  • Patent number: 10923726
    Abstract: An artificial solid electrolyte interphase (ASEI) of an anode for a secondary battery includes a first film composed of amino-functionalized, reduced graphene oxide (rGO) that is amino-functionalized by binding with polyethyleneimine present in an amount of from 1 to 50% by weight, based on total weight of the amino-functionalized, reduced graphene oxide (rGO) and that is disposed in contact with an anode material to protect the anode material; and a second film comprised of amino-functionalized, multi-walled carbon nanotubes that is amino-functionalized by binding with polyethyleneimine and that is stacked on the first film. An anode of a secondary battery including the ASEI enables rapid diffusion and stable deposition of lithium to inhibit the formation of dendrites. In a secondary battery including the anode, the ASEI prevents side reactions between a lithium metal anode and the electrolyte, achieving good electrochemical stability and high Coulombic efficiency.
