Graphene Sheet
Graphene sheet (CAS number 1034343-98-0), also referred to as graphene paper, is the assembly of individual graphene nanosheets into macroscopic structure to form paper-like material. The achieved freestanding graphene sheet shows a unique combination of outstanding properties such as high mechanical strength, large surface area, superior electrical conductivity, and stability in electrochemical environment, outperforming many other carbon substrates.
As a functional material, graphene sheet does not only act as a conducting agent, but also as a current collector. This makes graphene sheet, a promising base flexible electrode material for energy storage devices with significantly improved performances in energy density, power density and better life cycle compared to non-flexible conventional electrode architecture.
