Embodiment 1
[0014] (1) Add 1g of carbon nanotubes with a diameter of 20nm and a length of 1um, 1g of graphene, and 1g of polyacrylonitrile to 100mL of N-methylpyrrolidone, stir evenly and ultrasonically react for 30 minutes, and then coat the mixed slurry on aluminum foil , and vacuum-dried to obtain electrode sheets.
[0015] (2) Put the obtained electrode sheet into an inert gas-protected muffle furnace, slowly raise the temperature to 400°C at a rate of 3°C / min, react for 60 minutes, and cool naturally.
[0016] (3) Completely insert the electrode sheet obtained in (2) into 2mol / L Na 2 S 2 o 3 In the solution, stand still for 30 minutes, then slowly add 1mol / L hydrochloric acid dropwise to the solution until the solution pH=6.5, take out the electrode sheet, and obtain the positive electrode sheet after drying.
