1. A compound comprising:
a plurality of carbon nanotubes (CNTs); and
a nanowire of a metal sulfide respectively filled in each CNT,
an average filling ratio, across all of the CNTs present in the compound, of the metal sulfide being at least 0.90,
the CNTs having an average length of at least 5 μm,
each CNT filled with the respective nanowire being straight from a first end thereof to a second end thereof, and
the first end and the second end of each CNT filled with the respective nanowire being closed with carbon shells.
