Secondary batteries are becoming important with increased use of portable electronic devices. Li-ion battery is the most commonly used but it shows the limitation of capacity for electric vehicle. Li-S battery is 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, which is called shuttle effect. To minimize shuttle effect, we synthesized carbon materials with porosity and metal nanoparticles. Ordered mesoporous carbon(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 as the catalytic factor. The materials were characterized by X-ray diffraction(XRD), N2-sorption, scanning electron microscope(SEM), and energy dispersive X-ray(EDX). |
