The porous carbon nanofiber films (PCNFS) were prepared via electrospinning and sol-gel method using SiO2 as template. Then, a flexible carbon/selenium composite electrode ([email protected]) was obtained by melting and diffusion loading of selenium. The microstructure and morphology of the materials were characterized by X-ray diffraction (XRD), scanning e...
Innovative concepts for novel electrode structures have been actively pursued over recent years to achieve both superior electrochemical performance as well as long-term stability for the development of solid oxide cells (SOCs) with efficient energy conversion. In this study, towards understanding the role of surfaces and interfaces on electrochemi...
Li-CO2 batteries are widely studied as a promising technology for greenhouse-gas CO2 fixation as well as for energy conversion and storage devices. Their further development, however, is hindered by the refractory discharge products, leading to large polarization voltage and low round-trip efficiency. Here, W2C nanoparticles embedded in the walls o...

Lithium-sulfur batteries (LSBs) suffer from sluggish reaction kinetics of sulfur-containing species and loss of soluble polysulfides (PSs) during cycling, especially in the case of liquid electrolytes. Here, we improve the kinetics of sulfur species by decorating Mo2C nanoparticles on carbon nanotubes (CNTs) as the host for sulfur active mass. In a...

Bio-inspired superwetting interfaces can realize rapid transfer of liquid mass or momentum due to their unique surface structure and wetting characteristics. Combined with a suitably electrified material, these special interfaces can further promote the generation or transmission of electrons. Herein, we summarize the latest developments in water-e...
Rechargeable aqueous zinc ion batteries have attracted significant attention for potential applications in large-scale energy storage. However, developing suitable cathode materials with both high capacity and rate performance remains a great challenge. Herein, we report an efficient method for functional materials via controlling the stage of hydr...

The nickel-rich cathode materials (LiNi0.8Co0.15Al0.05O2, NCAs) in Lithium ion batteries often suffer from oxygen loss problems under partially overcharged conditions (> 4.3 V), leading to capacity fading and safety problem. Herein, we utilize a facile ball-milling method to coat the NCAs with a shell of cerium aluminum composite oxide (CeO2-Al2O3)...
