In this review, after a short introduction to graphene and its derivatives, we summarize the recent advances in the synthesis and applications of graphene and its derivatives in the fields of energy storage (lithium ion, lithium–air, lithium–sulphur batteries and supercapacitors) and conversion (oxygen reduction reaction for fuel cells).

Graphene-based nanocomposites have been proven to be suitable for the development of basic materials for alternative energy sources in energy devices. In lithium-ion batteries, graphene endows the battery with high-power density, high energy density, and fast charging speed.
Can graphene-based composites be used for energy storage?
While graphene-based composites demonstrate great potential for energy–storage devices, several challenges need to be addressed before their practical application in various fields.
Can graphene improve battery performance?
Within energy storage sector, especially in battery technology, graphene shows promise for improving battery component performance. Graphene/silicon composites in lithium-ion batteries are gaining attention for their potential to overcome some of the challenges associated with silicon as a high-capacity anode material.
Can graphene improve energy storage performance?
Graphene, a remarkable two-dimensional (2D) material, holds immense potential for improving energy–storage performance owing to its exceptional properties, such as a large-specific surface area, remarkable thermal conductivity, excellent mechanical strength, and high-electronic mobility.
What is graphene used for?
In this review, after a short introduction to graphene and its derivatives, we summarize the recent advances in the synthesis and applications of graphene and its derivatives in the fields of energy storage (lithium ion, lithium–air, lithium–sulphur batteries and supercapacitors) and conversion (oxygen reduction reaction for fuel cells).
These results indicate that the advanced LFP@C/S-doped graphene composite was an excellent cathode material for lithium energy storage. Liu et al. successfully prepared LFP/graphene composites as cathode materials by one-step microwave heating method.
