Abstract

A rechargeable lithium battery includes a lithium anode, a cathode, and a separator interposed between the lithium anode and the cathode. The separator includes a porous polymer soaked with a liquid electrolyte. The lithium battery further includes an artificial solid electrolyte interphase membrane interposed between the lithium anode and the separator. The artificial solid electrolyte interphase membrane may be a composite of a carbonaceous material, a high shear modulus conducting polymer, and a conductive additive.
