While nanostructural engineering holds promise for improving the stability of high-capacity silicon (Si) anodes in lithium-ion batteries (LIBs), challenges like complex synthesis and high cost nano-Si impede its commercial application. In this study, we present a local reduction technique to synthesize micron-scale monolithic layered Si (10–20 μm) with tap density 0.9–1.0 g cm–3 from cost-effective montmorillonite, natural silicate mineral. The created mesoporous structure within each layer,...
Abstract Hollow Cu nano/microstructures are prepared by reduction of CuSO 4 · 5 H 2 O with glucose using a mild hydrothermal process. The X‐ray powder diffraction and energy‐dispersive analysis indicate that the products pure cubic phase. morphology can be controlled between nanotubes microspheres assembled from hollow nanoparticles adjusting concentration sodium dodecyl sulfate. A series experiments confirm NaOH also play important roles in formation nano/microstructures.
Abstract The rapid accumulation of end‐of‐life lithium‐ion batteries necessitates sustainable recycling pathways, particularly for the industry‐prominent nickel‐rich NCM (LiNi x Mn y Co z O 2 , x+y+z = 1, x>0.8) materials. Direct presents a promising solution but is hindered by susceptibility these materials to impurities, moisture, particle cracking, and thermal degradation, especially in hydrothermal relithiation methods. This study reveals that impurities lead severe surface...
Monodispersed vanadium dioxide (VO2) hollow microspheres aggregated by elliptical nanorods were synthesized via a one-step template-free method. The inside-out Ostwald ripening mechanism is responsible for the formation of microspheres.
Despite significant progress in recycling spent lithium-ion batteries (LIBs), nondestructive, direct methods still face untenable discrepancies multiple cathode chemistries, which primarily originate from a variety of structure stabilities during the process. Through systematic investigation microstructure evolution relithiation treatment, we observed inevitably induced defects and Li/Mn disordering LiNi0.5Mn1.5O4 cathode, contributing to sluggish Li+ transport irreversible capacity loss....
Stone knives were used widely in N eolithic E ast A sia, presumably the harvesting of grain crops, but their function has not been clearly understood due to lack study residues from these tools. To address this issue, starch analysis was employed on surface ancient stone and large amounts starches recovered. The sources starches, however, well understood, because crops involves cutting stems rather than direct contact with starchy seeds. determine whether could deposit types residues, we...
A quaternized poly(phthalazinone ether sulfone ketone) (QAPPESK) membrane doped with was prepared and characterized. Infrared NMR spectra indicated that this may have the same mode of conducting proton as polybenzimidazole (PBI) . The QAPPESK showed high conductivity ( at ), good thermostability measured by thermogravimetric analysis. peak power density single cell composite operated dry reached These results show is promising for high-temperature exchange fuel (PEMFC) applications.
