“…Different forms have been investigated. Recently, the dependence of the performance of CuO anodes on the morphology has been studied [531]. As a result, the reversible capacity of the leaf-like CuO decreases during cycling, which confirms prior results found by different groups on CuO particles with this morphology [532,533], and such is also the case for oatmeal-like CuO.…”

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...

“…CuO has also been reported as one of the anode materials for LIBs. [31][32][33][34][35][36] The composite of CuO/graphene applied as an anode material for LIB and as a supercapacitor material has been studied. 14,15,[37][38][39] However, N-GO or N-GO/CuO as an anode material for LIBs has not been studied widely.…”

A nitrogen-doped graphene oxide/copper oxide (N-GO/CuO) nanocomposite is prepared through a modified Hummers method followed by heat treatment. The composite is characterized by scanning electron microscopy and transmission electron microscopy, and the results show crumpled and curved graphene oxide nanosheets with uniformly distributed CuO nanoparticles. The composition of N-GO/ CuO is further studied by Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). The electrochemical behaviors of N-GO/CuO as an anode material for lithium ion rechargeable batteries are investigated by galvanostatic discharge-charge measurements and cyclic voltammetry. N-GO/CuO exhibits a high reversible capacity of 472 mA h g À1 under the current density of 372 mA g À1 with excellent capacity retention of 99.7% over 100 cycles and improved rate capacities. This work demonstrates that N-GO/CuO is a promising anode material for lithium ion batteries.

“…In the first cathodic sweep, a broad and weak reduction peak presents at 1.55~1.95 V, which is corresponding to the formation of Li x CuO. 30 Then two sharp peaks are observed at around 1.0 and 0.65 V in succession, which can be attributed to the phase transformation from Li x CuO to Cu 2 O and further to Cu(0), respectively. Additionally, a solid electrolyte interphase (SEI) layer generates on the electrode surface at lower voltage (below 0.5 V).…”

“…Their remarkably high capacity is based on the redox mechanism (MO X +2xLi+2xe -↔M+xLi 2 O) by delivering multiple electrons. 1- 30 3 Among these materials, copper oxide (CuO) is a potential substitute for conventional graphite anode for its high theoretical capacity (674 mAh g -1 ), environmental friendly nature, high safety and low cost. [4][5][6][7][8] However, its huge and uneven volume expansion during Li + insertion/extraction processes (about 174%) 35 leads to the pulverization and deterioration of CuO structures, resulting in rapid capacity decay and poor rate capabilities.…”

5Three-dimensional hierarchical CuO nanostructures with uniform flower-like and urchin-like morphologies have been successfully prepared by a facile, cheap and environmental friendly solvothermal method. The as-prepared flower-like CuO is constructed by nanopetals, which is composed of 10 nanoparticles, and the urchin-like CuO with hollow structure is composed of tightly ranged nanorods. As anode materials for lithium-ion batteries, the flower-like CuO material exhibits high initial discharge capacitance (1457.2 mAh g -1 at 100 mA g -1 ), good rate capability and excellent cycling 15 stability. The superior electrochemical performance is mainly attributed to the hierarchical structure and the nanosize of the nanoparticles composed of the nanopetals, which benefit electrons and Li ions transportation, provide large electrodeelectrolyte contact area. The extra capacity of the samples 20 may due to the partial reversible formation and decomposition of the gel-like SEI film on the surface of the electrode and pseudocapacitance. Graphical AbstractThree-dimensional hierarchical CuO nanostructures with uniform flower-like and urchin-like morphologies have been prepared by a facile solvothermal method. The CuO materials display high initial discharge capacitance, good rate capability and excellent cycling stability as anode materials for rechargeable lithium-ion batteries.
