Aluminum electrolysis anode and preparation method thereof
The invention relates to an aluminum electrolysis anode. The aluminum electrolysis anode comprises a graphite base body, the corrosion-resistant layer is arranged on the surface of the graphite substrate, and the material of the corrosion-resistant layer comprises graphene. According to the aluminum electrolysis anode provided by the invention, the corrosion-resistant layer is arranged on the surface of the graphite substrate, and the corrosion-resistant layer protects the surfaces of the graphite particles, so that the corrosion resistance and the oxidation resistance of the aluminum electrolysis anode can be remarkably improved. Therefore, the aluminum electrolysis anode has good corrosion resistance and oxidation resistance. Meanwhile, due to the fact that the material of the corrosion-resistant layer comprises graphene, the corrosion-resistant layer also has good electrical conductivity, and therefore corrosion resistance, oxidation resistance and electrical conductivity of the aluminum electrolysis anode are considered at the same time.
本申请涉及一种铝电解阳极，所述铝电解阳极包括：石墨基体；设置在所述石墨基体表面的耐腐蚀层，所述耐腐蚀层的材料包括石墨烯。本申请提供的铝电解阳极，通过在所述石墨基体表面设置一层耐腐蚀层，所述耐腐蚀层对石墨颗粒表面形成保护，可显著提高铝电解阳极的耐腐蚀性、抗氧化性。这使得所述铝电解阳极具有良好的耐腐蚀性、抗氧化性。同时，由于所述耐腐蚀层的材料包括石墨烯，使得所述耐腐蚀层也具备较好的导电性，因此本申请实现了铝电解阳极耐腐蚀性、抗氧化性和导电性的兼顾。
