“…Peaks located at 932.5 eV and 952.9 eV were ascribed to the Cu 0 from Cu foil, while the peaks at 933.6 eV and 954.2 eV corresponding to the binding energy of Cu 2p 3/2 and Cu 2p 1/2 , respectively, resulted from the Cu 2+ of CuO . In addition, two satellite peaks at around 941.7 eV and 961.2 eV could be assigned to the fingerprint of the electronic structure of CuO, also confirming the existence of CuO in the final product . Clearly, the XRD and XPS results well demonstrate successful in‐situ growth of CuO on the Cu foil.…”

Developing high-energy-density lithium-ion batteries (LIBs) is of great significance for their wider commercialized application. The design of self-integrated electrodes can be treated as a valid approach to achieve this goal. In this work, a facile and low-cost wet chemical oxidation strategy is put forward to prepare self-integrated porous leaf-like CuO nanoplates on Cu foil substrates in situ. These nanoplates are then directly used as the anode for LIBs. The morphology, structure, and composition of the resultant CuO/Cu hybrid foils are characterized, and the relevant lithium storage properties of this anode are also investigated by using standard electrochemical tests. The results show that the CuO/Cu hybrid-based anode possesses a porous leaf-like morphology and self-integrated architecture. Benefitting from this unique morphology and favorable architecture, the CuO/Cu hybrid-based anode exhibits outstanding electrochemical performance, including excellent cycling stability and remarkable rate capability, demonstrating great potential in the application of high-energy-density LIBs.

“…A semicircle and a slope line can be observed for both of the samples. As reported by Cheng et al [ 36 ], the semicircles relate to the charge transfer resistance which resulted from charge transfer through the electrode/electrolyte interface, while the slope line corresponds to Warburg impedance over Li + diffusion in the solid materials. The impedance data were analyzed by fitting the curves with equivalent electrical circuit shown in the inset of Figure 4 b, where R s and R ct indicate electrolyte resistance and charge transfer resistance, respectively; CPE stands for the corresponding constant phase elements; and R W represents the diffusion-controlled Warburg impedance.…”

By using ZnO nanorods as an ideal sacrificial template, one-dimensional (1-D) ZnS nanotubes with a mean diameter of 10 nm were successfully synthesized by hydrothermal method. The phase composition and microstructure of the ZnS nanotubes were characterized by using XRD (X-ray diffraction), SEM (scanning electron micrograph), and TEM (transmission electronic microscopy) analysis. X-ray photoelectron spectroscopy (XPS) and nitrogen sorption isotherms measurements were also used to study the information on the surface chemical compositions and specific surface area of the sample. The prepared ZnS nanotubes were used as anode materials in lithium-ion batteries. Results show that the ZnS nanotubes deliver an impressive prime discharge capacity as high as 950 mAh/g. The ZnS nanotubes also exhibit an enhanced cyclic performance. Even after 100 charge/discharge cycles, the discharge capacity could still remain at 450 mAh/g. Moreover, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) measurements were also carried out to evaluate the ZnS electrodes.

“…After rinsing with deionized water for several times, the light blue CF was dried under N 2 gas flow and annealed at 180 • C in air at a ramp rate of 2 • C min −1 for 2 h. Then, the final product CuO NWs array was obtained with dark brown color. The principal of CuO NWs array in situ grown on CF could be described as following reactions (Cheng et al, 2016):…”

Self-supported electrodes represent a novel architecture for better performing lithium ion batteries. However, lower areal capacity restricts their commercial application. Here, we explore a facial strategy to increase the areal capacity without sacrificing the lithium storage performance. A hierarchical CuO-Ge hybrid film electrode will not only provide high areal capacity but also outstanding lithium storage performance for lithium ion battery anode. Benefiting from the favorable structural advance as well as the synergic effect of the Ge film and CuO NWs array, the hybrid electrode exhibits a high areal capacity up to 3.81 mA h cm −2 , good cycling stability (a capacity retention of 90.5% after 150 cycles), and superior rate performance (77.4% capacity remains even when the current density increased to 10 times higher).
