This invention discloses a method for preparing a seawater-resistant, chlorine-doped carbon-based electrode material with five-membered ring defects. The method includes step one: mixing the chlorine-doped system; step two: pyrolysis activation treatment; step three: cooling and washing; and step four: rewashing and drying. This invention utilizes the synergistic construction of chlorine doping and five-membered ring defects. The localized negative charge induced by chlorine doping enhances its resistance to chloride ions in seawater, significantly improving the material's stability and service life in a seawater environment. The five-membered ring defects significantly improve the electronic structure and catalytic activity of the carbon material, thereby enhancing its electrocatalytic performance and improving the overall electrochemical performance of the carbon-based electrode material. The introduction of chlorine doping during the preparation process also serves as a template to promote the construction of porous nanosheet structures in the carbon material. The method is simple to operate, low in cost, and suitable for large-scale production. It balances structural innovation, superior performance, and process feasibility, possessing broad industrial prospects and technological promotion value.
