“…Following the trend begun in 2014, this year was mainly characterized by a large number of works focused on long-term cyclability tests (e.g., ≥1000 cycles), generally performed at medium/high currents (e.g., ≥1 A g −1 ). Indeed, graphene-containing insertion (e.g., Li 3 VO 4 , [351][352][353] TiO 2 [ 354,355 ] and LTO [ 356 ] ), conversion (e.g., CoFe 2 O 4 , [ 357 ] Co 3 O 4 , [ 358 ] FeS 2 , [ 359 ] ) and alloying (e.g., Si [360][361][362] and SnO 2 [ 363 ] ) binary hybrids, as well as ternary analogues, [364][365][366][367] showed remarkable results in terms of specifi c gravimetric capacity retained after long cycling. Moreover, other intermetallic compounds (e.g., SnSb [ 368,369 ] ) and metal oxides (e.g., Fe 3 O 4 [ 370,371 ] and MnO [ 372 ] ), when combined with graphene, showed improved cycling stability with respect to their bare analogues.…”

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 electrode showed both good rate and cycling performances with charge capacities of 193 and 167 mAh g −1 after 1000 cycles at 5 and 10 A g −1 , respectively. [205] Olivine-type LiMPO 4 (M = Fe, Mn, Co, Ni) nanosheets with exposed (010) surface facets were fabricated by employing a solvothermal lithiation process in SC ethanol-water solution (Figure 10a-f). Likewise, the hydrogen-terminated groups and defects on the carbon sheets were also proposed to contribute to enhancement in Na ion uptake.…”

Supercritical Fluid‐Facilitated Exfoliation and Processing of 2D Materials

et al. 2019

View full text Add to dashboard Cite

Since the first intercalation of layered silicates by using supercritical CO2 as a processing medium, considerable efforts have been dedicated to intercalating and exfoliating layered two‐dimensional (2D) materials in various supercritical fluids (SCFs) to yield single‐ and few‐layer nanosheets. Here, recent work in this area is highlighted. Motivating factors for enhancing exfoliation efficiency and product quality in SCFs, mechanisms for exfoliation and dispersion in SCFs, as well as general metrics applied to assess quality and processability of exfoliated 2D materials are critically discussed. Further, advances in formation and application of 2D material–based composites with assistance from SCFs are presented. These discussions address chemical transformations accompanying SCF processing such as doping, covalent surface modification, and heterostructure formation. Promising features, challenges, and routes to expanding SCF processing techniques are described.

“…Accordingly, SnO 2 as an electrode material shows large initial irreversible capacity and low initial coulombic efficiency (ICE), about 52.4% of the theoretical ICE value if conversion reaction is fully irreversible; that is more than twice of commercial graphite (372 mAh g −1 ) [3]. Second, SnO 2 anode has still not been achieved mainly due to its capacity to rapidly fade during cycling, huge volume changes of up to 300%, and the severe interparticle aggregation of SnO 2 , which usually results in the loss of electrical contact with current collector caused by large volume changes and pulverization occurring during lithium insertion/extraction [4]. Various methods have been developed to overcome the abovementioned problems such as morphology and size control of SnO 2 nanoparticles [5–12] and SnO 2 -based composite materials [4, 13–21].…”

Natural sepiolite (Sep) nanofibers were coated with carbon and nanoscale SnO2 to prepare an emerging nanocomposite (SnO2–C@Sep), which exhibited enhanced electrochemical performance. Sepiolite could act as a steady skeleton, carbon coating principally led sepiolite from an isolated to an electric state, and decoration of nanoscale SnO2 was beneficial to the functionization of sepiolite. Cycling performances indicated that SnO2–C@Sep showed higher discharge capacities than commercial SnO2 after 50 cycles. The nanocomposite SnO2–C@Sep possessed enhanced lithium storage properties with stable capacity retention and low cost, which could open up a new strategy to synthesize a variety of functional hybrid materials based on the cheap and abundant clay and commercialization of lithium-metal oxide batteries.
