| 제목 | Enhanced Carbon Materials with Physical Block and Catalytic Effects for Li-S Batteries |
| 초록 | Nowadays portable electronic devices are used widely and these are indispensable part of everyday life. It makes secondary batteries important for future innovation. Li-S battery is becoming one of the promising batteries. It has high theoretical energy density and low cost. Also it is eco-friendly and safe. However, there is the primary problem to be commercialized, which is shuttle effect. It makes capacity decrease and internal resistance increase. To minimize the shuttle effect, we modified ordered mesoporous carbon(OMC) materials. OMC has high thermal and chemical stability, high surface area and high pore volume. First, we synthesized the OMC materials with micropore by introducing silica nanoparticles. We expected that polysulfides with long chain could be blocked due to the small pore size. In the second place, we loaded metal nanoparticles on the OMC. Nanoparticles of platinum could catalyze the reaction of polysulfides so dissolved polysulfides could be trapped. |
