“…They regained a high discharge capacity a current density of 0.1 C. In addition, the coulombic efficiency at a different rate was maintained at 100% except during the first cycle. The CV curves of the NCA fibers in figure 3(d) show a pair of obvious redox peaks that corresponded to the redox couple of Ni 2+ /Ni 4+ [18]. It is clearly shown that the major anodic peak shifted from 3.930 V at the first cycle to 3.871 V and 3.841 V at the second and third cycle, respectively.…”

A ropelike LiNi 0.8 Co 0.15 Al 0.05 O 2 (NCA) fiber with superior rate capability and cycling stability was successfully synthesized via electrospinning and sintering as a cathode material for Li-ion batteries. The NCA fiber that exhibited excellent electrochemical performance as a cathode for Li-ion batteries was stacked and assembled from numerous nanoparticles. The NCA fiber delivered a high reversible capacity of 206.4 mAh g −1 at 0.1 C, and maintained 75% capacity retention after 100 cycles at 1 C. The high rate capability and outstanding cyclic stability were due to the ropelike fiber structure that shorten the Li + diffusion path, improved the Li + diffusion coefficient, and maintained the fiber structure during cycling.

High energy Li‐ion batteries (LIBs) have garnered substantial consideration in recent years for their utilization in many fields like communication, transportation, and aviation. As the cathode is the crucial component of LIBs, so by enhancing its electrochemical performance, the capacity, rate capability, as well as cyclability of batteries can be enhanced. Ni‐rich cathode materials (LiNi x Mn y Co1−x−y O2, x ≥ 0.5) have been accredited for their benefits in enhanced capacity, high working voltage, and low manufacturing cost. The high Ni content is accountable for the exceptional capacity but the utilization in the commercialized LIBs is mired by their electrochemical cycling issues like capacity fading, voltage decay, and safety hazard. To overcome these obstructions, a variety of methodologies have been adopted like doping, coating, and comodification of these cathode materials. An inclusive study of Ni‐rich cathode materials, their degradation mechanism, and the strategies is conferred, which have been employed in recent years to overcome the challenges faced by these materials in their commercialization.
