Microporous graphite crucible for negative electrode material, and manufacturing method thereof
The invention discloses a microporous graphite crucible for a negative electrode material ,and a manufacturing method thereof. The microporous graphite crucible comprises the following components: petroleum coke particles, a pore forming agent and a binder. The method comprises the following steps: crushing petroleum coke, screening petroleum coke particles, carrying out dry mixing on the petroleum coke particles and a pore-forming agent, adding a binder, carrying out wet mixing, putting a wet material obtained after wet mixing into a mold, molding, roasting, graphitizing to obtain a crude product, and finally machining to obtain the finished product of the microporous graphite crucible. The obtained microporous graphite crucible can discharge volatile components in a negative electrode material in time in the graphitization process of the negative electrode material, so that crucible explosion and furnace spraying accidents are prevented.
本发明公开了一种用于负极材料的微孔石墨坩埚及其制作方法，其成分包括以下组分：石油焦颗粒、造孔剂和粘结剂。石油焦经过粉碎、筛选出石油焦颗粒，石油焦颗粒与造孔剂进行干混，然后加入粘结剂进行湿混，将湿混后的湿料放入模具中成型，经过焙烧，石墨化得到粗品，最后经过机加工得到微孔石墨坩埚成品，所得微孔石墨坩埚可以在负极材料石墨化过程中，将负极材料中的挥发性成分及时排出，防止坩埚炸裂和喷炉事故的发生。
