The invention provides a doped multi-walled carbon nanotube. The doped multi-walled carbon nanotube comprises a multi-walled carbon nanotube and doping atoms doped in the multi-walled carbon nanotube.The doped multi-walled carbon nanotube is provided with a radial conductive channel, and the radial conductive channel is formed by covalent bonding of the doping atoms and adjacent tube walls of themulti-walled carbon nanotube. The doped multi-walled carbon nanotube has good conductivity, and the conductivity of an electrode material can be improved when the doped multi-walled carbon nanotube is applied to the electrode material. The invention further provides a preparation method of the doped multi-walled carbon nanotube. The preparation method is simple in process and convenient to operate, and the obtained doped multi-walled carbon nanotube is high in yield. 本申请提供了一种掺杂多壁碳纳米管，包括多壁碳纳米管和掺杂在多壁碳纳米管中的掺杂原子；该掺杂多壁碳纳米管具有径向导电通道，径向导电通道是由掺杂原子与多壁碳纳米管的相邻管壁通过共价键合形成。该掺杂多壁碳纳米管具有良好的导电性，将其应用在电极材料中能够提高电极材料的导电性。本申请还提供了一种掺杂多壁碳纳米管的制
