    摘要: 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.

    摘要: Systems and methods are disclosed for a battery that includes an anode, a separator between the anode and the cathode, a cathode, and a membrane coupled to the separator having a mixed electronic conductor and ionic conductor. A method may include casting a membrane onto a surface, dispersing carbon nanotubes in acetone to form a dispersion, adding a powder and dibutyl phthalate to the dispersion to form a polymer, and mixing the polymer. Another method may include casting a sheet of a composite, removing the sheet, and rinsing the sheet. Another method may further include casting a film, evaporating to form a dry film, and casting a mixture onto the dry film to form a bilayer membrane. Another method may further include casting a cathode, casting a CNT mixture onto the cathode, evaporating the cathode, and rinsing the cathode in ether.

    摘要: Disclosed is a sulfide-containing solid electrolyte material with an organic coating, as well as densified pellets containing this solid electrolyte material, a solid electrolyte thereof, and a solid state battery containing the solid electrolyte. According to aspects of the disclosure, the coating comprising a compound of Chemical Formula (1) or Chemical Formula (2) is formed on the surface of a sulfide-containing solid electrolyte material, e.g., the organic coating may comprise a compound having a thiol with a long hydrophobic tail, such as 1-undecanethiol. The coating provides densification of sulfide-containing solid electrolyte materials, and facilitates the ionic and lithium atomic diffusion coefficient at sulfide grain boundaries during pressing, thus achieving the densification of sulfide solid state electrolyte.
