolymers, and polymer blends for fabrication of separators is the reported solution for the above discussed problems . The most commonly used polymers for preparation of separators are poly(vinylidene fluoride) (PVDF), poly(ethylene oxide) (PEO), poly(acrylonitrile) (PAN), polymethyl methacrylate (PMMA), poly(ethylene terephthalate) (PET), and copolymers of PVDF like poly(vinylidene fluoride‐hexafluoropropylene) (PVDF‐HFP), poly(vinylidene fluoride trifluoroethylene) (PVDF‐TrFE), and poly(vinylidene fluoride‐chlorotrifluoroethylene) (PVDF‐CTFE) …”

metric tons of carbon dioxide (CO 2 ) and other pollutants per year, which accelerate global warming and major climate changes. [2] In order to mitigate these serious issues caused by fossil fuels and to compete with the energy generating devices based on fossil fuels, renewable energy sources like solar energy, wind energy, bioenergy, and geothermal energy are potential alternative power resources. However, these renewable energy resources need highly efficient energy storage devices for integrating and well distribution of energy. Rechargeable battery technology with high energy, high power density, long life cycle capability, fast cycling rate, and reasonable cost is the possible solution to store energy obtained from these renewable sources. [3] Among many rechargeable energy storage devices, lithium-ion batteries (LIBs) are the promising energy sources for integrating renewable resources and high power applications, owing to high energy density, lightweight, high flexibility, slow self-discharge rate, high rate charging capability, long battery life, and environmental benignity. [4,5] The aforementioned attractive properties of rechargeable LIBs promote its utilization in the wide range of applications like laptops, cell phones, electric vehicle, hybrid electric vehicles, renewable power stations, stationary electric power, defense arsenal, subsurface exploration, thermal reactors, and space vehicles. [6][7][8][9] From the last 30 years, rapid development has been observed in LIBs technology. Presently, LIBs hold twofold energy density as compared to the first commercial LIBs developed by Sony in 1991, but still, there are some challenges associated with LIBs that need to be solved for achieving high power density and efficient performances at high and low temperatures. Safety, cost, and enhancement in energy and power densities are the major concerns in next generation LIBs. [10][11][12] Separator is one of the important components of LIBs that is not directly involved in the electrochemical reaction, however, its properties, structure, and composition greatly influence the performance of batteries with respect to internal resistance, long cycle performances, high capacity, and safety. [13] The basic functions of the separator are to prevent the contact between anode and cathode to avoid internal short circuits, store liquid electrolyte, and permit the migration of ions during the chargedischarge process. [14][15][16] The ideal separator should possess Lithium-ion batteries (LIBs) are promising energy storage devices for integrating renewable resources and high power applications, owing to their high energy density, light weight, high flexibility, slow self-discharge rate, high rate charging capability, and long battery life. LIBs work efficiently at ambient temperatures, however, at high-temperatures, they cause serious issues due to the thermal fluctuation inside batteries during operation. The separator is a key component of batteries and is crucial for the sustainability of LIBs at high-temperatures. Th...

“…could be attained in one separator membrane. PVDF/poly(m-phenylene isophthalamide) (PMIA) [ 135 ], PVDF/polyethylene terephthalate (PET) [ 136 ], PVDF/PI [ 137 ], and polysulfonamide (PSA)/PET [ 138 ] are some of the reported multilayer electrospun separators. Post-treatment of the electrospun fibrous membranes is a great technique for modification and improvement of various characteristics.…”

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.
