Özet:

 It is of great importance to develop high-performance energy storage systems that modern society needs for next-generation technologies such as electric vehicles, consumer electronics, and grid-scale storage. Lithium-sulfur Li-S batteries are one of the promising candidates for high-performance energy storage systems due to the high theoretical capacity of the sulfur. On the other hand, some drawbacks such as insulating nature of the sulfur and the polysulfide solubility limits the wide-spread application of Li-S batteries. Nanocomposite host materials with high surface area and conductive nature has a potential to improve the stability of sulfur cathodes. In this study, the MOF-derived heteroatom doped carbon cZIF-67 and two dimensional Ti3C2 MXene materials were used to fabricated cZIF-67Ti3C2 nanocomposites. The fabricated nanocomposites were used as sulfur host material for Li-S batteries. After the structural and chemical characterizations, ScZIF-67Ti3C2 nanocomposite cathodes were used in Li-S batteries, and their performance-related properties were examined. With the fabricated ScZIF-67Ti3C2 cathodes, the adverse effects caused by the insulating nature of sulfur and lithium polysulfides are eliminated.

 Modern toplumun elektrikli araçlar, tüketici elektroniği ve şebeke tipi depolama gibi yeni nesil teknolojiler için ihtiyaç duyduğu yüksek perform2anslı enerji depolama sistemlerinin geliştirilmesi büyük önem taşıyor. Lityum-sülfür Li-S bataryalar, kükürtün yüksek teorik kapasitesi nedeniyle yüksek performanslı enerji depolama sistemleri için umut verici adaylardan biridir. Öte yandan kükürtün yalıtkan doğası ve polisülfit çözünürlüğü gibi bazı dezavantajlar Li-S bataryaların geniş çaptaki uygulamasını sınırlamaktadır. Yüksek yüzey alanına ve iletken doğaya sahip nanokompozit konak malzemeler, kükürt katotlarının stabilitesini iyileştirme potansiyeline sahiptir. Bu çalışmada, MOFtan türetilmiş heteroatom katkılı karbon cZIF-67 ve iki boyutlu Ti3C2 MXene malzemeler kullanılarak cZIF-67Ti3C2 nanokompozitleri üretilmiştir. Üretilen nanokompozitler Li-S bataryalar için kükürt tutucu malzeme olarak kullanıldı. Yapısal ve kimyasal karakterizasyonların ardından ScZIF-67Ti3C2 nanokompozit katotlar Li-S bataryalarda kullanılarak performans ilintili özellikleri incelenmiştir. Üretilen ScZIF-67Ti3C2 katotlar ile kükürtün yalıtkan yapısından ve lityum polisülfitlerden kaynaklanan olumsuz etkiler ortadan kaldırılmıştır.
