| 제목 | Synthesis of Ordered Mesoporous Carbon with Micropores and Platinum Nanoparticles for Li-S batteries |
| 초록 | Li-ion battery which is most commonly used has problems with low capacity, high price and possibility of explosion. Lithium sulfur battery is becoming a one of the promising alternatives. It has high theoretical energy density and low cost. Furthermore, it is eco-friendly and safe. But polysulfide anions are dissolved in the repetitive charging and discharging so it makes the capacity decrease, which is shuttle effect. To minimize the shuttle effect, we modified ordered mesoporous carbon(OMC) materials. Carbon materials which have good conductivity are used with sulfur because the sulfur is non-conductive. Especially the OMC has thermal and chemical stability, high surface area and high pore volume. First, we synthesized the OMC materials with micropores by introducing silica nanoparticles. We expected that polysulfides with long chain could be blocked because of the small pore size. Also we loaded platinum nanoparticles on the OMC. Platinum nanoparticles could catalyze the reaction of polysulfides so shuttle effect could be alleviated. |
