“…The maximum N 2 adsorption capacity of the membrane was 412.23 cm 3 /gm. The values are significantly larger than the fiber membrane reportedly produced using the MOF particles synthesized by solvothermal method [32]. A comparative BET analysis between the two differently produced membranes is given in Fig.…”

“…Therefore, further emphasis should be given on generating an applicable and cost-effective method of fabricating nanofibrous CO 2 adsorption membrane. Our previous approach to produce a MOF-loaded adsorption membrane consists of electrospun PAN (polyacrylonitrile) membrane loaded with MOF particles of 3–6 μm in size [32]. HKUST-1 was selected as MOF because of its excellent adsorption performance and compatibility with PAN.…”

We report the sonochemical synthesis of MOF (metal organic framework) nanoparticles of 30–200 nm in size and electrospraying of those particles on electrospun nanofibers to process a MOF-attached nanofibrous membrane. This membrane displayed significant selectivity towards CO2 and capacity of adsorbing with 4000–5000 ppm difference from a mixed gas flow of 1% CO2 and 99% N2. Applying ultrasonic waves during the MOF synthesis offered rapid dispersion and formation of crystalline MOF nanoparticles in room temperature. The MOF nanoparticles of 100–200 nm in size displayed higher surface area and adsorption capacity comparing to that of 30–60 nm in size. Nanofibrous membrane was produced by electrospinning of MOF blended PAN solution followed by electrospraying of additional MOF nanoparticles. This yielded uniform MOF deposition on nanofibers, occurred due to electrostatic attraction between highly charged nanoparticles and conductive nanofibers. A test bench for real-time CO2 adsorption at room temperature was built with non-dispersive Infrared (NDIR) CO2 sensors. Comparative tests were performed on the membrane to investigate its enhanced adsorption capacity. Three layers of the as-produced membranes displayed CO2 adsorption for approximately 2 h. Thermogravimetric analysis (TGA) of the membrane showed the thermal stability of the MOF and PAN up to 290 and 425 °C, respectively.

Lithium-sulfur (Li-S) batteries are in the spotlight because their outstanding theoretical specific energy is much higher than those of the commercial lithium ion (Li-ion) batteries. Li-S batteries are tough competitors for futuredeveloping energy storage in the fields of portable electronics and electric vehicles. However, the severe "shuttle effect" of the polysulfides and the serious damage of lithium dendrites are main factors blocking commercial production of Li-S batteries. Owing to their superior nanostructure, electrospun nanofiber materials commonly show some unique characteristics that can simultaneously resolve these issues. So far, various novel cathodes, separators, and interlayers of electrospun nanofiber materials which are applied to resolve these challenges are researched. This review presents the fundamental research and technological development of multifarious electrospun nanofiber materials for Li-S cells, including their processing methods, structures, morphology engineering, and electrochemical performance. Not only does the review article contain a summary of electrospun nanofiber materials in Li-S batteries but also a proposal for designing electrospun nanofiber materials for Li-S cells. These systematic discussions and proposed directions can enlighten thoughts and offer ways in the reasonable design of electrospun nanofiber materials for excellent Li-S batteries in the near future.or conducting coagulation bath) is placed against the capillary. A thin polymer fiber membrane is deposited on the collector. The electrospun nanofibers have big potential for developing the outstanding energy storage systems due to their high surface area and excellent surface-to-volume ratio which can offer numerous active sites and controllable porous structure to buffer the huge volume changes during battery cycling and infiltrate the electrolyte. [18] Electrospun nanofiber membranes possess high porosity, large specific surface area, and controllable pore size, which will block "shuttle effect" of polysulfides and enhance the wettability for electrolytes. [19] Electrospinning technique and carbonization process are facile to manufacture freestanding nanofiber fabrics with controllable porous architecture and outstanding electrical conductivity. Electrospun porous nanofibers can come into a reservoir-like matrix for the reserve of active materials. First, the hierarchical pores in electrospun porous nanofibers can improve the reactive S reaction sites and block soluble polysulfides, thereby decreasing the "shuttling effect" of polysulfides during the electrochemical cycling. Second, electrospun porous fibers have excellent physical and mechanical properties, outstanding architecture, and superior electrical conductivity, which can enhance the transfer of Li-ions and electrons, endowing extraordinary electrochemical performance of the whole battery system. [20] Figure 2 shows phase and morphological evolutions of the electrospun nanofibers. By combining the electrospinning and other treatment (thermal, chem...

Electrospinning is a popular technique to prepare 1D tubular/fibrous nanomaterials that assemble into 2D/3D architectures. When combined with other material processing techniques such as chemical vapor deposition and hydrothermal treatment, electrospinning enables powerful synthesis strategies that can tailor structural and compositional features of energy storage materials. Herein, a simple description is given of the basic electrospinning technique and its combination with other synthetic approaches. Then its employment in the preparation of frameworks and scaffolds with various functions is introduced, e.g., a graphitic tubular network to enhance the electronic conductivity and structural integrity of the electrodes. Current developments in 3D scaffold structures as a host for Li metal anodes, sulfur cathodes, membrane separators, or as a 3D matrix for polymeric solid‐state electrolytes for rechargeable batteries are presented. The use of 1D electrospun nanomaterials as a nanoreactor for in situ transmission electron microscopy (TEM) observations of the mechanisms of materials synthesis and electrochemical reactions is summarized, which has gained popularity due to easy mechanical manipulation, electron transparency, electronic conductivity, and the easy prepositioning of complex chemical ingredients by liquid‐solution processing. Finally, an outlook on industrial production and future challenges for energy storage materials is given.
