Abstract
A sulfur-based cathode for use in an electrochemical cell is disclosed. An exemplary sulfur-based cathode is coupled with a solid polymer electrolyte instead of a conventional liquid electrolyte. The dry, solid polymer electrolyte acts as a diffusion barrier for the sulfur, thus preventing the sulfur capacity fade that occurs in conventional liquid electrolyte based cell systems. The solid polymer electrolyte further binds the sulfur-containing active particles, preventing sulfur agglomerates from forming, while still allowing lithium ions to be transported between the anode and cathode.
