Described is a lithium-sulfur electrochemical cell in which the anode and the cathode are each equipped with a respective solid-electrolyte interphase (SEI) layer that inhibits lithium side reactions. On the cathode side, the SEI layer inhibits the shuttle...

A method for preparing an aqueous cathode slurry composition, specifically including: (a) performing a first mixing step by mixing a binder and an aqueous solvent; and (b) mixing lithium iron phosphate (LiFePO) as the cathode active material and a conducti...
