With the growing shortage of fossil energy, environmental pollution is becoming more and more serious, and the development of renewable and clean energy has become the urgent task to solve the global warming and energy crisis. Graphene based nanomaterials have been widely used in the field of new energy conversion and storage due to its unique structure, excellent electrical, thermal and catalytic properties and high specific surface area. In this work, the preparation of nano composite materials based on graphene is introduced, and the electrocatalytic activity and application of the key electrode materials for fuel cell, lithium ion battery and super capacitor, are discussed.
