A Study on Hyper-Materials Design for High Energy Performance |
| 초록 |
Hyper-materials design for advanced energy performance and storage is one of the interesting research fields but it has still remained unsolved key issues. In this work we study three different applications of material design which are transparent heat devices, biosensor, proton exchange membrane fuel cells and lithium ion batteries. Here in our experimental range, heteroatoms doping and mixing of another chemical components are prepared by organometallic chemical vapor deposition system and plasma combined vapor deposition system, respectively. First, the hyper-conductive materials were fabricated based on atomic concentration control by employing the SnOx:M (M=Ga, Zn, Al and F) composite films in order to create the hyper conductive oxide (HCO) for heat devices (HDs) and the bipolar plates for proton exchange membrane fuel cells (PEMFCs) as well. The electrical, optical and electrochemical properties of SnOx:M films for those applications were evaluated based on their interface characteristics. In the present study, the basic theory and experimental processing are investigated for the preparation of SnOx:M films. Second, a surface morphology control for bipolar plate of PEM fuel cells was arranged as protective layer to provide a high corrosion resistance and an excellent interfacial contact resistance under high acid environment. Third, the deposition of active electrode materials is performed on the surface of copper current collector directly by using the plasma vacuum system and patterning of the electrode materials is also tried to design the interface structuring. Subsequently, investigation of surface morphological and structural properties of the doped C60 films as an anode electrode for lithium ion batteries is carried out with transmission electron microscopy (TEM) and solid state magic angle spinning/nuclear magnetic resonance (MAG/NMR).The obtained electrochemical results revealed that the micro-patterned electrode prepared by the photo-lithography synthesis is one of the useful techniques to prepare the anode material for micro-lithium-ion batteries. |
