THIN FILM SULFUR-COATED CONDUCTIVE CARBON, POSITIVE ELECTRODE MIXTURE AND ALL-SOLID-STATE LITHIUM SULFUR BATTERY

摘要

PROBLEM TO BE SOLVED: To provide thin film sulfur-coated conductive carbon which can be used suitably in the positive electrode mixture of an all-solid-state lithium sulfur battery having excellent discharge capacity and rate characteristics, by making the most of the excellent physical properties of sulfur.SOLUTION: The thin film sulfur-coated conductive carbon is conductive carbon having the surface coated with a sulfur film. The conductive carbon has BET specific surface area of 500 m/g or more, and the sulfur film has a thickness of 0.4-5.0 nm. The thin film sulfur-coated conductive carbon is used in the positive electrode mixture of an all-solid-state lithium sulfur battery.
