Graphene, an sp2 hybridized single sheet of carbon atoms organized in a honeycomb lattice, is a zero band gap semiconductor or semimetal. This emerging material has been the subject of recent intensive research due to the novelty of its structural, electronic, optical, mechanical, and magnetic properties. Due to these properties, graphene is a favorable material for the fabrication of electronic devices, transparent electrodes, spintronics devices, and a growing array of several other applications that explore the potential of this marvelous material. However, the lack of intrinsic band gap and nonmagnetic nature of graphene limit its practical applications in the widely expanding field of carbon-based devices. To take advantage of the hidden potential of this material, numerous techniques have been developed to tailor its electronic and magnetic properties. These methods include the mutual interaction between graphene layer and its substrate, doping with surface adatoms, substitutional doping, vacancy creation, and edges and strain manipulation. Herein, an overview of recently emerging innovative techniques adopted to tailor the electronic and magnetic properties of graphene is presented. The limitations, possible directions for future research and applications in diverse fields of these methods are also mentionedpublishersversionPeer reviewe

“…Other kinds of graphene also proved their strength upon long term cycling. Indeed, N-doped RGO, [ 95 ] porous RGO aerogel, [ 96 ] N-doped 3D macroporous RGO, [ 97 ] N-doped graphene (synthesized by bottom-up procedure), [ 98 ] N-S-codoped RGO, [ 99 ] N-F-codoped RGO, [ 100 ] N-doped holey RGO foam, [ 101 ] and porous graphene (obtained by a peculiar top-down process) [ 102 ] displayed some of the most promising electrochemical performances among all graphene-based anodes (Table 1 ). Interestingly, it was also proved that multilayer graphene (obtained by liquid-phase exfoliation in 1-ethyl-3-methylimidazolium acetate ionic liquid) could reversibly store lithium ions down to −30 °C, showing noticeable specifi c gravimetric capacity even when directly compared to its graphite analogue.…”

Critical Insight into the Relentless Progression Toward Graphene and Graphene‐Containing Materials for Lithium‐Ion Battery Anodes

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...

“…As an advanced energy storage and conversion system, lithium‐ion batteries (LIBs) have achieved huge success in many fields in the last few decades, especially for portable electronic devices and electrical vehicles ,. However, the limited energy density and poor cycle life hinder their wilder application, thus the design and exploration of suitable electrode materials and architecture play a key role in improving the battery performance ,. It is widely accepted that traditional commercial graphitic carbon anode materials are unbefitting to meet the ever‐growing demands for high energy density LIBs due to their related low specific capability (372 mA h g −1 ) and limited rate capability …”

Developing high-energy-density lithium-ion batteries (LIBs) is of great significance for their wider commercialized application. The design of self-integrated electrodes can be treated as a valid approach to achieve this goal. In this work, a facile and low-cost wet chemical oxidation strategy is put forward to prepare self-integrated porous leaf-like CuO nanoplates on Cu foil substrates in situ. These nanoplates are then directly used as the anode for LIBs. The morphology, structure, and composition of the resultant CuO/Cu hybrid foils are characterized, and the relevant lithium storage properties of this anode are also investigated by using standard electrochemical tests. The results show that the CuO/Cu hybrid-based anode possesses a porous leaf-like morphology and self-integrated architecture. Benefitting from this unique morphology and favorable architecture, the CuO/Cu hybrid-based anode exhibits outstanding electrochemical performance, including excellent cycling stability and remarkable rate capability, demonstrating great potential in the application of high-energy-density LIBs.
