Part 1. What is a graphene battery? Graphene Battery Composition. A graphene battery is an energy storage device that incorporates graphene, a single layer of carbon atoms arranged in a honeycomb lattice structure. Graphene, known for its exceptional electrical conductivity and strength, is a critical component in these batteries.
The graphene sheet is a semi-metal (or a zero-gap semiconductor) because its conduction and valence bands meet at the Dirac points . Graphene can also be modified to generate a band gap (in the range from 0 to 0.25 eV) that can lead to application in the semiconductor industry for developing devices such as transistors.
