“…When using PVDF as a binder, it was found that the capacities for all the samples were high for the first few cycles; however, the discharge capacities decreased dramatically over 10 cycles and only showed 250, 157, and 102 mAh g -1 (for the 0.1, 0.3 and 0.5 mol L -1 precursor concentrations, respectively) after 40 cycles. This phenomenon has been reported in previous publications [15]. In order to improve the cycling stability of the NiO samples prepared by the spray pyrolysis method, CMC binder was tested using the asprepared NiO powders.…”

Hollow spherical NiO particles were prepared using the spray pyrolysis method with different concentrations of precursor. The electrochemical properties of the NiO electrodes, which contained a new type of binder, carboxymethyl cellulose (CMC), were examined for comparison with NiO electrodes with polyvinylidene fluoride (PVDF) binder. The electrochemical performance of NiO electrodes using CMC binder was significantly improved. For the cell made from 0.3 mol L -1 precursor, the irreversible capacity loss between the first discharge and charge is about 43 and 24% for the electrode with PVDF and CMC binder, respectively. The cell with NiO-CMC electrode has a much higher discharge capacity of 547 mAh g -1 compared to that of the cell with NiO-PVDF electrode, which is 157 mAh g -1 beyond 40 cycles.

“…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. Lastly, the NiO nanocuboids can achieve very high rate capability of 12C (12Ag-1) AbstractNanocuboid shaped 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.

“…For example, forming composites with conductive materials such as carbon is a very common and useful method, but often reduces the mass specific capacity [11,12]. So, preparing materials with a special morphologies such as a porous structure [13][14][15][16], nanoarrays [6,17], microspheres [18][19][20][21][22] and some others [23] to enhance the electrochemical performance has attracted much attraction.…”
