1. A method of making turbostratic carbon, comprising:
forming a suspension by suspending the turbostratic carbon in a polar liquid solvent;
aerosolizing the suspension; and
drying the aerosolized suspension to force the suspended turbostratic carbon into intimate contact to form a hollow envelope,
wherein the turbostratic carbon comprises:
a D band having a peak intensity (ID) at wave number between 1330 cm-1 and 1360 cm-1;
a G band having a peak intensity (IG); and
a 2D band having a peak intensity (I2D) at wave number between 2650 cm-1 and 2750 cm-1.
