NOVELTY - Preparation of negative electrode grid alloy of lead-carbon battery, involves adding ultrafine graphite and graphene to reactor in sequence, adding pure lead or pure lead particles, covering uppermost layer of added raw material with sodium chloride, controlling temperature to 500-800 degrees C, shaking or stirring for 1 hour, continuing to warm to 800-1100 degrees C, shaking or stirring for 1 hour, warming to 1050-1150 degrees C, shaking or stirring for 3 hours obtaining an alloy liquid, cooling alloy liquid, pouring into ingot mold, cooling to room temperature, placing obtained alloy ingot in water and soaking for 1 hour, taking out and drying. USE - Preparation of negative electrode grid alloy of lead-carbon battery. ADVANTAGE - The grid forms excellent combination with lead-carbon paste of negative electrode, has excellent grid strength, high hardness and excellent corrosion resistance, and can be directly coated ensuring continuous casting and continuous coating and convenient processing.
