SEOUL, April 7 (Korea Bizwire) – Korean scientists have developed a super capacitor material which can charge electricity 10 times faster than existing batteries, and store twice as much as graphene-based materials.
Professor Park Ho-seok of the School of Chemical Engineering at Sungkyunkwan University, announced that his team created the super capacitor material by making 2D nanosheets of inorganic composition made of transitional metal and sulfur, and laying the nanosheets one by one in a 3D structure. The study was posted at Nano Letters on March 3.
The research team grafted nanotechnology to existing layered compositions, accelerating the expansion of ions and the movement of electric charges to finally develop the high power and high capacity supercapacitor.
To this end, the research team formed the nano-sized layered inorganic composition by peeling graphite like obtaining graphene and synthesized the 3D structure by layering the sheets. The 3D nano structure has a higher efficiency in terms of the expansion of ions and the movement of electric charges by exposing the 2D nanosheets without overlay.
Professor Park said, “Although it is expected to take about 10 years to commercialize, the technology will facilitate the development of ultra-super capacitor materials utilized in next generation energy industries such as electric vehicles and smart grids.”
