A LITHIUM SULFUR BATTERY COMPRISING ELECTRODE SEALED BY FILM

摘要

The present invention relates to a battery structure with an electrode completely sealed by replacing a separation film used in a lithium sulfur secondary battery with a lithium ions selectively permeable film, forming an adhesive layer on the both edges of the film, and thermosetting the adhesive layer. A lithium sulfur secondary battery comprising a sealing electrode of the present invention inhibits movement of an active material melted and came out as an electrolyte, and thus lowering irreversible capacity and increasing durability of a battery.
