As capacity requirements in energy storage applications increase, graphene composites such as the embedment/encapsulation of nanostructured materials in graphene have been developed to meet these requirements.
This review provides a comprehensive summary of recent research advancements in the application of graphene for energy–storage. Initially, the fundamental properties of graphene are introduced.
Miscellaneous energy storage devices (solar power) Of further interest and significant importance in the development of clean and renewable energy is the application of graphene in solar power based devices, where photoelectrochemical solar energy conversion plays an important role in generating electrical energy , .
For example, vertically oriented 2D graphene nanosheets possess a smart structure that can be applied in electrochemical energy storage devices. In addition, 3D graphene structures include micro-flowers fabricated through either pure graphene or graphene composites.
Graphene-based nanostructures, as either graphene nanosheets or graphene-based porous nanostructures, can improve the thermal conductivity of phase change materials and shape stability of these energy storage systems significantly.
Here we discuss the most recent applications of graphene — both as an active material and as an inactive component — from lithium-ion batteries and electrochemical capacitors to emerging technologies such as metal–air and magnesium-ion batteries.
