RET Teaching Module 23: Rapid Fabrication of a Supercapacitor through intercalation of oxygen in graphite to produce graphene oxide (GO) through a simple and rapid oxidation/reduction reaction with Sulfuric Acid

Overview

The end product built by students in this module will be a supercapacitor. One of the most contemporary and promising energy storage solutions. Through a reduction/oxidation (redox) chemical reaction students will be able to produce a graphene oxide (GO) layer on a dialysis tubing cellulose membrane. The resulting supercapacitor can be tested for its capacitance to demonstrate the increased charge on the membrane. The hands-on activities will allow them to explain how Nanotechnological applications like supercapacitors have led to reduced cost, size, and improved the functionality of integrated circuits.

After completing this module, student should be able to:

• Design, build, and refine a device-supercapacitor- by using the reduction potential of metals and the ability of graphite to form graphene oxide.
• Integrate and evaluate multiple sources of information to design, build and refine their device.
• Communicate their technical findings of capacitance, energy transfer, reduction potentials and how components may store potential energy in an electric field.
