摘要
The present disclosure provides the synthesis technology for sulfur-carbon nanocomposite, which was achieved by ultrasonification to allow formation of homogeneously distributed S nanoparticles on C. Sulfur is uniformly distributed with mesoporous “functionalized carbon” to produce S—C nano-link was verified by HRTEM (FIG. 1, and 2), The discloser also reveals the performance of the EC cell assembled using S—C nanocomposite cathode in Li—S battery (FIG. 12) with capacity 910 mAh/g at low current density without fading up to 80 cycles with different C-rate. Our synthesis process is cost effective and scalable for large quantity of C—S nano-composites.
