Claim 0:
1. A sodium-ion battery comprising:
a cathode;
a non-aqueous electrolyte;
an anode; and
a separator between the cathode and the anode;
wherein:
the anode comprises a phosphorus-carbon composite comprising:
nano-sized phosphorus particles uniformly dispersed on a surface of a dual-component carbon matrix and/or pores of a dual-component carbon matrix;
the nano-sized phosphorus particles comprising black phosphorus; and
a dual-component conductive carbon matrix comprising:
a first component selected from the group consisting of graphene, reduced graphene oxide, acetylene black, carbon black, a metal-organic framework, porous carbon, carbon spheres, and carbon aerogel; and
a second component selected from the group consisting of single-walled carbon nanotubes, multi-walled carbon nanotubes, carbon nanofibers, carbon nanotube arrays, polypyrrole, and polyaniline;

the first component is present in an amount of about 1% to about 60% by weight of the phosphorus-carbon composite, and the second component is present in an amount of about 0.5% to about 30% by weight of the phosphorus-carbon composite; and
the phosphorus-carbon composite comprises the nano-sized phosphorus particles, the carbon black, and the multi-walled carbon nanotubes, and they are present in the phosphorus-carbon composite at a ratio of 7:2.5:0.5, respectively.
