Single atoms are attracting much attention in the field of energy conversion and storage due to their maximal atomic utilization, high efficiency, and good selectivity. Moreover, their unique electronic structure could improve the intrinsic activity of the active sites. However, the high surface free energy of single atoms inevitably results in their serious aggregation, leading to degraded catalytic activity and poor cycling life. To solve these issues, supports with high surface areas have to be developed to reduce loading density of single atoms and further decrease the surface free energy. Furthermore, engineering the active sites of these substrates can also regulate chemical coordination of single atoms, enhancing their catalytic performance. Owing to high surface area, excellent conductivity and adjustable surface properties, graphene is widely utilized to load atomic metal catalysts. In this review, the fabrication strategies and characterization methods of single atoms on graphene (SAG) are summarized first. Subsequently, the electrochemical applications of SAG on the oxygen reduction reaction, oxygen evolution reaction, hydrogen evolution reaction, carbon dioxide reduction, and methane oxidation are discussed in detail. Finally, the future developments and prospects in fabrication and application of SAG are also discussed.

In spite of an ongoing advancement, current popular EES systems including Li-ion batteries (LIBs), supercapacitors (SCs), and redox flow cells (RFCs) are limited by severe performance challenges of electrode materials in terms of low energy and power density as well as short durability. To mitigate the issues, carbon nanomaterials could be introduced to these EES systems, taking advantage of their unique geometry, excellent conductivity, large surface area, and intrinsic flexibility. Numerous carbon nanomaterial based EES systems, where carbon nanomaterials are adopted as either conducting additive or active electrode, have been developed and demonstrated appealing energy and power features. With the capability to enhance the structural and electrochemical properties of electrodes, carbon nanomaterials and their derivatives offer a wide range of possibilities to design advanced EES devices that can meet our growing energy and power demands in the future.A number of reviews have been published in the past few years on the application of carbon nanomaterials in EES. [5][6][7][8] However, this area is so active and new works accumulate very quickly. Therefore, it is helpful to update the new designs and outcomes. This progress report will summarize the most exciting recent (from the year 2010 onwards) advances in the application of carbon nanomaterials with different dimensions, i.e., 0D fullerene, 1D CNT, 2D graphene, and 3D assemblies of CNT and graphene, in EES systems, and highlight the new trends in the field. Besides the repetitively reviewed LIBs and SCs, this work will also deal with another important system, the RFC, which has been rejuvenated recently and is becoming increasingly vital for large scale energy storage. The recent EES applications of carbon nanomaterials will be discussed based on their dimensions. Structure and Properties of Various Nanostructured CarbonFullerenes, CNTs, and graphene all present conjugated π electron systems.

Renewable energy has attracted growing attention due to energy crisis and environmental concern. The renewable power is featured by its intermittent and fluctuating nature, which requires large-scale electrical energy storage devices for dispatch and integration. Among the current energy storage technologies (e.g., pumped hydro, flywheel, compressed air, superconducting magnet, electrochemical systems), electrochemical storage technologies or batteries that reversely convert electrical energy into chemical energy demonstrate extremely great potential in the stationary and transportation applications. Scale determines the device type. Redox flow batteries (RFBs), as one of the large-scale types, are capable of complying with power station. Meanwhile, portable smart electronic devices promote the development of small-scale energy storage systems, such as Li-ion batteries and supercapacitors. With delicate device configuration, materials play critical roles on pursuing advancing performance, in terms of electrode, current collector, and separator. Carbon nanotube (CNT)/polymer composites exhibit promising potentials in the above key entities, which integrate the merits of conductivity, mechanical strength, flexibility, and cost. Therefore, this chapter is devoted to the design and application of carbon nanotube/polymer composites in different kinds of energy storage systems.
