SULFUR CATHODE OF LITHIUM SULFUR BATTERIES AND METHOD OF MANUFACTURING THE SAME

摘要

The present invention provides a lithium sulfur battery with improved life characteristics and enhanced battery capacity. Particularly, a cathode for the lithium sulfur battery may include two types of binders which are different in solvents systems and adhesion types.

主权项

1. A cathode composition of a lithium sulfur secondary battery comprising:
a sulfur; a conductive material; a non-aqueous planar contact binder; and an aqueous point contact binder, wherein a planar contact is made with or comprises the sulfur or the conductive material in a planar phase, and a point contact is made with or comprises the sulfur or the conductive material in a point phase.
