“…It must be, furthermore, stable upon cycling, and possess not only excellent gravimetric (mAh g −1 ) but also volumetric capacity (mAh cm −3 ) at a suffi ciently high mass loading (mg cm −2 ). [ 18,19 ] It should not show large voltage hysteresis between charge and discharge, in order not to sacrifi ce the battery energy effi ciency, [ 19 ] and possess a minimal irreversible capacity during the fi rst cycle. Of course, in order to allow good rate capability, it should provide good mixed conduction (high electrical and ionic conductivity) and, preferentially, be cheap and environmentally friendly.…”

“…[ 20 ] The low intercalation/deintercalation potentials (see Figure 2 , profi le a) and the high Coulombic and voltage effi ciency (i.e., very small hysteresis) are clearly at the basis of its success. Graphite is, indeed, used in all the commercially available rechargeable hard case LIBs [ 17,19 ] although it presents some relevant limitations. It suffers indeed from poor lithium-ion storage capability at low temperatures (e.g., T < 0 °C), Di Wei is a senior research scientist at Nokia Technologies.…”

“…Indeed, as clearly stated by M. N. Obrovac and V. L. Chevrier [ 19 ] "One diffi culty in choosing proper metrics for anodes stems from basic electrochemistry: it is not possible to calculate the energy of a single electrode". Energy and/or power densities of a full-cell employing a specifi c anode material could be, however, estimated from preliminary tests in half-cells.…”

[ 19 ] Such evaluation is rarely found in literature and is also quite diffi cult "a posteriori" due to the lack of specifi c information. [ 19 ] In general, however, gravimetric and volumetric capacity, together with the average lithiation and delithiation voltages are excellent metrics to properly evaluate an anode active material in half-cell confi guration.…”

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...

Graphene Oxide Wrapped Amorphous Copper Vanadium Oxide with Enhanced Capacitive Behavior for High‐Rate and Long‐Life Lithium‐Ion Battery Anodes

et al. 2015

View full text Add to dashboard Cite

Graphene oxide‐wrapped amorphous copper vanadium oxide is fabricated through a template‐engaged redox reaction followed by vacuum dehydration. This material exhibits high reversible capacity, excellent rate capability, and out standing high‐rate cyclability. The outstanding performance is attributed to the fast capacitive charge storage and the in situ formed copper with enhanced electrical conductivity.
