“…The remarkable improvement in the cycle performance of SiO 2 /Al 2 O 3 (1:1)-coated PI membranes was probably due to the favorable interface characteristic as well as strong affinity of SiO 2 /Al 2 O 3 (1:1)-coated PI membranes and the liquid electrolyte. Besides, SiO 2 and Al 2 O 3 could capture the acidic electrolyte magazines and trace amounts water of electrolyte, and reduce the capacity attenuation of battery [24][25][26]. The presence of SiO 2 reduced the impedance interface, the existence of Al 2 O 3 increased the ionic conductivity.…”

“…The straight slopping line corresponds to the diffusion of lithium ion in the active material of electrode. 66 Figure 12a clearly depicted that the charge-transfer resistance of the cell using PSA@PVDF-HFP composite nonwoven at first cycle was 14 , which slightly lower to that of PP separator (16 ). However, obvious differences of the charge transfer regime at the 50th cycle were observed in Figure 12b.…”

A core-shell structured polysulfonamide@polyvinylidene fluoride-co-hexafluoropropene composite nonwoven separator was exploited for lithium ion battery via coaxial electrospinning technique for enhanced safety characteristic of battery. Polysulfonamide (PSA) and polyvinylidene fluoride-co-hexafluoropropene (PVDF-HFP) were used as the inner (core) and outer (shell) layer, respectively. Compared with the commercial polypropylene (PP) separator, the PSA@PVDF-HFP composite nonwoven separator manifested higher porosity, better electrolyte wettability and superior thermal stability. Moreover, it was demonstrated that the assembled cell with PSA@PVDF-HFP composite nonwoven separator displayed superior rate capability and better cycling capacity retention than those of PP separator. Notably, these attractive characteristics would endow PSA@PVDF-HFP composite nonwoven a promising separator for high power lithium ion battery.Lithium ion battery has been widely expanded into some newly promising fields such as portable electronic equipment and hybrid electric vehicles because it could offer high energy density and high power density. 1-6 The lithium ion battery separator plays an important role in preventing internal electrical short circuit, and at the same time allowing fast lithium ion transport between cathode and anode. 7-9 Commercially available polyolefin-based separators (polyethylene (PE) and polypropylene (PP) separators) possessed several advantages, such as thermal shut-down property, good electrochemical stability and proper mechanical strength. 7,10 Nevertheless, these polyolefin-based separators suffered from low porosity, poor electrolyte wettability and severe thermal shrinkage at elevated temperature. 10-13 The poor electrolyte wettability impaired the rate capability and cycling stability of the battery, and brought a series of disadvantages in the manufacturing process. The severe thermal shrinkage of polyolefin-based separator would cause serious internal electrical short circuit, thus finally led to fire disaster or explosion when the cells were exposed to abnormal conditions. 14 Therefore tremendous efforts have been made to develop high performance separators with enhanced electrochemical properties and better safety charateristics. 15,16 Electrospinning has been developed as a simple and versatile technique to fabricate polymeric nanofibrous nonwovens. [17][18][19][20] Polymeric nanofibrous nonwovens such as polyacrylonitrile (PAN), polyvinylidene fluoride (PVDF) and polyimide (PI) were shown to possess high porosity, good electrolyte wettability and enhanced ionic conductivity. [21][22][23][24] In recent years, several works about composite nanofiber-based membranes have been reported as lithium ion battery separator. 25-28 Electrospun PVDF-based membranes exhibited a threedimensional network structure, higher porosity, better electrolyte uptake, high ionic conductivity and adequate mechanical properties and enhanced electrochemical properties due to the interaction between the PVDF chain and the a...

“…After immersion, the membrane is taken out of the electrolyte solution and the excess electrolyte solution on the surface of the separator is wiped off with filter paper. The uptake of electrolyte solution is determined using the following equation [86,132];

U p t a k e false(% false) = \frac{W - W_{0}}{W_{0}} \times 100

where W 0 and W are the weights of the electrospun mat before and after soaking in the liquid electrolyte, respectively.…”

Ceramic nanofibers (NFs) have recently been developed for advanced applications due to their unique properties. In this article, we review developments in electrospun ceramic NFs with regard to their fabrication process, properties, and applications. We find that surface activity of electrospun ceramic NFs is improved by post pyrolysis, hydrothermal, and carbothermal processes. Also, when combined with another surface modification methods, electrospun ceramic NFs result in the advancement of properties and widening of the application domains. With the decrease in diameter and length of a fiber, many properties of fibrous materials are modified; characteristics of such ceramic NFs are different from their wide and long (bulk) counterparts. In this article, electrospun ceramic NFs are reviewed with an emphasis on their applications as catalysts, membranes, sensors, biomaterials, fuel cells, batteries, supercapacitors, energy harvesting systems, electric and magnetic parts, conductive wires, and wearable electronic textiles. Furthermore, properties of ceramic nanofibers, which enable the above applications, and techniques to characterize them are briefly outlined.
