Examples
Example Embodiment
[0032] Example 1 1 part by weight of polyvinylidene fluoride, 98.5 parts by weight of graphite powder with an average particle size of 25 microns, and 0.5 part by weight of silane coupling agent are uniformly dispersed in a solvent (N-methylpyrrolidone) to obtain a slurry with a solid content of 5%. The slurry was dipped and coated on both sides of a corroded aluminum foil with a thickness of 50 μm, and the thickness of the carbon layer on one side was 50 μm after drying. Place the pole piece in N 2 Maintain the atmosphere at 350°C for 48h.
Example Embodiment
[0033] Example 2 Mix 6 parts by weight of polytetrafluoroethylene emulsion (water-based emulsion with 50% polytetrafluoroethylene content), 96 parts by weight of graphite powder with an average particle size of 15 microns, and 1 part by weight of titanate coupling agent in a solvent (dimethyl carbonate). ) Is uniformly dispersed to obtain a slurry with a solid content of 10%. The slurry is dipped and coated on both sides of a corroded aluminum foil with a thickness of 50 μm. After drying, the carbon layer has a single-sided thickness of 35 μm. Place the pole piece in N 2 Keep the atmosphere at 380°C for 40h.
Example Embodiment
[0034] Example 3 5 parts by weight of epoxy resin, 94.5 parts by weight of graphite with an average particle size of 20 microns and 0.5 parts by weight of titanate coupling agent are uniformly mixed and dispersed in a solvent (propylene glycol methyl ether) to obtain a slurry with a solid content of 20%. The slurry was coated on both sides of a corroded aluminum foil with a thickness of 50 μm by a knife coating method, and the thickness of the carbon layer on one side was 45 μm after drying. Place the pole piece in N 2 Keep the atmosphere at 400°C for 36h.
