“…As lithium is inherently unstable, composite cathodes are preferred over pristine lithium, as they offer high stability, a broad potential window, and adjustable redox potentials. Commonly used cathode materials include vanadium oxides, tri chalcogenides, iron compounds made up of oxides and phosphates, and transition metal oxides [ 36 ]. The choice of materials for synthesis must be wise since it affects how well the battery works.…”

Electronic devices commonly use rechargeable Li-ion batteries due to their potency, manufacturing effectiveness, and affordability. Electrospinning technology offers nanofibers with improved mechanical strength, quick ion transport, and ease of production, which makes it an attractive alternative to traditional methods. This review covers recent morphology-varied nanofibers and examines emerging nanofiber manufacturing methods and materials for battery tech advancement. The electrospinning technique can be used to generate nanofibers for battery separators, the electrodes with the advent of flame-resistant core-shell nanofibers. This review also identifies potential applications for recycled waste and biomass materials to increase the sustainability of the electrospinning process. Overall, this review provides insights into current developments in electrospinning for batteries and highlights the commercialization potential of the field.

“…The presence of non-uniform electrode microstructures directly impacts ionic transport and, consequently, influences the cell's overall performance [6,[51][52][53][54]. To illustrate the effects of non-uniform cathode particle configurations, the polarization curve is depicted in Figure 6, considering slow, fast, and ultrafast current densities.…”

The Li-ion battery's diverse applications necessitate the quest to design energy and powerdense electrode microstructure. The present study uses the Doyle-Newman framework to probe the interplay of cathode particle size configurations for various current densities. Our study reveals the interplay of cathode particle size distribution and C-rate on cell performance characteristics. Further, the cell performs better when the cathode employs a cathode particle size configuration arranged non-uniformly. Moreover, the cell characteristics, viz. specific energy, specific power, and capacity, are highest for the configuration where the cathode particle size increases in the direction of the cathode current collector interface. Additionally, losses are relatively lesser in this configuration. Furthermore, the cell characteristics become more significant for higher current density. In addition, as particle size grows at a higher rate, the improvement in cell performance is significant. Our findings bear utility towards advancement in cathode on the microstructural scale and offer better spatiotemporal ionic transport kinetics.

“…Lithium-Ion Battery (LIB) is composed of four main parts, which are the negative electrode (anode), positive electrode (cathode), electrolyte, and separator [10]. The cathode in a lithium-ion battery is an important component because it affects the charging and discharging process when there is an exchange of Li + ions which will determine battery performance [11]. Lithium Nickel Manganese Cobalt Oxide (LiNi x Mn y Co z O 2 or NMC) is one of the most commonly used cathode materials in lithium-ion batteries [12].…”

The need for energy in various activities around the world is increasing. Batteries come as an important energy solution, among others, for various applications, such as electric vehicles, mass storage for utilities, gadgets, etc. Lithium-ion batteries that are able to produce superior performance are needed. The battery cathode is an important key to the performance of lithium-ion batteries. The battery cathode fabrication factor is one that affects the quality of the battery produced. The thickness of the coating material will determine the amount of active material contained in the cathode, while the calendering process is needed to compress the material in the cathode so that the lithium-ion transfer process in the battery can run more effectively. Based on the research results, the thicker the coating material on the cathode, the greater the capacity value produced. With a coating thickness of 300 µm, the resulting capacity reaches 180 mAh/gr. However, in the life cycle and rate capability tests, the performance stability is not better than the thickness of 100 µm and 200 µm. As for the calendering level, the battery with an optimum decrease in dry thickness is able to have the best performance in terms of capacity, life cycle, and rate capability.
