AbstractWearable and portable mobile phones play a critical role in the market, and one of the key technologies is the flexible electrode with high specific capacity and excellent mechanical flexibility. Herein, a wire-in-wire TiO2/C nanofibers (TiO2 ww/CN) film is synthesized via electrospinning with selenium as a structural inducer. The interconnected carbon network and unique wire-in-wire nanostructure cannot only improve electronic conductivity and induce effective charge transports, but also bring a superior mechanic flexibility. Ultimately, TiO2 ww/CN film shows outstanding electrochemical performance as free-standing electrodes in Li/K ion batteries. It shows a discharge capacity as high as 303 mAh g−1 at 5 A g−1 after 6000 cycles in Li half-cells, and the unique structure is well-reserved after long-term cycling. Moreover, even TiO2 has a large diffusion barrier of K+, TiO2 ww/CN film demonstrates excellent performance (259 mAh g−1 at 0.05 A g−1 after 1000 cycles) in K half-cells owing to extraordinary pseudocapacitive contribution. The Li/K full cells consisted of TiO2 ww/CN film anode and LiFePO4/Perylene-3,4,9,10-tetracarboxylic dianhydride cathode possess outstanding cycling stability and demonstrate practical application from lighting at least 19 LEDs. It is, therefore, expected that this material will find broad applications in portable and wearable Li/K-ion batteries.

In this article, Ag2O/carbon nanotubes (CNTs) nanocomposite has been prepared by chemical reduction method and used as a cathode material for zinc-silver batteries. The transmission electron microscopy (TEM) tests reveal the CNTs and Ag2O nanotubes form an interpenetrating network structure. The X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) analysis confirmed that the Ag2O shows Cubic (Pn-3) crystal structure and mixture element states in the nanocomposite. The charging/discharging property of the Ag2O/CNTs nanocomposite was studied by galvanostatic charge-discharge measurement as a cathode material. The results indicated that Ag2O/CNTs nanocomposite has high specific capacity and good cycling stability. For the current density of 0.53 mA/cm2 (2.5C), the initial specific capacity of the nanocomposite is 190 mAh/g and remains 172 mAh/g after 20 cycles.
