Core-Shell Nanofiber Design:

• Introduces a novel core-shell structure where nanofibers of a second metal oxide (e.g., MnO2) are coated on a Nano fibrous first metal oxide (e.g., ZnO), optimizing energy storage capabilities

Electrospinning Technology:

• Utilizes electrospinning to create Nano fibrous mats, offering a high aspect ratio, large surface area, and ideal morphology for energy storage devices.

Hydrothermal Coating Process:

• Implements a hydrothermal coating method to apply Nano flakes of a second metal oxide onto the first metal oxide nanofibers, enhancing the overall performance of the super capacitor electrodes.

Calcination for Morphological Optimization:

• Involves controlled calcination at 500°C to optimize the granular morphologies of the metal oxide nanofibers, ensuring improved conductivity and efficient charge/discharge cycling.

Asymmetric Super capacitor Configuration:

• Integrates the synthesized core-shell nanofibers as the cathode, paired with a carbonaceous active material as the anode, resulting in an asymmetric super capacitor with high conductivity and aspect ratio.
