Abstract
A battery electrode composition is provided comprising core-shell composites. Each of the composites may comprise a sulfur-based core and a multi-functional shell. The sulfur-based core is provided to electrochemically react with metal ions during battery operation to store the metal ions in the form of a corresponding metal-sulfide during discharging or charging of the battery and to release the metal ions from the corresponding metal-sulfide during charging or discharging of the battery. The multi-functional shell at least partially encases the sulfur-based core and is formed from a material that is (i) substantially permeable to the metal ions of the corresponding metal-sulfide and (ii) substantially impermeable to electrolyte solvent molecules and metal polysulfides.
