More Information
Summary:The invention discloses a pretreatment method for a carbon-based electrode material of an electrochemical system, which belongs to the technical field of carbon-based electrode materials. The pretreatment method comprises the following steps of soaking the carbon-based electrode material in an organic solvent for 1-10 hours, carrying out acid pickling and first cleaning to obtain a clean carbon-based electrode material, then soaking the clean carbon-based electrode material in a nitric acid solution, and carrying out heating treatment for 5-7 hours, after secondary cleaning, obtaining an activated carbon-based electrode material, uniformly dispersing potassium permanganate, oxalic acid and polyethylene glycol in an aqueous solution, heating and stirring at 20-30 DEG C for 30-50 min, cooling, adding potassium manganate, uniformly mixing, immersing the activated carbon-based electrode material, carrying out a hydrothermal reaction at 120-160 DEG C for 8-16 h, cooling, washing with the aqueous solution, and airi
