Embodiment 1
[0015] First, soak 0.5 g of commercial polythiophene derivative poly3.4-dioxyethylene thiophene in 5% aqueous solution of polystyrene sulfonic acid for 1 h, take it out, and dry it at 80 ° C for 1 h, then the doped Poly 3.4-dioxyethylene thiophene is placed in the mixed solution of ethanol and naphthol, wherein the volume ratio of ethanol and naphthol is 20:1, so that the solid content of poly 3.4-dioxyethylene thiophene after doping is 20% , while adding polytetrafluoroethylene binder dropwise so that the mass fraction in the solution is 1%, and the mixed solution is ultrasonically oscillated for 30 minutes and left to stand for later use;
[0016] Secondly, fix the Pt sheet, drop a small amount of coating solution on the Pt with a dropper, disperse it evenly with a glass rod, and then take it out after drying at 80°C for 10 minutes, and repeat the operation continuously to obtain a coating with a thickness of 15 μm. energy storage electrodes;
[0017] Again, assemble the ba...
Embodiment 2
[0020] First, soak 0.3g of commercialized polyaniline in 10% hydrochloric acid for 5 hours, take it out and dry it at 90°C for 90 minutes, then place the doped polyaniline in a mixed solution of isopropanol and naphthol, in which isopropanol The volume ratio with naphthol is 15:1, so that the solid content of polyaniline after doping is 30%, and polytetrafluoroethylene binder is added dropwise at the same time, so that its mass fraction in the system is 3%, and mixed The solution was ultrasonically oscillated for 40 minutes and left to stand for later use;
[0021] Secondly, fix the Pt sheet, drop a small amount of coating solution on the Pt with a dropper, disperse it evenly with a glass rod, then dry it at 80°C for 10 minutes, take it out, and repeat the operation continuously to obtain an energy storage film with a thickness of 50 μm. electrode;
[0022] Again, assemble the battery, the electrolyte used is the electrolyte of the conventional photosensitive cell, and the ph...

[0025] First, soak 0.8g of commercial polypyrrole in 15% polystyrene sulfonic acid for 10h, take it out and dry it at 100°C for 2h, then place the doped polypyrrole in a mixed solution of isopropanol and naphthol Among them, the volume ratio of isopropanol and naphthol is 25:1, so that the solid content of the polypyrrole after doping in the whole system is 50%, and the polytetrafluoroethylene binder is added dropwise at the same time to make it in the system The mass fraction in is 5%, and the mixed solution is ultrasonically oscillated for 1 hour and left to stand for later use;
[0026] Secondly, fix the Pt sheet, drop a small amount of coating solution on the Pt with a dropper, disperse it evenly with a glass rod, then dry it at 80°C for 10 minutes, take it out, and repeat the operation continuously to obtain an energy storage film with a thickness of 100 μm. electrode;
[0027] Again, assemble the battery, the electrolyte used is the electrolyte of the conventional photo...
