“…Lithium-ion batteries (LIBs) are one of the most promising energy storage devices for upcoming largescale applications in EVs due to their high energy density, long lifespan and environmental benignity. To meet the demands of higher energy density and power density, various metal sulfides, including SnS 2 [4][5][6], MoS 2 [7][8][9], CoS [10] and CoS 2 [11][12][13], have been studied as possible candidates to replace carbonaceous anode materials for LIBs. Among them, CoS 2 has attracted great attention, and valuable efforts have been made to demonstrate its potential application as anode material for LIBs due to its very high theoretical capacity of 870 mAh g À1 .…”

“…However, despite some clever approaches to stabilize the structure of the active material (e.g., freeze-drying, [ 206 ] crumpling, [ 207 ] spin coating [ 209 ] or nanocabling [ 211 ] ), only few cases reported a successful minimization of the 1 st cycle irreversible capacity and improved delithiation voltage. [ 220,226 ] In 2013, new types of hybrids, such as graphene-containing metal sulfi des, [229][230][231][232][233][234][235][236] intermetallic compounds, [237][238][239] metallic stannate, [ 240,241 ] -germanate, [ 242,243 ] -tungstate, [ 244,245 ] -oxides, [ 246,247 ] germanium oxide, [ 248 ] lithium vanadate, [ 249 ] manganese ferrite [ 250 ] and cobalt carbonate [ 251 ] were introduced. They generally showed an increased specifi c gravimetric capacity but, except for a few cases, [ 229,234,237,247 ] the 1 st cycle irreversibility was always higher than 30%.…”

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...

“…Therefore, development of advanced anode materials attracts great attention of the researchers worldwide. Among them, metal sulfides are promising material due to their high capacities (Zhong et al 2012;Vaughn et al 2012;Lai et al 2012;Liu et al 2012a;Gu et al 2013;Fei et al 2013). Molybdenum disulfide (MoS 2 ) is an ''inorganic analogue of graphene'', which has drawn particular research interest: it has a very high capacity about 670 mAh g -1 upon insertion of 4 mol of Li ?…”

A hierarchical MoS 2 architecture composed of nanosheet-assembled microspheres with an expanded interplanar spacing of the (002) planes was successfully prepared via a simple hydrothermal reaction. Electron microscopy studies revealed formation of the MoS 2 microspheres with an average diameter of 230 nm. It was shown that the hierarchical structure of MoS 2 microspheres possesses both the merits of nanometer-sized building blocks and micrometer-sized assemblies, which offer high surface area for fast kinetics and buffers the volume expansion during lithium insertion/deinsertion, respectively. The micrometer-sized assemblies were found to contribute to the enhanced electrochemical stabilities of the electrode materials. The mentioned advantages of the MoS 2 electrode prepared in this work allowed enhanced cyclability and high rate capability of the material. Along with this, the material delivered a high initial discharge capacity of 1206 mAh g -1 and a reversible discharge capacity of 653 mAh g -1 after 100 cycles at a current density of 100 mA g -1 . Furthermore, the material delivered a high reversible capacity of 480 mAh g -1 at a high current density of 1000 mA g -1 .
