Embodiment 1
[0020] The clean nickel sheet is evenly coated with the cellulose acetate film casting solution containing carbon nanotubes, so that a microfiltration membrane with uniform pore size can be formed on the nickel sheet. The casting solution is the membrane material - the polymer compound is dissolved in a good solvent, and the porogen is added to form a microfiltration membrane polymer solution under certain conditions.
[0021] Put the nickel sheet after the above treatment into 0.1mol / L potassium permanganate solution, make the potassium permanganate solution permeate and adsorb on the inner wall of the microfiltration membrane, and then treat it at a high temperature of 200°C for 30 minutes to obtain an oriented tubular array Structure of manganese dioxide.
[0022] Treat the above-mentioned nickel sheet in a nitrogen atmosphere at a high temperature of 400°C for 50 minutes, and let it cool down to room temperature naturally after the high-temperature treatment to obtain a ma...
Embodiment 2
[0025] The clean titanium sheet is evenly coated with the polysulfone casting solution containing carbon nanotubes, so that a polysulfone microfiltration membrane with uniform pore size can be formed on the titanium sheet.
[0026] Put the above treated titanium sheet into 1mol / L potassium permanganate solution, make the potassium permanganate solution infiltrate and adsorb on the inner wall of the polysulfone microfiltration membrane, and then treat it at 250°C for 90 minutes to obtain oriented tubular Array structure of manganese dioxide.
[0027] Put the treated titanium sheet in an argon atmosphere at a high temperature of 500°C for 60 minutes, and let it cool down to room temperature naturally after the high temperature treatment to obtain a manganese dioxide / carbon nanotube / carbon composite electrode material.
