“…The discharge capacity delivered by the S/N-G composite at a rate of 2.5 C is higher than that of the S/G composite at the cycling rate of 1.5 C. As expected, the S/N-G composite capacity reduces upon increasing the discharge rates. However, S/N-G composite achieves a high reversible discharge capacity of 475 mAh g −1 even at 2.5 C, and the discharge capacity is mostly recovered when the rate is switched back to 0.5 C. The exceptional high-rate performance of the S/N-G composite is attributed to the ability of N-G to act as an electron conductor, and nitrogen doping could allow for the fast electron and ion transfer by decreasing the energy barrier, thus leading to the rate capability enhancement [28]. This suggestion has been confirmed by the following EIS studies.…”

A sulfur/nitrogen-doped graphene (S/N-G) composite was synthesized by simple sonicated mixing of nanosized sulfur suspension and nitrogen-doped graphene suspension followed by heat treatment. Scanning electron microscopy and energy dispersive spectroscopy mapping showed the formation of a porous structure with uniform distribution of sulfur and nitrogen-doped graphene. Electrochemical performance reveals that the resultant S/N-G composite exhibits a high reversible capacity of 1355 mAh g −1 at the initial cycle, with 823 mAh g −1 remaining after 80 cycles at 0.

Graphene-based nanostructures exhibit good mechanical strength, high porosity, outstanding electrical conductivity, and excellent thermal and chemical stability, which in addition to its low cost, versatile functionalization chemistry, and relative ease of large-scale preparation make it ideally suited to serve as a key component for the development of new electrode materials. Recently, a wide variety of methods have been developed for the formation of porous graphene architectures to further improve the performances. Porous graphene provides abundant pathways for rapid ion diffusion and high accessible surface area. In this chapter, the recent continued breakthroughs in the preparation of porous graphene-based nanoarchitectures as well as their applications as electrode materials for electrochemical energy storage devices are introduced.

“…Owing to its better conductivity and uniformity, the Fe 2 O 3 /GN composite exhibited much better electrochemical performance than Fe 2 O 3 /pristine graphene and pure Fe 2 O 3 , achieving a reversible capacity of 1012 mAh g −1 after 100 cycles. In another work, Park et al [61] developed a facile hydrothermal route to grow small Mn 3 O 4 nanoparticles on the surface of N-doped graphene using hydrazine hydrate both as a reducing agent and a nitrogen source. The N-doped graphene/Mn 3 O 4 exhibited a high specific capacity 800 mAh g −1 , which was more stable and higher performance than graphene/Mn 3 O 4 (703 mAh g −1 ).…”

IntroductionAs a kind of carbon material, graphene sheet (GS) has attracted increasing attention in a variety of fields because of its high theoretical specific surface area (2600 m 2 g −1 ), good flexibility, superior chemical/thermal stability, and extraordinary electrical, thermal, and mechanical properties. The unique structure and outstanding properties render graphene highly promising for a wide range of applications in electronics, sensors, and energy storage/conversion.In the field of lithium ion batteries (LIBs), graphene has wide potential windows and rich surface chemistry, and thus can be used as electrode material individually. Also, the high conductivity and unique layered structure make graphene a predominant matrix to form hybrids with other cathode and anode materials. Significant synergistic effects often occur in graphene/other material composites, which will greatly enhance the overall electrochemical performance: On one hand, the conductivity of cathode or anode materials can be significantly increased after compositing with graphene, which will improve the electron transport and rate capability of the electrode; on the other, the good mechanical property of graphene can help maintain the microstructure of electrode materials and improve the cyclic stability. Besides, graphene has an extremely large aspect ratio and excellent structural flexibility; thus it can act as building blocks to self-assemble into two-dimensional (2D) flexible and free-standing electrode as well as three-dimensional (3D) macroscopic aerogels. This is of great importance to promote the development of new electrode structures and new types of LIBs.In this review, we will summarize recent research progress on the synthesis methods, structural design, and electrochemical performance of graphene-based electrodes for high-performance LIBs, including graphene-based cathode materials, graphene-based anode materials, 2D graphene-based flexible electrodes, and 3D macroscopic graphene-based electrodes.Graphene-based Energy Devices, First Edition.
