| titleOfInvention | A kind of supercapacitor electrode material and preparation method thereof |
| abstract | The invention discloses a supercapacitor electrode material and a preparation method thereof. The preparation of the electrode material comprises the following steps: the first step: in a nitrogen atmosphere, 2,4,6-tris(4-bromophenyl)-1,3 , 5-triazine and thiophene-2,5-diboronic acid dipinacol ester are reacted and polymerized under alkaline conditions and catalyst action, and the product obtains porous polymer after suction filtration, washing and vacuum drying; Second step: Carbonization: Put the porous polymer prepared in the first step into a porcelain boat, then transfer it to a tube furnace filled with nitrogen, heat it up to 800-1000°C, keep the temperature for 1-1.5h, and cool it to room temperature to obtain a supercapacitor electrode Material; the measured specific surface area of the electrode material is 1248m 2 /g, which is used in supercapacitors. Under the current density of 1.0A/g, the electrolyte solution used is 6M potassium hydroxide solution, and the measured specific capacitance is 357.0F/g And the supercapacitor electrode material after more than 10,000 cycles in 6M potassium hydroxide solution, the capacitance retention rate is 97.3%, with excellent electrochemical performance. |
