“…These results also represent the highest reversible capacity reported for NiO nanostructures to-date. More encouraging still, was the high rate capability of the nanocones (rates of 20 C delivered capacities as high as 436 mA h g -1 ), while offering capacities up to initial values on returning to relatively low current rates (C/10) [205]. In contrast, hydrothermally prepared MoO3 nanobelts, with carbon layers in the order of 15 nm, delivered equivalent performance, maintaining capacities greater than 1000 mA h g -1 after 50 cycles [206].…”

Rights © Tsinghua University Press and Springer-Verlag Berlin ABSTRACTThe performance of the lithium-ion cell is heavily dependent on the ability of the host electrodes to accommodate and release Li + ions from the local structure. While the choice of electrode materials may define parameters such as cell potential and capacity, the process of intercalation may be physically limited by the rate of solid-state Li + diffusion. Increased diffusion rates in lithium-ion electrodes may be achieved through a reduction in the diffusion path, accomplished by a scaling of the respective electrode dimensions.In addition, some electrodes may undergo large volume changes associated with charging and discharging, the strain of which, may be better accommodated through nanostructuring. Failure of the host to accommodate such volume changes may lead to pulverisation of the local structure and a rapid loss of capacity. In this review article, we seek to highlight a number of significant gains in the development of nanostructured lithium-ion battery architectures (both anode and cathode), as drivers of potential next-generation electrochemical energy storage devices.

“…Recent examples of note include reports of NiO nanocones [205], and MoO3/C nanobelts [206], which display high capacity and excellent cycling ability. NiO nanocones, which were prepared by the electrodeposition of acidic NiCl2.6H2O solutions directly on Ni foams, offered capacities in excess of 1000 mA h g -1 , even after 100 cycles.…”

“…Nevertheless, NiO anodes often suffer from serious capacity fade during the discharge/charge process due to volume expansion/extraction and poor ionic conductivity [5]. Recent studies on various NiO structures including porous nanocomposite [9], nanowalls [10], hollow microspheres [11,12], hollow nanotubes [13,14], nanosheet-based microspheres [15], nanocone array [16], nanofilms [17], nanowires [18], and mesoporous NiO crystals [19] show great promise in overcoming these issues. Several research groups investigated the electrochemical performances of NiO electrode which was synthesized by thermal oxidation at low temperature (400-700°C) [20][21][22].…”

Nanogravel structured NiO/Ni electrodes were fabricated by using two-step thermal oxidation method of commercial nickel (Ni) foam in air for lithium-ion batteries (LIBs). The macro-and micro-structures of the NiO/Ni foam were characterized using X-ray diffraction (XRD), scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDX), and Raman spectroscopy. Galvanostatic tests revealed that the electrode exhibits no obvious capacity fading over 40 cycles at 1 C (718 mAg −1 ) and 2.5 C (1.8 Ag −1 ) current rate. The discharge capacity was higher than the theoretical capacity of NiO even at a highcurrent rate of 2.5 C. The electrodes can deliver a reversible capacity of 1116.65 mAh g −1 after 20th cycle at 1 C rate and 1026.20 mAh g −1 after 40th cycle at 2.5 C rate. The cyclic voltammograms and impedance spectra analysis indicated that a redox reaction of NiO-Ni 0 with formation and decomposition of Li 2 O. The excellent electrochemical performance is mainly attributed to the nanogravel structure of the NiO/Ni foam electrodes as well as its excellent electrical contact between NiO and Ni. The unique nanostructured NiO on the highly conductive metallic Ni in core resulted in the enhanced discharge capacity, coulombic efficiency, cyclic stability, and rate capability when utilized as negative electrodes in LIBs.

“…In addition, nanostructured morphologies of transition metal oxides could affect the electrochemical lithium storage properties. Nickel oxides with different morphologies such as nanoparticles, [9] nanofibers, [10] nanotubes, [11] nanowalls, [12] nanoshafts, [13,14] nanocones, [15] nanoflakes, [16][17][18] nanostructure hierarchical spheres, [19] and mesoporous structures [20] have been previously studied. In addition, nickel oxide composites with different carbon structures such as carbon coatings, [21,22] carbon nanotubes, [10,23] conducting polymers, [24,25] and graphene [26][27][28] In this work, we used an optical floating zone furnace to synthesize cubic-shaped NiO nanocrystals.…”

Energy, 58 (September), 707-713.The effects of FEC (fluoroethylene carbonate) electrolyte additive on the lithium storage properties of NiO (nickel oxide) nanocuboids AbstractNanocuboid shaped NiO (nickel oxide) has been synthesized using an optical floating zone furnace. It was found that the nanocuboids exhibit single crystalline nature, and have clean and sharp edges. Furthermore, the NiO nanocuboids were tested for their electrochemical performances as anode material for LIBs (lithium-ion batteries) in a coin-type half cell. The effects of FEC (fluoroethylene carbonate) additive on the lithium storage performance were also investigated, which is the first of such studies for transition metal oxides. It was found that FEC has a positive effect on the cycling stability and also improves the rate performances of the nanocuboids. The capacity recorded at 0.1C (100mAg-1) after 50 charge/dischargecycles is 1400mAhg-1.
