摘要:
The present invention relates to a solid composite for use in the cathode of a lithium- sulphur electric current producing cell wherein the solid composite comprises 1 to 75 wt.-% of expanded graphite, 25 to 99 wt.-% of sulphur, 0 to 50 wt.-% of one or more further conductive agents other than expanded graphite, and 0 to 50 wt.-% one or more binder, based on the total amount of the solid composite, a lithium-sulphur electric current producing cell comprising (i) a cathode comprising the solid composite, (ii) an anode and (iii) an electrolyte interposed between said cathode and said anode, and a process for preparing the solid composite comprising the steps (I) preparing a slurry comprising sulphur, expanded graphite, and optionally further components in a liquid medium by dispersing the sulphur, the expanded graphite, and optionally the further components in the liquid medium; (II) casting the slurry provided in step (I) on a substrate or placing the slurry provided in step (I) into a mold; and (III) removing some or all of the liquid medium from the slurry cast in step (I I) to form a solid composite.
