| 제목 | Synthesis of ZnIn2S4/C nanocomposites and electrochemical properties as anode material for lithium ion battery |
| 초록 | Lithium ion batteries (LIB) are effective electrochemical energy storage device. Graphite is the most commonly used anode for LIB, however, low theoretical capacity is its disadvantage. To overcome this limitation, the development of high-capacity anode material is indispensable. Layered ternary chalcogenide system, Zinc Indium Sulfide (ZnIn2S4) exhibits two polymorphs based on cubic and hexagonal lattices. In2S3 has a layered structure with proven high theoretical capacity and ZnS has reversible lithium insertion/desertion with good stability. On the other hand, ordered mesoporous carbons could be a reliable framework with acceptable conductivity. From these features, composite of carbon and ZnIn2S4 could be a good anode material for LIB. In this work, ZnIn2S4/C nanocomposites are synthesized with CMK-3 and tested for anode material in lithium ion battery. Characterization methods are X-ray diffraction, Nitrogen sorption, SEM, and various electrochemical investigations. |
