| Outline of Final Research Achievements |
The aim of this research project was to further develop an unprecedented way for functionalizing / resourcing sulfur. Based on the structural similarity between a high Tc superconductor model and one-dimensional sulfur chains/carbon nanotube hybrids, we had challenged to fabricate a material based on the model structure and found a plausible way to design the material using the hetero-ion insertion method. To unveil the inherent electronic properties, we have successfully developed an in situ scanning electron microscope combined with electric transport and cryogenic techniques. In addition, we found that the one-dimensional sulfur chains/carbon nanotube hybrids exhibited a good performance for the next-generation flexible lithium-sulfur microcathodes.
