A multilayered carbon–-Polytetrafluoroethylene/graphite sheet (C-PTFE/GS) coating is synthesized on a Ti plate by hydrothermal and immersion method. The innermost layer is composed of amorphous carbon and the outermost layer is made of a compound with PTFE, graphite sheets and nanotube. Interfacial contact resistance (ICR) decreases to 8.9 mΩ·cm−2 at the applied force of 1.4 MPa between carbon paper and the substrate with coating. The corrosive current density is only 0.49 μA/cm2 at the cathode, while the potential of 0.6 V is applied. The charge transfer resistance of the multilayer carbon coating is higher than that of a bare sample through the results of electrochemical impedance spectroscopy. Moreover, there are no obvious changes in the coating before and after potentiostatic polarization testing by X-ray photoelectron spectroscopy (XPS) analysis, which demonstrates the stability of multilayered C-PTFE/GS coating on Ti. In addition, the surface morphology of C-PTFE/GS coating is preserved without defect after potentiostatic polarization in a simulated environment of proton exchange membrane fuel cells (PEMFCs). Therefore, the C-PTFE/GS coating is potentially applied as bipolar plates in PEMFCs. Full article

NiCo2O4@NiCo2O4 core-shell nanostructures anchored on Ni foam (NF) are synthesized by the hydrothermal and subsequent calcination process. In these structures, NiCo2O4 nanosheets are coated on NiCo2O4 nanocones, which are decorated on the surface of conductive NF. As an oxygen evolution reaction catalyst, the NiCo2O4@NiCo2O4 exhibits low overpotential of 440 mV at the current density of 100 mA cm−2. Furthermore, the composite shows outstanding long-term stability during 12 h continuous operation. Electrochemical impedance spectroscopy (EIS) reveals that the charge transfer resistance of NiCo2O4@NiCo2O4 is much smaller than other composites. The results reveal that the composite exhibits superior activity for OER in contrast to individual NiCo2O4 nanosheets or NiCo2O4 nanocones, which are attributed to the NiCo2O4@NiCo2O4 composite and integrate multiple advantages of nanostructures, abundant catalytic sites and outstanding stability.

Sodium/potassium-ion batteries have drawn intensive investigation interest from researchers owing to their abundant element resources and significant cost advantages. Anode materials based on alloy reaction mechanisms have the prominent merits of a suitable reaction potential and high theoretical specific capacity and energy density. However, very large volumetric stresses and volume changes during the charge/discharge process and the resulting electrode structural cracking, deactivation and capacity fading seriously hinder their development. To date, a series of modification strategies have been proposed to tackle these challenges and achieve good electrochemical performance. Herein, we review the recent advances in the structural engineering of alloy-type anodes for sodium/potassium storage, mainly including phosphorus, tin, antimony, bismuth and related alloy materials, from the perspective of dimensional structure. Furthermore, some future research directions and unresolved issues are presented for the investigation of alloy-based anode materials. It is hoped that this review can serve as a guide for the future development and practical application of sodium/potassium-ion batteries. Full article
