Abstract
With the rapid development of portable devices and Energy Storage Systems (ESS), secondary batteries with high energy density and high capacity are in great demand. Among various candidates, Lithium-sulfur (Li-S) batteries have been considered for next-generation energy devices given their high theoretical capacity (1675 mAh g -1) and energy density (2500.....

Korean J. Met. Mater. 2017;55(7):503-508. Published online 2017 Jul 4 DOI: https://doi.org/10.3365/KJMM.2017.55.7.503
Abstract
All-solid-state Li-S batteries were fabricated with lithium silicide anodes (Li 4. 4Si), sulfide-based glass electrolyte (Li 2S-P 2S 5), and a sulfur composite cathode. The sulfur based composite cathode was prepared using two methods; (Case 1) mortar-mixing and (Case 2) planetary ball milling at a rotation speed of 370 rev/min for 15 min. SEM analysis..... More
