“…The decrease in the R ct upon doping the NiO with Cu can be put down to the more effective ion and electron transfer. 23 This proves that the Cu-doped NiO electrode demonstrates enhanced electrode reaction kinetics of the lithium ion battery.…”

“…16,17 Appropriate doping of metal ions can be a practical method to improve the electronic conductivity. [18][19][20] In recent years, Thi et al 21 reported a Co-doped NiO nanoparticle, which was prepared via polyol-based solvothermal method, the capacity maintained a value of 1017 mA h g À1 aer 50 cycles at 0.1 C. Chen et al 22 produced Cu-doped CoO hierarchical structures electrode material by hydrothermal reaction, and the capacity maintained was 800 mA h g À1 aer 80 cycles at 0.5 C. Li et al 23 reported the production of Li-doped NiO for anode materials via spray pyrolysis, whereby the electrode revealed outstanding electrochemical property with the capacity of 907 mA h g À1 aer 100 cycles at 0.5 C. This portend that controlled chemical doping of metals has also been proven to strengthen the electrochemical properties of NiO electrode for LIBs. In addition, the ionic radius of Ni 2+ (0.55Å) is similar to Cu 2+ (0.57Å), where there is only small lattice expansion of NiO when the Cu 2+ take the place of Ni 2+ .…”

“…Figure f compares the core level Ni 2p XPS spectra of the NiO and Ni–NiO‐3 samples. The peaks centered at 853.7, 855.6, 860.9, 872.7, and 879.5 eV can be assigned to the characteristic peaks of Ni 2+ , whereas the peaks located at 852.5 and 869.7 eV represent the characteristic Ni 2p 3/2 and Ni 2p 1/2 peaks of Ni 0 , respectively . Apart from the peaks of Ni 2+ , there are noticeable characteristic peaks of Ni 0 for the Ni–NiO‐3 sample, indicating the existence of metal Ni.…”

Currently, the main bottleneck for the widespread application of Ni-Zn batteries is their poor cycling stability as a result of the irreversibility of the Ni-based cathode and dendrite formation of the Zn anode during the charging-discharging processes. Herein, a highly rechargeable, flexible, fiber-shaped Ni-Zn battery with impressive electrochemical performance is rationally demonstrated by employing Ni-NiO heterostructured nanosheets as the cathode. Benefiting from the improved conductivity and enhanced electroactivity of the Ni-NiO heterojunction nanosheet cathode, the as-fabricated fiber-shaped Ni-NiO//Zn battery displays high capacity and admirable rate capability. More importantly, this Ni-NiO//Zn battery shows unprecedented cyclic durability both in aqueous (96.6% capacity retention after 10 000 cycles) and polymer (almost no capacity attenuation after 10 000 cycles at 22.2 A g ) electrolytes. Moreover, a peak energy density of 6.6 µWh cm , together with a remarkable power density of 20.2 mW cm , is achieved by the flexible quasi-solid-state fiber-shaped Ni-NiO//Zn battery, outperforming most reported fiber-shaped energy-storage devices. Such a novel concept of a fiber-shaped Ni-Zn battery with impressive stability will greatly enrich the flexible energy-storage technologies for future portable/wearable electronic applications.

“…If the coloring characteristics and ion storage capacity of the NiO thin film can be enhanced, the application of the ECD or CECD devices must be greatly promoted. According to the literatures, the characteristics of electrochromic films can be effectively enhanced by Li-doping [6][7][8][9][10][11]. The Li + ions can provide fast charge transfer carriers as ion transportation in the ECDs [12].…”

In this study: various amounts of Li2CO3 powders were mixed into NiO powders to fabricate the Li- added NiO (NiO:Li) targets. The electrochromic films of LiNiO were deposited on ITO glasses at room temperature (R.T.) by RF magnetron sputtering. The thicknesses of electrochromic LiNiO films were kept about 200 nm. The ECD device was constructed with structure of Glass/ITO/ LiNiO /Gel-electrolyte/ITO/Glass. The results indicated that the optimal electrochromic characteristics of Li0.16Ni0.58O thin films could be obtained by 10 wt% Li2CO3 added NiO target. The optimized characteristics of ECDs could be achieved with the intercalation charge (Q) of 11.93 mC/cm2, the optical density (ΔOD) of 0.38, the transmittance change (ΔT) of 44.1%, and the coloring efficiency (η) of 31.8 cm2/C at the wavelength of 550 nm by setting voltage of 3.2V. The results demonstrate that the doping of Li+ ions into NiO films can effectively enhance the characteristics of ECD devices. The reason may due to the increased amount of charge stored in the electrochromic devices (ECDs).
