“…Regarding previously developed graphene-containing composites, many different semimetal-(e.g., Si [206][207][208][209] ), metal-(e.g., Sn [210][211][212][213] ) and metal-oxide-(e.g., NiO, [214][215][216] [ 225,226 ] or CoO [ 227,228 ] ) based graphene hybrids were further reported. 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.…”

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...

“…In this regard, metals, their sulfides, oxides, phosphides and alloys bring very interesting performances 25, 116, 117, 118, 119, 120, 121. But these performances are also accompanied by new fundamental issues related to their structural change, volume expansion, uncontrolled SEI film formation, and low conductivity that results in poor cyclic life 21, 37, 97, 122, 123, 124. Among metal sulfides, Co 3 S 4 has been considered a promising anode material for Li‐ion battery due to its high theoretical capacity (702.8 mAh g –1 ).…”

Lithium‐based batteries possessing energy densities much higher than those of the conventional batteries belong to the most promising class of future energy devices. However, there are some fundamental issues related to their electrodes which are big roadblocks in their applications to electric vehicles (EVs). Nanochemistry has advantageous roles to overcome these problems by defining new nanostructures of electrode materials. This review article will highlight the challenges associated with these chemistries both to bring high performance and longevity upon considering the working principles of the various types of lithium‐based (Li‐ion, Li‐air and Li‐S) batteries. Further, the review discusses the advantages and challenges of nanomaterials in nanostructured electrodes of lithium‐based batteries, concerns with lithium metal anode and the recent advancement in electrode nanostructures.

“…In accord with previous results, the first cycle shows lots of differences from the subsequent ones on CV curves, especially on the discharge branch. 29,50,84 In the first discharge process, the obvious cathodic peak was located at around 0.97 V, which was attributed to the electrochemical reduction of Co 3 O 4 to metallic cobalt accompanying the formation of Li 2 O and the solid electrolyte interphase (SEI) film. [84][85][86] In the anodic process, broad peaks located at around 2.15 V can be ascribed to the reversible oxidation reaction from cobalt to Co 3 O 4 .…”

[29][30][31] Up to now, many nanoparticles (NPs) M x O y /graphene composites have been investigated as LIB anode materials, such as SnO 2 /graphene, [32][33][34] Mn 3 O 4 /graphene, 35 CuO/graphene, 36 and Fe 2 O 3 /graphene. 37 They usually exhibit much better electrochemical performance than their bare counterparts.…”

How to improve the stability and rate performance of lithium-ion batteries with transition metal oxide anodes

et al. 2016

The lithium ion battery is the most promising battery candidate to power battery electric vehicles. For these vehicles to be competitive with those powered by conventional internal combustion engines, significant improvements in battery performance are needed, especially in the energy density and power delivery capabilities. Promising substitutes for graphite as the anode material include silicon, tin, germanium, and various metal oxides that have much higher theoretical storage capacities and operated at slightly higher and safer potentials. In this critical review, metal oxides-based materials for lithium ion battery anodes are reviewed in detail together with the progress which is made in my lab on that topic. Their advantages, disadvantages, and performance in lithium ion batteries are discussed through extensive analysis of the literature, and new trends in materials development are also reviewed. Two important future research directions are proposed and performed in my lab, based on results published in the literature: the development of composite and nanostructured metal oxides to overcome the major challenge posed by the high capacity of metal oxide anodes.
