1. A method for producing a carbon nanomaterial (CNM) product, the method comprising steps of:
a. heating an electrolyte media to obtain a molten electrolyte media;
b. adding at least 0.8 wt % of a nickel-containing additive to the electrolyte media or the molten electrolyte media;
c. positioning the molten electrolyte media between a high-nickel content anode and a cathode of an electrolytic cell;
d. introducing a source of carbon into the electrolytic cell;
e. applying an electric current to the cathode and the anode in the electrolytic cell; and
f. collecting the CNM product from the cathode, wherein the CNM product comprises a minimal relative-amount of at least 70 wt %, as compared to a total weight of the CNM product, of hollow nano-onion product,
wherein the high-nickel content anode is made of pure nickel or an alloy that comprises greater than 50 wt % nickel.
