We present a facile, up-scalable and cost-effective strategy to prepare defect-laden holey graphene counterparts for energy-related applications.
3D spherical and crumpled-ball graphene-based architectures with diverse, fascinating properties and applications are reviewed for the first time.
In this study, we synthesize two layered and amorphous structures of germanium phosphide (GeP<sub>5</sub>) and compare their electrochemical performances to better understand the role of layered, crystalline structures and their ability to control large volume expansions. We compare the results obtained with those of previous, conventional viewpoints addressing the effectiveness of amorphous phases in traditional anodes (Si, Ge, and Sn) to hinder electrode pulverization. By means of both compreh
The structural evolution of Cu–12 wt·%Ge (∼Cu–11 at·%Ge) alloy processed by means of mechanical alloying (MA) with subsequent heat treatment was studied using X-ray diffraction profiles, scanning electron microscopy, transmission electron microscopy (TEM) and high resolution TEM observations as well as differential thermal analysis(DTA). The fcc Cu(Ge) solid solution (α) was produced at early stages of MA and amorphised upon further milling. This was followed by the formation of ζ−Cu5Ge intermet
Ion and electron transportation determine the electrochemical performance of anodes in metal-ion batteries. This study demonstrates the advantage of charge transfer over mass transport in ensuring ultrastable electrochemical performance. Additionally, charge transfer governs the quality, composition, and morphology of a solid-electrolyte interphase (SEI) film. We develop FeSi<sub>4</sub>P<sub>4</sub>-carbon nanotube (FSPC) and reduced-FeSi<sub>4</sub>P<sub>4</sub>-carbon nanotube (R-FSPC) hetero
