Abstract:
The present disclosure relates to a method for production of nitrogen-doped single wall carbon nanohorns from anode graphite of wasted lithium-ion batteries. The method includes the following steps: a first step: forming recycled graphite powder into graphite blocks; and, a second contact step: when the first step is completed, using a DC arc plasma device to produce the graphite blocks into N-SWCNHs.
