Sagger for graphitization and purification of battery negative electrode and preparation method of sagger
The invention relates to the technical field of sagger production, and discloses a sagger for battery negative electrode graphitization and purification and a preparation method thereof, the sagger comprises the following raw materials by weight: 50-70% of calcined coke, 20-30% of a carburant, 10-20% of graphite scrap, and a binder phenolic resin accounting for 12-18% of the total weight of the raw materials. During preparation, the raw materials are mixed in a mixing mill, a mixing and milling process is adopted to replace an existing wet kneading process, and the mixing process is environment-friendly and dust-free; isostatic pressing is adopted to replace existing heating hydraulic forming, the production efficiency and the qualified rate of semi-finished products are improved, and the formed products are high in strength and can be operated at will without being placed; the sintering period is short, firstly, the sintering period is 3-5 days, the energy consumption is greatly reduced, carbon-buried roasting is not needed, and the method is environment-friendly.
本发明涉及匣钵生产技术领域，公开了一种电池负极石墨化及提纯用匣钵及其制备方法，按重量百分比计，所述匣钵原料组成为50‑70％的煅后焦、20‑30％的增碳剂、10‑20％的石墨碎，外加上述原料总重量12‑18％的结合剂酚醛树脂。本发明制备时原料在混碾机内混合，采用混碾工艺替代现行的湿捏工艺，混合过程环保、无粉尘；采用等静压成型取代现行的加热液压成型，提高了生产效率和半成品合格率，且成型后产品强度高，可随意运转不需放置；烧成周期短，一是烧成周期为3‑5天，能耗大大降低，不需要必须采用埋碳焙烧，环境友好。
