Integration of Carbon-Doped ZnO/S Cathode and Silicon/Graphene Nanoplate Anode for Silicon-Sulfur Batteries

The advancement of modified anodes and cathodes for the next generation of sulfur-based batteries has become a prominent focus of research. This study introduces a methodology for the design and synthesis of silicon/graphene nanoplates (Si/GNPs) through a one-step hydrothermal process. Additionally, we suggest nanocomposite carbon-doped ZnO/S as a potential cathode material through the urea-assisted thermal decomposition of zinc acetate. C/ZnO/S has the special capability to alleviate volume change and hinder sulfur dissolution of the electrolyte. Additionally, ZnO possesses a superior distribution of sulfur in the ZnO/S composite and enhanced sulfur conversion reactions. This configuration of the cell is mentioned for the first time and shows an outstanding retention capacity of 916 mAh g^-1 after 500 cycles, indicating a minimal decay rate of merely 0.047% per cycle.
