“…Electrospinning of a solution of nickel acetate and PAN in DMF, followed by stabilization and carbonization, generated nickel-embedded carbon fibers. 55 The specific capacitance of the carbon fiber electrode without the Ni loading was only 50 F/g, while the value for 22.4 wt% Ni/carbon electrode increased to 164 F/g. This increase was ascribed to the electrochemical catalysis effect of Incorporation of redox-active species into electrospun carbon fibers can improve significantly their electrochemical capacitance due to the simultaneous use of both charge storage mechanisms (i.e., electrical double layer and redox reactions).…”

Abstract:The applications of electrospun carbon fiber webs to the development of energy storages devices, including both supercapacitors and lithium ion batteries (LIB), are reviewed.Following a brief discussion of the fabrication process and characterization methods for ultrafine electrospun carbon fibers, recent advances in their performance as supercapacitors and LIBs anode materials are summarized. Optimization of the overall electrochemical properties of these materials through choice of thermal treatment conditions, incorporation of additional active components (such as carbon nanotubes, metal oxides, and catalysts), and generation of novel fibrous structures (such as core-shell, multi-channel or porous fibers) is highlighted. Further challenges related to improving the conductivity, surface area, and mechanical properties of the carbon nanofiber webs, as well as the scale-up ability of the fabrication technique, are discussed.

Electrospinning of nanomaterial composites are gaining increased interest in the fabrication of electronic components and devices. Performance improvement of electrospun components results from the unique properties associated with nanometer-scaled features, high specific surface areas, and light-weight designs. Electrospun nanofiber membrane-containing polymer electrolytes show improved ionic conductivity, electrochemical stability, low interfacial resistance, and improved charge-discharge performance than those prepared from conventional membranes. Batteries with non-woven electrospun separators have increased cycle life and higher rate capabilities than ones with conventional separators. Electrospun nanofibers may also be used as working electrodes in lithium-ion batteries, where they exhibit excellent rate capability, high reversible capacity, and good cycling performance. Moreover, the high surface area of electrospun activated carbon nanofibers improves supercapacitor energy density. Similarly, nanowires having quasi-one-dimensional structures prepared by electrospinning show high conductivity and have been used in ultra-sensitive chemical sensors, optoelectronics, and catalysts. Electrospun conductive polymers can also perform as flexible electrodes. Finally, the thin, porous structure of electrospun nanofibers provides for the high strain and fast response required for improved actuator performance. The current review examines recent advances in the application of electrospinning in fabricating electronic components and devices.

“…Nevertheless, a major drawback of MnO 2 is its poor electrical conductivity, which limits its power-delivery capability. An effective approach to overcome this disadvantage is the introduction of electronically conductive materials, such as graphite [8], carbon nanofibers [9] and CNTs [3,[10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. Among them, CNTs have been intensively investigated for their excellent conductivity, large intrinsic area, and chemical stability.…”
