More Information
Summary:The present disclosure relates to a lithium sulfur battery, and the battery includes a cathode and an anode arranged facing each other; a separator interposed between the cathode and the anode; and an electrolyte, and further includes at least one or more membranes of a lithium ion conductive polymer membrane positioned between the cathode and the separator and having a sulfonic acid group (-SO 3 H), and a metal oxide membrane positioned between the anode and the separator, and therefore, an electrode active material loss is reduced, an improved lifespan characteristic is obtained by blocking the spread of lithium polysulfide to the anode, and in addition thereto, enhanced safety is obtained by suppressing a dendrite growth in the anode.
