Multilayered Sulfur Composite Cathodes for Lithium Sulfur Batteries

摘要

A multilayered cathode for a lithium sulfur battery comprising at least one current collector working electrode having a surface comprising a carbon containing layer, two or more sulfur containing layers wherein at least one of the sulfur layers is located in juxtaposition to and in communication with the carbon containing layer, and at least one outermost layer comprising a positively charged polymer for forming interconnected layers of the sulfur containing layer, the carbon containing layer, and the polymer. Preferably, the cathode has layers that are alternatively arranged of two or more different sulfur containing layers. A lithium sulfur battery is provided and a method of making a multilayered cathode for a lithium sulfur battery is disclosed.
