| Research Abstract |
The development of carbon-sulfur composite is important for lithium-sulfur secondary batteries. In this study, carbons for lithium-sulfur batteries were prepared using SPS apparatus. The carbon-sulfur composite electrodes were prepared by a mechanical milling process. The composite prepared by long time milling shows the reversible capacity of ca. 500 mAh g-1. The sulfur component of the composite was hardly soluble into the ether-based electrolyte. The composite electrodes for all-solid-state batteries were prepared by the mechanical milling of the mixture of sulfur, carbon, and solid electrolytes.
