Lithium-sulfur 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 cycles and it makes the capacity decrease. To suppress this phenomenon, we synthesized carbon materials. Ordered mesoporous carbon (OMC) has high thermal and chemical stability, high surface area and high pore volume. We synthesized the OMC materials with nanopores 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(EDS). |
