在這一世代，因為科技快速地發展，環境友善的議題隨之增加，儲能裝置的重要性以及需求亦隨之提高。
本研究有關鋰硫電池，鋰硫電池為下一世代最有前景的儲能材料之一，因為其高能量密度以及硫的經濟實惠價格。然而，因為硫有不佳的電子導電度而絕緣，所以活性硫利用不佳，其中間產物長鏈鋰硫化合物易溶於電解液當中，造成活性物質的流失，阻抗提升，電容量降低。
為解決這些問題，我們利用ZnS為前驅物，將銳鈦礦TiO2和碳披覆在表面上，最後利用Fe3+離子氧化S2-離子，合成出S/TiO2/C之殼層結構。TiO2/C殼層兼具物理阻隔以及化學方式吸附鋰硫化合物，而石墨化碳殼層進而提升導電能力。
當ZnS/TEOTi的莫耳比為15時，S/TiO2的硫重有77 %，其第一百圈之電容量為733 mAh g-1 (0.5 C)，比奈米商用硫第一百圈電容量560 mAhg-1(0.5 C)來的高。最佳化的S/TiO2/C陰極材料其硫重56.8 wt%、石墨化碳重18.3 wt%，由ZnS/TiO2/C製備而成而碳來源重14 wt%，一百圈充放電過後依然保持905 mAhg-1(0.5 C)，且阻抗最低。

In this generation, the importance of and the demands from the energy storage devices are much more than before because of the environmentally friendly issue arising with the technology developing.
This investigation revealed the lithium sulfur battery which is one of the most promising energy storage materials in the next generation due to high energy density and economic price of the sulfur. Nevertheless, the sulfur which has poor electron conductivity was insulated, so the active sulfur was not fully utilized. The intermediate, long chain lithium sulfide can easily dissolve into electrolyte; as a result, the active material lost, resistance increased and capacity decayed.
In order to solve these problems, we fabricated ZnS as the precursor, then we coated anatase TiO2 and carbon on the surface. Finally, S2- ions were oxidized by Fe3+ ions to form S/TiO2/C structure. The TiO2/C shell combined the advantages of physically separating particles, chemical trapping the lithium sulfide, while graphic carbon provided improved electronic conductivity.
When the molar ratio of ZnS/TEOTi was 15, the sulfur weight percent of S/TiO2 was 77 %. The capacity of S/TiO2 was 733 mAhg-1 (0.5 C) at 100th cycle. The capacity of S/TiO2 was higher than the capacity of commercial nano sulfur which was 560 mAhg-1 (0.5 C) at 100th cycle. The optimized S/TiO2/C cathode material which had 56.8 wt% sulfur and 18.3 wt% graphic carbon was made from ZnS/TiO2/C and still maintained the capacity at 905 mAhg-1 (0.5 C) after 100 cycles and had the lowest resistance when the carbon source was 14 wt%.
