“…The unique hybrid paper exhibited a large reversible capacity (~840 mAh/g after 40 cycles), excellent cyclic stability, and good rate capacity. In another work, Dai et al fabricated self‐binding noble metal (Pt, Au, and Ag)/graphene composite papers, and the papers showed good conductivity and flexibility. Liu et al reported a flexible and robust MoS 2 ‐graphene hybrid paper that exhibited an excellent lithium storage capacity.…”

SUMMARYSustainable development of renewable energy sources is one of the most important themes that humanity faces in this century. Wide use of renewable energy sources will require a drastically increased ability to store electrical energy. Electrochemical energy storage devices are expected to play a key role. With the increased demand in flexible energy resource for wearable electronic devices, great efforts have been devoted to developing high-quality flexible electrodes for advanced energy storage and conversion systems. Because of its high specific surface area, good chemical stability, high mechanical flexibility, and outstanding electrical properties, graphene, a special allotrope of carbon with two-dimensional mono-layered network of sp 2 hybridized carbon, have been showing great potential in next-generation energy conversion and storage devices. This review presents the latest advances on the flexible graphene-based materials for the most vigorous electrochemical energy storage devices, that is, supercapacitors and lithium-ion batteries.

“…[ 199 ] Unfortunately, none of them were able www.advmat.de www.advancedsciencenews.com to overcome the aforementioned drawbacks of graphene for LIB anodes. Other phosphides-(i.e., Ni 2 P [ 200 ] and TiP 2 O 7 [ 201 ] ), Cr 2 O 3 -, [ 202 ] Ag-, [ 203 ] SiO-, [ 204 ] and LiF- [ 205 ] containing graphene hybrids were developed but only in the case of RGO/LiF, an enhancement in terms of gravimetric capacity at high current rate (i.e., 181 mAh g −1 for a specifi c current of 25 A g −1 ) and stability upon cycling (see Table 2 ) were achieved (even if the drawback of the steep delithiation voltage was not circumvented and an erroneous calculation of half-cell power and energy densities were reported). The authors claimed that "The discrete crystalline LiF nanoparticles on the graphene surface effectively suppress electrolyte side reactions, affect the formation of both inorganic and organic SEI components, and consequently reduce the thickness of the SEI fi lm formed, enabling fast Li ion transport at the interface between electrode and electrolyte".…”

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...

“…The XRD patterns of rGO, MoS 2 /rGO, and PtNLs‐MoS 2 /rGO were shown in Figure .a. The diffraction peak of rGO was observed with the characteristic crystal structure (002) at 2 θ values of 24.6° . In XRD data of MoS 2 /rGO, besides the rGO diffraction peak, the peaks at 14,6 o , 34,5 o and 59,2 o correspond to the (002), (100) and (110) crystalline structure of MoS 2 , respectively (JCPDS: 37‐1492).…”

A flexible Platinum Nanoleaves (PtNLs) deposited molybdenum disulfide/reduced graphene oxide composite paper was successfully prepared for catalyzing the hydrogen evolution reaction (HER). Synthesis of composite paper was achieved through vacuum filtration of homogeneous dispersions, consisting of molybdenum disulfide (MoS2) and graphene oxide (GO). After chemical reduction of MoS2/GO paper with HI, it transformed to MoS2/reduced graphene oxide (rGO) paper and used as the working electrode in a three‐electrode cell to deposit PtNLs by electroreduction method. The as‐prepared PtNLs‐MoS2/rGO paper was characterized by X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and Raman spectroscopy. When PtNLs‐MoS2/rGO paper rolled up, it can be used directly as a catalyst with the enhanced surface area in a small space and exhibit high‐performance HER activity with a small onset overpotential of 62 mV and a low Tafel slope of 60 mV/dec as well as excellent electrocatalytic stability. The present work provides a potential way to design catalyst for HER through controlling the shape.
