▎ 摘  要

NOVELTY - A battery comprises a cathode, an anode positioned opposite the cathode, a hybrid artificial solid-electrolyte interphase (A-SEI) layer deposited on the anode and including active components, a blended material interwoven throughout the active components and configured to inhibit growth of lithium dendritic structures from the anode to the cathode, where the blended material comprises a combination of crystalline sp2-bound carbon domains of graphene sheets and flexible wrinkle areas positioned at joinder points of two of more of the crystalline sp2-bound carbon domains of graphene sheets, a polymeric matrix configured to bind the active components and the blended material together, an electrolyte in contact with the hybrid A-SEI and the cathode, and a separator positioned between the electrodes. USE - Battery such as lithium-ion battery, lithium-sulfur battery and lithium-metal battery. Uses include but are not limited to electric vehicle, hybrid electric vehicle, modern portable electronic devices such as laptop computers and smartphones, and microelectonic devices. ADVANTAGE - The battery has improved cycle life characteristics. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating reduction of sulfur and/or the formation of polysulfides. Polysulfide compounds (100F)
