1. A nanocomposite comprising:
one or more 2D layers of a carbon material;
one or more 2D layers of hexagonal boron nitride material; and
sulfur,
wherein sulfur makes up between 40% and 90% by weight of the nanocomposite,
wherein a weight ratio of the carbon material to the hexagonal boron nitride material is between 1:99 and 99:1, and
wherein the nanocomposite is characterized in that the nanocomposite is thermally stable at a temperature of about 100° C. to about 450° C., as measured by the thermogravimetric analysis.
