“…Recently, transition metal oxides (M x O y , where M is Cu, Ni, Co, Mn, or Fe) have shown great potential as anode materials for lithium-ion batteries owing to their high safety, high theoretical capacity, low cost and environmental friendliness [4][5][6][7][8][9][10][11]. Unfortunately, there are still many challenging issues in using them for lithium-ion batteries.…”

“…Attempts are made to prepare CuO nanoparticles using different methods such as spray pyrolysis (Chiang et al 2012), electrochemical techniques (Chen et al 2009), hydrothermal treatments (McAuleya et al 2008, sonochemical method (Gandhi et al 2010), and wet chemical methods (Mahapatra et al 2008) with different morphologies. Among these methods, sonochemical preparation method is used to break the chemical bond of the solution compound.…”

In this study, cupric oxide (CuO) nanoparticles were synthesized via sonochemical method. The samples were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscope, and transmission electron microscopy. The spherical CuO nanoparticles were dispersed in sodium hexametaphosphate under sonication (25 kHz) to analyze the particle size distribution and UV absorption spectra. Using these absorption spectra, we further examined the CuO nanoparticle to explore the possibility of using them as a material for applications such as solar cell and textile production.

“…The same holds for hierarchical structures [534]. The morphologies that avoid this capacity fading are the nanowires [535] and the nanoribbon arrays [536]. The nanowires delivered a capacity of 650 mAh g À1 stable over 100 cycles at C/2 rate in the voltage range 0.02-3 V. The nanoribbon arrays showed an initial reversible capacity of 500 mAh g À1 increasing slowly 610 mAh g À1 upon cycling to 275 cycles at C/2 rate in the same voltage range, and the capacity still retained at current density 800 mA g À1 was 332 mAh g À1 .…”

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...
