AI Technical Summary
Technical Problem
The PE separators in waste lead-acid batteries are not fully recycled, resulting in resource waste and environmental pollution, and the processing cost is high.
Method used
High-purity silica powder is obtained by cleaning, drying, calcining and pulverizing PE separators. This powder can be used as an additive for lead paste in lead-acid batteries, avoiding the need for a special impurity removal process for lead in silica.
Benefits of technology
This enables the complete recycling of PE separators, reducing environmental pollution, lowering production costs, and improving battery performance.

Abstract
本发明属于铅酸蓄电池技术领域，具体涉及一种废旧铅酸蓄电池隔板回收利用方法。将废旧铅酸蓄电池破碎、分选后得到的PE隔板使用自来水清洗，将清洗后PE隔板进行干燥至隔板含水率≤5%；干燥后的PE隔板经高温灼烧得到以二氧化硅为主成分的灼烧剩余物，再经气流粉碎机进行粉碎，使回收二氧化硅粉料经激光粒度分布仪测试后的平均粒径≤5um；最后将所制备的回收二氧化硅粉料作为铅酸电池正极铅膏或负极铅膏的添加剂进行使用。使用该方法，巧妙有效地对废旧铅酸蓄电池隔板进行了回收利用，不仅避免了将废旧隔板作为危废进行处理，节约了生产成本，也有利于提升蓄电池循环寿命及活性物质利用率。
