“…[ 326 ] Nevertheless, some new hybrids were introduced in the LIB anode fi eld too. Indeed, graphene-containing glassy metal alloy nanofi ber, [ 327 ] selenides, [328][329][330][331][332] silicates, [ 333,334 ] molybdates, [335][336][337] oxides, [338][339][340][341] intermetallic compounds, [ 342,343 ] intermetallic oxides, [ 344,345 ] oxalate, [ 346 ] sulfi de, [ 347 ] nitride, [ 348 ] carbide [ 349 ] and phosphide [ 350 ] hybrids were reported (see Table 2 ). Despite the usual sloping delithiation voltage and the generally low content of graphene (i.e., ≤30 wt%), few of these hybrids [ 329,331,335 ] showed a low 1 st cycle irreversible capacity (i.e., <20%).…”

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...

“…While, Sn 4 P 3 /CNTs electrode displays an ameliorated cyclicity, it has a promotional increment from ∼30th to 300th cycle, exhibiting a higher reversible discharge capacity of 976.5 mAh g −1 after long 300 cycles. The improvement is encouraged by other researches of transition metal phosphides, which illustrates the reason that the gradual activation and sustainable structure stability of carbon nanotubes‐intertwined nanohybrid with buffering the huge volume expansion and enhancing electrical conductivity ,. This capacity retention could satisfy the demands for new energy internet.…”

Through a one‐step solvothermal approach, the carbon nanotubes‐decorated Sn4P3 nanohybrid with intertwined scaffold structure and enhanced electroconductivity is successfully composed as anode material in lithium‐ion batteries, using nontoxic red phosphorus and SnCl2 as starting materials. The special architecture of the nanohybrid exhibits more active sites for lithium ions and buffers the huge volume expansion. When used as anodes in lithium‐ion batteries, the material shows superior electrochemical properties, 976.5 mAh g−1 after 300 cycles under a constant current density of 500 mA g−1 and 480.0 mAh g−1 even at a high rate current of 2000 mA g−1. This excellent electrochemical behavior can be attributed to the 3D network of CNTs and its critical synergic effect with Sn4P3.

“…4a shows the cyclic voltammetry (CV) curves of the LIB cell with the 1D CoP anode tested at a scan rate of 0.2 mV s À1 between 0.005 and 3.0 V for 3 cycles. During the rst discharge, a broad peak centered at around 1.0 V is observed, which corresponds to the conversion reaction of CoP: CoP + 3Li + + 3e À / Co + Li 3 P. 27,28 The small peak appearing at around 0.6 V can be ascribed to the reaction of CoP + Li + + e À / Co + LiP. 27 The broad peak within the voltage range of 0.55 V to 0.005 V can be attributed to some irreversible reactions, including the formation of a solid electrolyte interphase (SEI) layer.…”

One-dimensional (1D) carbon-supported nanostructured CoP and FeP 4 were prepared using fibrous elastin proteins that served as starting materials through an oil-phase method and the as-synthesized products were investigated for their lithium and sodium storage properties. The 1D CoP and FeP 4 are composed of nanosized particles decorated on carbon supports. The 1D CoP and FeP 4 nanostructures are $2 mm in length and 20-50 nm in diameter. The particles on the exterior of the 1D structure are 5-10 nm in diameter. To investigate the as-synthesized 1D TMPs in energy storage applications, the as-synthesized 1D CoP nanostructures are applied as an anode material in half-cells for LIBs and SIBs. For lithium storage performances, the anode delivers a specific capacity as high as $740 mAh g À1 at 0.2C and shows good rate performance and capacity retention as well as high rate capability (e.g. a stable specific capacity of $365 mAh g À1 for 120 cycles at 3.0C). In SIBs, at 0.2 and 5.0C, the specific capacities of 491.60 and 314.84 mAh g À1 are delivered, respectively. When tested at 1.0, 2.0, and 5.0C, the specific capacities are stable at $400, 360, and 300 mAh g À1 over 250, 250, and 1000 cycles, respectively.
