Forming method of sagger for lithium battery positive electrode material
The invention discloses a forming method of a sagger for a lithium battery positive electrode material, which comprises the following steps: A, adding raw materials into a stirrer for stirring to obtain sagger processing raw materials; b, performing low-temperature drying on the sagger processing raw materials, and adding the sagger processing raw materials into a mold for pre-pressing molding; c, the blank obtained after prepressing forming is air-dried and then taken out; d, the taken-out blank is added into a forming mold and covered with a sealing cover, and then the interior of the forming mold is vacuumized and subjected to pressure forming; and E, the saggar obtained after pressure forming is subjected to low-temperature drying again, and the saggar for the lithium battery positive electrode material is obtained.The forming method is easy to operate, the saggar blank high in density and good in pressure resistance can be improved, and the subsequent saggar machining quality is further improved.
本发明公开了一种锂电池正极材料用匣钵的成型方法，包括以下步骤：A、将原材料加入搅拌机中搅拌，得到匣钵加工原料；B、将匣钵加工原料进行低温干燥，并加入模具中进行预压成型；C、将预压成型后的坯料进行风干后取出；D、将取出的坯料加入成型模具中，并盖上密封盖，之后对成型模具内部进行抽真空并加压成型；E、之后对加压成型后的匣钵再次进行低温干燥，即得到锂电池正极材料用匣钵，本发明采用的成型方法操作简单，能够提高密度高、抗压性好的匣钵坯料，进一步提高后续匣钵加工质量。
