This invention relates to the field of carbon-based anode materials for lithium-ion batteries, specifically disclosing a carbon-based fiber electrode and its preparation method. The method involves ion implantation of Ir into the surface of graphite felt fiber material. Metallic Ir not only improves the electrochemical activity of the carbon-based electrode but also serves as a catalyst for the subsequent ALD (Alternating Discharge) process to prepare carbon nanotubes.
