Disclosed are a carbon dioxide absorbent composition in which an N-alkylaminoalkanol; a polyhydroxyamine-based compound; and ethylenediamine and/or diethylenetriamine are mixed, a method for preparing the same, and a method and an apparatus for carbon dioxide absorption/separation using the same. Since the carbon dioxide absorbent according to the present disclosure has superior carbon dioxide absorption capacity and remarkably lower absorbent recycling temperature as compared to the existing absorbents such as monoethanolamine, etc., total energy consumption in the capturing process can be reduced greatly. In addition, since carbon dioxide is recovered at low recycling temperature, contamination by water or absorbent vapor may be prevented.

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.
