Li-S battery is becoming a one of the promising alternative to Li-ion battery. It has high theoretical energy density, low cost, eco-friendliness and safety. But polysulfide anions are dissolved in the repetitive charging and discharging so it makes the capacity decrease. To minimize this phenomenon, we modified ordered mesoporous carbon(OMC) materials. OMC has high thermal and chemical stability, high surface area and high pore volume. We synthesized the OMC materials with micropores by introducing silica nanoparticles and loaded metal nanoparticles on the OMC. The materials were characterized by X-ray diffraction(XRD), N2-sorption, scanning electron microscope(SEM), and energy dispersive X-ray(EDX). |
