Scalable 3D lithium metal anode

Abstract

A rechargeable battery device, specifically a scalable 3D lithium metal anode, and a method of manufacturing the same is disclosed. The scalable 3D electrode can serve as a lithium (Li) metal host that enables stable lithium metal cycling. Furthermore, the electrode can be fabricated by coating a slurry of well mixed LiNO3, carbon black, and PVDF on a Cu foil. For example, a 3D electrode can include a binder and a plurality of additives, wherein the plurality of additives comprise at least one conductive additive and at least one solid electrolyte interface (SEI) formation additive. The conductive additive can include electronic conductors, where the conductors are selected from a group consisting of carbon black, carbon nanotubes, carbon fibers, vapor grown carbon fiber (VGCF), graphite, and graphene. The SEI formation additives are selected from a group consisting of LiNO3, RbNO3, KNO3, CsNO3, LiFSI, LiAsF6, LiF, Li2O, Li2CO3, Li3PO4, SiO2, and Li3N.
