Electrospinning is an intensely facile methodology for the precise manufacturing of polymer nanofibers by manipulation of electrostatic force, which stunts like a driving force. In this technique, fibers produced with a diameter range between 50 to 500 nm. Two practices are made up by the scientists for electrospinning of versatile polymer. Polymers can be electrospun into ultrafine fibers in solvent solution or melt form. Tremendous progress had been made in this field in the past, and numerous applications were inaugurated. It’s a field of nanotechnology which rapidly growing due to enormous potential in creating novel applications regarding morphologies, materials structure, surface area, porosity, and Reinforcement in nanocomposite development. Fibers can be assembled in the form of nonwoven, aligned, patterned, random three-dimensional structures and sub-micron fibers. Many complications faced during electrospinning, for example, control the morphology and structure of Nanofibers, analyze surface functionality, and assembling strategies for various polymers. We need to find out various parameters for accurate fiber assembly. Here we briefly review the evolution activities in the field of electrospinning, understand its process, polymeric structure, property characterization, technology frailty, research provocations, future expectations, and resourceful applications.

This study is conducted to explore the best electrodes materials for energy conversion devices. The two cathode materials (LiMn2O4 and nanofibers of LiMn2O4) and the anode material (graphene/polyaniline/carbon-nanotube) were synthesized by a wet chemical method which includes sol-gel and chemical polymerization techniques. The prepared materials were characterized by SEM, XRD FTIR, and cyclic voltammetry. The characterization results show that LiMn2O4 exhibits a porous and hollow structure, which improves the utilization of the active mass area, and allows the dual conduction of Li+ and electrons, which effectively relieves the structural strain and volume change. The cyclic voltammetry results record that LiMn2O4 and nanofibers of LiMn2O4 as a cathode material enhanced the cycling performance and possess excellent stability. Further, the conductivity of each sample was measured using the DC four-probe method, and the highest conductivity was observed for the LiMn2O4 nanofibers 1.43 SCm-1 at 650℃.
