Aluminum electrolysis anode and preparation method thereof
The invention relates to an aluminum electrolysis anode, the material of the aluminum electrolysis anode comprises carbon-based particles coated with a corrosion-resistant layer, the material of the carbon-based particles comprises graphite, and the material of the corrosion-resistant layer comprises graphene. According to the aluminum electrolysis anode, the corrosion-resistant layer is arranged on the surface of the carbon-based particle, the corrosion-resistant layer protects the graphite surface in the carbon-based particle, and 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，所述铝电解阳极的材料包括耐腐蚀层包覆的碳基颗粒，所述碳基颗粒的材料包括石墨，所述耐腐蚀层的材料包括石墨烯。本申请通过在所述碳基颗粒表面设置一层耐腐蚀层，所述耐腐蚀层对碳基颗粒中的石墨表面形成保护，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。
