Abstract
In an effort to minimize irreversible capacity loss and volume expansion, research on Si nanocomposite materials with a SiO_x/Mg₂SiO₄/SiO_x structure through a magnesiothermic reduction process (MTR) has attracted much attention from researchers. Mg₂SiO₄(forsterite) has been shown to improve the initial coulombic efficiency (ICE) by minimizing the irreversible capacity loss due..... More

Abstract
Due to its high theoretical capacity in the conversion reaction, Co₃O₄, a transition metal oxide, has been attracting attention as an anode material for lithium-ion batteries. Comparing conventional slurry method with the electrophoretic deposition (EPD) method without additives (conductive agents and binders), we investigated the effect of the Co₃O₄/additive interface.....

Abstract
In this work, MnO₂ nanoparticles were embedded in a carbon matrix as a porous composite, fabricated using a simple chemical route followed by low-temperature annealing, with activated carbon (AC) as the carbon source in the composite preparation. The porous MnO₂/carbon structures contained some selective nanoparticles coated with carbon. The structural..... More

Abstract
Lack of understanding on the electrical properties of the solid electrolyte interface (SEI) has been one of the major hurdles for developing fast charging Li-ion batteries. Here, we report our preliminary experimental result on the measurement of the electrical resistivity of SEI using the direct-contact technique based on electron microscopy..... More
