“…Unfortunately, none of these enabled satisfactory long term stability (maximum 100 cycles), and most of them showed a high 1 st cycle irreversible capacity (see Table 2 ). At the same time, previously reported graphene-containing alloy (e.g., Sn, [ 144 ] SnO 2 [145][146][147][148][149] or Si [150][151][152][153] ), conversion (e.g., Fe 3 O 4 , [154][155][156][157] Co 3 O 4 [158][159][160][161] or CuO [162][163][164] ) and insertion (e.g., TiO 2 [165][166][167][168] or LTO [169][170][171] ) hybrids were further improved. Interestingly, some appealing approaches, such as the use of ternary hybrids (e.g., RGO/SnO 2 /Fe 3 O 4 [ 172 ] or RGO/CNT/ Sn [ 173 ] ), porous 3D (e.g., RGO/Fe 3 O 4 [ 174,175 ] ) and hollow architectures (e.g., RGO/Fe 3 O 4 [ 176 ] and RGO/TiO 2 [ 168 ] ), were introduced.…”

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...

“…Graphene nanosheets have high conductivity, large area, and a rich porous texture, which makes the material fl exible and able to be used as a confi ning structure with substantial buffering capability to reduce electrode pulverization. Mn 3 O 4 -graphene, [ 23 ] Co 3 O 4 -graphene [ 24 ] and Fe 3 O 4 /graphene [25][26][27] anode materials have been studied for LIBs, and all of them showed positive effects. For the Fe 3 O 4 /graphene systems, [ 28 , 29 ] the results showed that the effect of the structure of graphene on the LIBs properties is remarkable, and it is possible to improve it by changing the structures and shapes of the composites.…”

Self‐Assembly and Embedding of Nanoparticles by In Situ Reduced Graphene for Preparation of a 3D Graphene/Nanoparticle Aerogel

et al. 2011

A 3D graphene architecture can be prepared via an in situ self-assembly of graphene prepared by a mild chemical reduction. Fe(3) O(4) nanoparticles are homogeneously dispersed into graphene oxide (GO) aqueous suspension and a 3D magnetic graphene/Fe(3) O(4) aerogel is prepared during the reduction of GO to graphene. This provides a general method to prepare 3D graphene/nanoparticle composites for a wide range of applications including catalysis and energy conversion.

“…Due to the poor electronic conductivity of Co3O4, various attempts have been made to improve the stable capacities and rate performance of Co3O4 anodes [199], including the addition of highly conducting additives such as graphene [199][200][201][202][203] and silver nanoparticles [204]. For example, Co3O4 nanoparticles (10-30 nm), anchored on graphene sheets displayed a considerably improved rate performance compared to bare Co3O4 samples at the same rate (Fig.…”

Evaluating the performance of nanostructured materials as lithium-ion battery electrodes

Access to the full text of the published version may require a subscription. Rights © Tsinghua University Press and Springer-Verlag Berlin ABSTRACTThe performance of the lithium-ion cell is heavily dependent on the ability of the host electrodes to accommodate and release Li + ions from the local structure. While the choice of electrode materials may define parameters such as cell potential and capacity, the process of intercalation may be physically limited by the rate of solid-state Li + diffusion. Increased diffusion rates in lithium-ion electrodes may be achieved through a reduction in the diffusion path, accomplished by a scaling of the respective electrode dimensions.In addition, some electrodes may undergo large volume changes associated with charging and discharging, the strain of which, may be better accommodated through nanostructuring. Failure of the host to accommodate such volume changes may lead to pulverisation of the local structure and a rapid loss of capacity. In this review article, we seek to highlight a number of significant gains in the development of nanostructured lithium-ion battery architectures (both anode and cathode), as drivers of potential next-generation electrochemical energy storage devices.
