ELECTROLYTE LIQUID FOR LITHIUM-SULFUR CELL, AND LITHIUM- SULFUR CELL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electrolyte liquid for lithium-sulfur cell with excellent life characteristics and capacity characteristics, and to provide a lithium-sulfur cell containing the same. SOLUTION: Sulfur simple substance by 60%, super-P conductive agent by 20%, and poly (vinylacetate) by 20% are mixed in acetonitrile solvent, and the above slurry is coated on an Al current collector on which, carbon is coated, and dried in vacuum. A proper volume of sulfolane/toluene (40/50) electrolyte liquid containing LiSO3CF3 by 1M is dropped on a positive pole plate, and a separator is put on the above, and after adding the electrolyte liquid further, a lithium electrode is put on the above.
