“…Unfortunately, the authors erroneously calculated the energy and power on a single electrode basis. Other materials such as bottom-up-synthesized graphene, [ 85 ] electrochemically exfoliated graphene, [ 86 ] holey-RGO hydrogel, [ 87 ] CVD-derived fl exible graphene paper, [ 88 ] polysulfi de-functionalized RGO [ 89 ] and catalytically exfoliated few-layer graphene [ 90 ] were characterized and tested. Unluckily, despite the valuable cycling performances observed in two cases, [ 89,90 ] none of them seemed to have the potential of meeting the requirements of practical use.…”

that its extraordinary properties would enable revolutionary new technologies, which gave birth to the "graphene era". [ 3,4 ] Relying on this scenario, in 2013, the European Union launched the ¤1 billion "Graphene Flagship" project aimed to investigate the properties of this new form of carbon for various applications (e.g., electronics, sensors and energy storage devices), with the ambitious goal of guiding graphene from laboratories to commercial applications within a decade. [ 5,6 ] In the same period, the Chinese Government set up a similar investment to mass-produce graphene as thin fi lms (e.g., for touchscreen electrodes) and platelets (e.g., for use in batteries). [ 6 ] In the following years, hundreds of patents, mainly focused on manufacturing and application in energy storage, were fi led and the worldwide production of graphene and graphene-containing materials rapidly increased. Although a few Chinese industries claimed to already use graphene-containing materials for smartphone production, no revolutionary practical application relying on graphene has been yet developed. [ 6 ] Specifi cally with respect to the battery fi eld, a close analysis of the scientifi c literature reveals a struggle to meet the ambitious initial targets. A potential loss of focus from the fi nal application caused by hype and ease of publication on such a novel matter, together with the delivery of very misleading information [ 7,8 ] and erroneous statements [ 7 ] concerning the use of graphene in batteries are emerging as possible reasons of the ineffective graphene-era outburst. In this progress report, we do not focus on production and classifi cation of graphene and graphene-containing materials, which were already well reported in the past years. [ 3,[9][10][11] In contrast, due to the lack of an exhaustive analysis of the progression of the use of such materials in lithium-ion battery (LIB) anodes, we report here a critical evaluation of the most prominent research papers published from 2008 until the end of 2015. As shown in Figure 1 , three different stages of the graphene research in LIB anodes can be distinguished: a fi rst stationary phase between 2008 and 2010 where the lithium-ion storage properties of different graphene and graphene-containing materials were preliminarily explored, a second exponential stage, spanning from 2010 to 2014, where graphene and graphene-containing anode materials were broadly developed and investigated, and fi nally, a third phase, (i.e., starting from 2015), where the research seems to have approached a plateau. After Used as a bare active material or component in hybrids, graphene has been the subject of numerous studies in recent years. Indeed, from the fi rst report that appeared in late July 2008, almost 1600 papers were published as of the end 2015 that investigated the properties of graphene as an anode material for lithium-ion batteries. Although an impressive amount of data has been collected, a real advance in the fi eld still seems to be missing. In this framework, atten...

“…For example, Cao et al [77] used expanded vermiculite as a layered template in the CVD process to produce bulk materials containing GSs of the order of hundreds of micrometers at a gram scale (Figure 2.14a-c). Owing to the large sheet size, the as-obtained GSs were easily fabricated into flexible graphene papers with low surface density and good conductivity (Figure 2.14d).…”

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.

“…CVD has been developed to fabricate flexible graphene papers with an expanded nanostructure by using expanded vermiculite as the template. The obtained graphene paper exhibited a high reversible capacity (1200 mAh g −1 at 50 mA g −1 ) and an excellent cycling performance as anodes for LIBs because of the increased surface utilization [98]. If the graphene sheets are not tightly stacked, transport channels for Li + will be provided, and the active storage site for Li + will be used efficiently.…”

Carbon is a key component in current electrochemical energy storage (EES) devices and plays a crucial role in the improvement in energy and power densities for the future EES devices. As the simplest carbon and the basic unit of all sp 2 carbons, graphene is widely used in EES devices because of its fascinating and outstanding physicochemical properties; however, when assembled in the macroscale, graphene-derived materials do not demonstrate their excellence as individual sheets mostly because of unavoidable stacking. This review proposal shows to engineer graphene nanosheets from the nano-to the macroscale in a well-designed and controllable way and discusses how the performance of the graphene-derived carbons depends on the individual graphene sheets, nanostructures, and macrotextures. Graphene-derived carbons in EES applications are comprehensively reviewed with three representative devices, supercapacitors, lithium-ion batteries, and lithium-sulfur batteries. The review concludes with a comment on the opportunities and challenges for graphene-derived carbons in the rapidly growing EES research area.
