| Outline of Final Research Achievements |
In this research, we elucidated the mechanism of PVDF dehydrofluorination reaction and clarified the generation process of activated carbon by changing the manufacturing conditions in a hybrid electrode material consisting of PVDF/potassium carbonate. Accordingly, to achieve the best material performance, the manufacturing procedure was well investigated and an optimized synthesis process was found. Based on that, further enhancement of electrochemical performance could be achieved by the addition of transition metal (Co&Ni) oxides, and the supercapacitor assembled with the developed carbon hybrid composite electrode material showed superior performance.
As the research results, two papers have been published in international journals, one paper currently submitted, and another manuscript in preparation. The research contents were also presented at several national and international conferences.
