  • Patent number: 11978846
    Abstract: A solid electrolyte membrane for a solid-state battery and a battery comprising the same is provided. The battery may comprise lithium metal as a negative electrode active material. The solid electrolyte membrane comprises an inhibiting layer, which is preferably capable of inhibiting growth of lithium dendrite, because it includes an effective amount of a dendrite growth-inhibiting material, which is capable of ionizing lithium deposited in the form of metal. Thus, when lithium metal is used as a negative electrode for a solid-state battery comprising the solid electrolyte membrane, it is possible to delay and/or inhibit growth of lithium dendrite, and thus to effectively prevent an electrical short-circuit caused by dendrite growth.
