“…The bending of the charging plot might be due to the high reactivity of the graphene with the electrolyte at slow charging rate and this effect has been seen previously with graphene [40] by other authors as well. The discharge capacities as high as 161 mAh/g were obtained at C/10 rate, which are higher than the capacities reported for the LiFePO 4 /rGO electrodes [40][41][42]. The performance of the LiFePO 4 depends on the Li ?…”

One of the challenges in incorporating reduced graphene oxide (rGO) in energy storage material is to synthesize the homogenized mixtures of rGO with the electrode active materials at molecular level. In this direction, we have synthesized flexible, thin sheets of rGOwrapped LiFePO 4 plates using aqueous GO solution and precursors of LiFePO 4 . The in situ rGO provides necessary conductivity required for the charge storage performance. The LiFePO 4 /rGO composite was used as a active material without using any conductive carbon additive. The composite could be able to deliver the energy as high as about 161 mAh/g at C/10 rate and posses good cyclability. The high energy storage capabilities of LiFePO 4 is due to the wrapping of highly conductive thin rGO sheets, which increases the electronic conductivity of the LiFePO 4 .

“…Wang et al, have synthesized LiFePO 4 /rGO composites by hydrothermal method [41]. The full cell characteristics have been studied using LiFePO 4 as a cathode and composite TiO 2 /rGO as an anode [42]. Ding et al, have synthesized LiFePO 4 /rGO by co-precipitation method using the rGO dispersion [43].…”

“…In 2010, a full-cell having a graphene-containing material as the anode was reported for the fi rst time by T. Duong et al [ 375 ] ( Table 3 ). By using a graphene/TiO 2 composite [ 111 ] coupled with a LiFePO 4 cathode, the full-cell exhibited negligible performance degradation after 700 cycles at 1 C rate (i.e., 170 mA g −1 ) in the potential range 2.5-1 V, reaching a maximum power density of 4.5 kW kg −1 (limited by the cathode) and energy density of 263 Wh kg −1 (limited by the anode).…”

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...

“…Generally, there are two methods to prepare TiO 2 -graphene hybrids: direct compounding [9][10][11][12][13][14][25][26][27][28][29] and in situ method [15][16][17][18][19][20][21][22][23][24][30][31][32][33][34][35][36][37][38][39][40][41][42][43]. Unfortunately for the former method, TiO 2 could be only decorated on certain partial of graphene because of the lack of functional groups on graphene and the interaction between them was rather weak.…”
