'New material of dream' Phospholin, energy storage device Applicability
-International Journals Nature Materials December 10th Publication-
Professor Park Ho-Seok of the Chemical Engineering / Polymer Science and Engineering Department said that the new energy storage mechanism of phosphorane has been identified. The team has demonstrated the feasibility of implementing two-dimensional phosphorylation as an energy storage device through nanostructuring and chemical surface control. Removing black phosporus to a layer thickness of an atom results in phosporene, which is one-tenth of the hair's thickness. Graphene and atomic arrays are similar, but unlike graphene, there is a bandgap (energy level difference) that makes it easier to control the current.
The team succeeded in identifying the supercapacitor mechanism of two-dimensional phospholin with two-dimensional nanomaterial synthesis technology and ion-behavior real-time observation technology. Super capacitor is a device that stores energy mainly by physical or surface oxidation / reduction reaction on electrode surface.
The researchers have demonstrated through spectroscopy and theoretical calculations that they precisely control the oxidation state of two-dimensional phospholines and show behavior similar to supercapacitors rather than conventional battery behaviors.
This research was carried out with the support of the radiation technology development project of the Ministry of Science and Technology, the Korea Research Foundation, and the energy technology development project of the Ministry of Commerce, Industry and Energy. The results of the study were published online in the December 10 issue of Nature Materials, an international journals in the field of materials.
