1. A method of producing a nickel nanopowder, the method comprising:
providing a nickel salt and a shell-forming material;
nucleating and growing nickel core particles from the nickel salt;
forming a shell layer on surfaces of the nickel core particles using the shell-forming material; and
removing the shell layer to form the nickel nanopowder,
wherein, in the forming, a free energy of formation of the shell-forming material is smaller than a free energy of formation of the nickel salt.
