“…A peak current density and total charge were significantly lower compared to reduction peaks indicating a reaction predominant irreversibility. This differs from observation for Cu 2 O nanorods [18], CuO nanostructures [19,20,21] or Cu(OH) 2 nanoflowers [22], where significant oxidation peak was present at 2.2–2.7 V vs. Li/Li + . The lithiation reversibility in metal oxides/hydroxides is strongly affected by their morphology.…”

Lithium primary cells are commonly used in applications where high energy density and low self-discharge are the most important factors. This include small coin cells for electronics, power backup batteries for complementary metal-oxide-semiconductor memory or as a long-term emergency power source. In our study we present a fast, electrochemical method of the positive electrode preparation for lithium primary cells. The influence of the current density and oxygen presence in a solution on the preparation of the electrode and thus its electrochemical behavior is examined. Electrode compositions were characterized by X-ray photoelectron spectroscopy (XPS). The prepared electrodes may be used in Li cells as competition to Zn-MnO2 primary batteries.

“…On the other hand, the Cu 2p 3/2 and Cu 2p 1/2 peaks of Cu 2p electrons for the CuO NWs@Cu foam anode shift to the higher binding energies of 934.2 and 954.3 eV, respectively. Strong Cu 2+ satellite peaks located at 941.8, 944.3 and 962.8 eV are observed in the Cu 2p spectrum of the CuO NWs@Cu foam electrode, confirming the presence of CuO on the anode surface 15 . The core-level spectrum for O 1s is displayed in Fig.…”

“…The slight performance fading was due to the formation of stable SEI interface layers. In order to clearly evaluate the performance of CuO NWs@Cu foam electrode, a detailed comparison between the present electrode and the reported CuO electrodes based on different synthesis methods and structures is shown in Table 1 15 , 17 , 25 , 27 – 32 . The superiority of the freestanding hierarchical porous structure of the present electrode, which guaranteed excellent electrochemical properties, can be seen from the table.…”

To remit capacity fading of lithium ion battery (LIB) anodes, freestanding yucca fern shaped CuO nanowires (NWs) on Cu foams are fabricated as anodes by combining facile and scalable anodization of copper foams followed by calcination. The porous and radial configuration of the hierarchical CuO NWs on the Cu foam substrate guarantees the remarkably improved electrochemical performance with durable cycle stability and excellent rate capability compared with CuO NWs on Cu foils. The reversible capacity remains 461.5 mAh/g after 100 repeated cycles at a current density of 100 mA/g, and a capacity of 150.6 mAh/g even at a high rate of 1000 mA/g. By examining the surface morphology of the cycled samples, possible performance fading route is proposed. The 3D CuO NWs network with a porous architecture simutaneously reduces the ion diffusion distances, promotes the electrolyte permeation and electronic conductivity. This novel strategy might open a new window to develop durable CuO based composite anodes for LIBs.

“…Table shows a summary of the recent studies on CuO nanostructure‐based anodes for LIBs. Both the gravimetric and areal capacities of the CuO‐550 electrode were superior to those of previously reported binder‐free CuO electrodes at a current density of 0.1 A g −1 (≈0.15 C) because of the thick nanostructures making up more than a few micrometers of the electrode (Figure ) …”

CuC2O4⋅x H2O was facilely prepared on a Cu–Ni alloy substrate by in situ precipitation‐induced growth by using a mixture of sodium persulfate, hydrogen peroxide, and oxalic acid. Thermal annealing allowed the conversion of CuC2O4⋅x H2O to leaf‐like CuO nanostructures with a thickness of a few tens of micrometers of sub‐sized nanoparticles, which were applied for fabricating binder‐free anodes for lithium‐ion batteries. Ni was a nucleation site for CuC2O4⋅x H2O, which was uniformly formed on the entire substrate. The concentration of each component in the mixture solution caused significant morphological changes because of the different elution of copper ions. CuO nanostructures annealed at 550 °C showed large areal and gravimetric capacity with excellent capacity retention of 95.5 % after 200 cycles at a high current density because of their appropriate structural morphology, which not only allowed the formation of a stable solid electrolyte interphase layer but also enabled a reversible reaction during the charge/discharge process.
