What are the applications of 3D graphene in energy storage?

This Account focuses on energy storage applications, including supercapacitors, Zn-based hybrid capacitors, and the use of 3D graphene in the cathodes and anodes of Zn-ion batteries. In energy conversion, we emphasize its role in water splitting, dye-sensitized solar cells (DSSCs), and solar desalination.

What is a graphene battery?

Graphene batteries represent a revolutionary advancement in energy storage technology, promising to overcome the limitations of traditional lithium-ion batteries. The evolution of graphene batteries can be traced back to the discovery of graphene in 2004, which sparked intense research into its potential applications.

Why is 3D graphene a good cathode material?

3D graphene has emerged as a highly effective cathode material in energy storage systems due to its outstanding electrical conductivity, large surface area, and structural flexibility. These characteristics enhance charge transport, boost energy storage capacity, and improve mechanical stability while preventing the restacking of graphene layers.

Could graphene batteries improve energy storage for solar and wind systems?

Graphene batteries could improve energy storage for solar and wind systems. Their high performance helps store intermittent energy more effectively, which supports the transition to renewable power sources and reduces fossil fuel dependence.

Does graphene outperform PT in DSSCs?

(52) This graphene material outperformed Pt in DSSCs, achieving a 10.1% energy conversion efficiency compared to Pt’s 7.7% (Figure 4 c). The use of CO 2 as a precursor also presents an eco-friendly solution, turning emissions into valuable materials for solar energy conversion.

What are 3D graphene networks?

Supports like 3D graphene networks address aggregation issues, improving dispersity and recyclability. 3D graphene networks offer unique properties, such as low mass density, large light absorption, and porous surface areas, making them promising for solar energy harnessing applications. (3−5)
