One-Dimensional Nickel Molybdate Nanostructures with Enhanced Supercapacitor Performance

One-dimensional NiMoO4 nanofibers were successfully prepared by electrospinning and high-temperature calcination. The supercapacitor performance tests were conducted on the prepared materials in a three-electrode system, and it was found that the calcination temperature during the preparation of the fibers seriously affects the final morphology and electrochemical performance of the obtained samples. The sample with a calcination temperature of 500 degrees C has better performance, its specific capacitance can reach 1947 F g(-1), and the retention rate is 82.35% after 3000 cycles of constant current charging-discharging. The improvement of electrochemical performance is primarily on account of the unique one-dimensional nanostructure of the material, which can both enhance the charge transfer efficiency and effectively increase the speed of electrolyte ion diffusion.

Automated summary

One-dimensional NiMoO4 nanofibers were successfully prepared and tested in a three-electrode system. The calcination temperature during preparation significantly affected the morphology and electrochemical performance. The sample calcinated at 500 degrees C showed better performance with higher specific capacitance and retention rate. The improved electrochemical performance can be attributed to the unique one-dimensional nanostructure, which enhances charge transfer efficiency and electrolyte ion diffusion speed.
