“…Recently, much time and effort has been employed in developing materials for asymmetric supercapacitors which take into account factors such as fabrication costs, environmental concerns, and scalability. These materials include -C // RuO 2 [19], Ni-C // Ni(OH) 2 [20], AC // PEDOT [21] Manganese dioxide / graphene sheet composites ranged from 84%-97% between 1000 cycles and 5000 cycles respectively [5,27,28]. In addition, the interfacial capacitance of 0.11 F/cm 2 is comparable to the required value of interfacial capacitance > 0.10 F/cm 2 for commercial devices used in peak power demands of pulsed loads in battery-powered electronics [29][30][31].…”

(2013). Manganosite-microwave exfoliated graphene oxide composites for asymmetric supercapacitor device applications. Electrochimica Acta, 101 99-108.Manganosite-microwave exfoliated graphene oxide composites for asymmetric supercapacitor device applications AbstractGraphene based materials coupled with transition metal oxides are promising electrode materials in asymmetric supercapacitors owing to their unique properties which include high surface area, good chemical stability, electrical conductivity, abundance, and lower cost profile over time. In this paper a composite material consisting of graphene oxide exfoliated with microwave radiation (mw rGO), and manganosite (MnO) is synthesised in order to explore their potential as an electrode material. The composite material was characterised by scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were used to explore the process occurring at the electrode/electrolyte interface. Long term cyclability and stability were investigated using galvanostatic charge/discharge testing. From the resulting analysis, an asymmetric supercapacitor was constructed with the best composite containing 90% MnO-10% mw rGO (w/w). The device exhibited a capacitance of 0.11 F/cm2 (51.5 F/g by mass) and excellent capacity retention of 82% after 15,000 cycles at a current density of 0.5 A/g.

“…A hybrid material consisting of MnO nanocrystals grown on conductive graphene nanosheets exhibits a reversible capacity as high as 2014.1 mAh g À1 after 150 discharge/charge cycles at 200 mA g À1 , excellent rate capability (625.8 mAh g À1 at 3000 mA g À1 ), and superior cyclability (843.3 mAh g À1 even after 400 discharge/charge cycles at 2000 mA g À1 with only 0.01 % capacity loss per cycle) [559]. This is to our knowledge, the best performance in terms of rate capacity and cyclability obtained with MnO, which illustrates the constant progress in the synthesis of MnO-graphene composites since 2011 [560][561][562][563][564].…”

Lithium-ion batteries (LiBs) have made considerable progress since the first commercial one by Sony in 1991, which had LiCoO 2 and graphite as active elements of the positive and negative electrodes, respectively. The LiBs are now the primary energy storage devices in the transportation and communications, from portable use in computers, up to electric and hybrid vehicles. More recently, they have also been used as back-up supply units, frequency regulators (load leveling) to integrate on smart grids the electricity produced by windmills and photovoltaic plants (for a recent review, see [1]). These applications require high energy densities, high power, and safety among others. Considerable efforts have been made to propose other electrodes to fulfill these requirements. We have recently reviewed the works and progress concerning the materials for the positive electrode [2][3][4][5][6]. The present work is devoted to the materials for the negative electrode counterpart. It is common to use the terminology anode and cathode for the negative and positive electrodes, respectively, although the electrodes play alternatively the role of anode and cathode during the charge and discharge process. We shall use this terminology in the following for conciseness purposes only.An ideal active anode element should fulfill the following requirements as follows: (1) It must be light and accommodate as much Li as possible to optimize the gravimetric capacity. (2) Its redox potential with respect to Li 0 /Li + must be as small as possible at any Li-concentration. The reason is that this potential is subtracted to the redox potential of the cathode material to give the overall voltage of the cell, and smaller voltage means smaller energy density. (3) It must possess good electronic and ionic conductivities since faster motion of the lithium ions and the electrons also mean higher power density of the cell. (4) It must not be soluble in the solvents of the electrolyte and not react with the lithium salt. (5) It must be safe, i.e. avoid any thermal runaway of the battery, a criterion that is not independent of the previous one, but deserves special attention, especially for use in transportation such as electric vehicles and planes. (6) It must be cheap and environmentally friendly. The different materials proposed as anode elements for Li-ion batteries must be discussed with respect to these different criteria.The graphite is still the most used anode material and is still the reference. The first works giving evidence of the insertion of lithium in graphite date from 1955 [7], confirmed by the synthesis of LiC 6 in 1965 [8]. The synthesis of LiC 6 , however, was not obtained by electrochemical process at that time. Another decade was spent before Besenhard and Eichinger discovered the reversible intercalation of lithium in graphite, proposing this material as an anode in 1976 [9,10]. Increasing the Li content in LiC 6 is possible [8], but no reversible cycling beyond LiC 6 could ever be obtained. The graphite anode can thus be cyc...

“…The stable and reliable lithium cycling properties of MnO/GNS were also confi rmed in several separate reports. [ 303,304 ] In early work, a reversible capacity of 635 mAh g −1 at 0.2 C in the voltage range between 0.01-3.5 V and a superior rate capability of 410 mAh g −1 at 5 C for MnO nanocrystal/GNS composites were explored by Hsieh et al [ 303 ] The fact that early studies have already achieved such a high percentage of theoretical capacity is impressive.…”

Graphene‐containing nanomaterials have emerged as important candidates for electrode materials in lithium‐ion batteries (LIBs) due to their unique physical properties. In this review, a brief introduction to recent developments in graphene‐containing nanocomposite electrodes and their derivatives is provided. Subsequently, synthetic routes to nanoparticle/graphene composites and their electrochemical performance in LIBs are highlighted, and the current state‐of‐the‐art and most recent advances in the area of graphene‐containing nanocomposite electrode materials are summarized. The limitations of graphene‐containing materials for energy storage applications are also discussed, with an emphasis on anode and cathode materials. Potential research directions for the future development of graphene‐containing nanocomposites are also presented, with an emphasis placed on practicality and scale‐up considerations for taking such materials from benchtop curiosities to commercial products.
