Abstract
A battery comprising a cathode and the anode compartments can be completely isolated from each other and thus preventing migration of soluble polysulfide anions from cathode to anode compartment by a novel cell design that involves enclosing either or both the cathode or the anode in sealed cation exchange polymer pouch prior to stacking and assembling the pouch cell.
