Graphene Batteries: How to Make a DIY Supercapacitor for Future Energy Solutions
To make a graphene battery, prepare a graphene-based electrode. First, disperse 100 mg of graphene oxide powder in 30 mL of distilled water. Sonicate this mixture for 30 minutes. Important production methods include graphite oxide exfoliation, the Hummers’ method, and epitaxial growth. These techniques help create high-quality graphene materials. To make a supercapacitor, first, prepare … Read more
