BATTERIES INCORPORATING GRAPHENE MEMBRANES FOR EXTENDING THE CYCLE-LIFE OF LITHIUM-ION BATTERIES

摘要

Embodiments of the present invention relate to energy storage devices and associated methods of manufacture. In one embodiment, an energy storage device comprises an electrolyte. An anode is at least partially exposed to the electrolyte. A selectively permeable membrane comprising a graphene-based material is positioned proximate to the anode. The selectively permeable membrane reduces a quantity of a component that is included in the electrolyte from contacting the anode and thereby reduces degradation of the anode.
