Abstract
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.
下一代硫基电池的阳极和阴极改性的进展已成为一个突出的研究热点。本研究介绍了一种通过一步水热法设计和合成硅/石墨烯纳米板（Si/GNPs）的方法。此外，我们建议纳米复合碳掺杂ZnO/S作为潜在的阴极材料，通过尿素辅助醋酸锌的热分解。C/ZnO/S具有减缓电解质体积变化和阻碍硫溶解的特殊能力。此外，ZnO在ZnO/S复合材料中具有优越的硫分布，并增强了硫转化反应。这种电池的配置是第一次被提及，并且在500次循环后显示出916 mAh g-1的杰出保持容量，表明每个循环的最小衰减率仅为0.047%。
