Sagger for positive electrode material of lithium ion battery
The invention discloses a sagger for a positive electrode material of a lithium ion battery. The sagger is composed of a low-thermal-expansion material and/or a negative-thermal-expansion material anda lithium ion battery positive electrode material corrosion-resistant material, wherein the low-thermal-expansion material and/or the negative-thermal-expansion material and the lithium ion battery positive electrode material corrosion-resistant material are mixed and molded into a sagger blank, and the sagger blank is sintered to obtain the sagger for the positive electrode material of the lithium ion battery. The sagger disclosed by the invention has the characteristics of thermal shock resistance and lithium ion battery positive electrode material erosion resistance, the service life of the sagger is greatly prolonged, the refractory material consumption of the lithium ion battery positive electrode material is reduced, and the environment is protected. The sagger provided by the invention does not need an additional coating to protect the sagger, so a production process, required equipment and manpower are greatly reduced; and the sagger can be produced only by simple forming equipment and annealing equipment, so production efficiency is improved.
本发明公开一种锂离子电池正极材料用匣钵，由低热膨胀材料和/或负热膨胀材料与耐锂离子电池正极材料侵蚀材料组成，低热膨胀材料和/或负热膨胀材料与耐锂离子电池正极材料侵蚀材料混合后成型为匣钵胚体，经烧成后制得锂离子电池正极材料用匣钵。本发明的匣钵具有耐热冲击性和耐锂离子电池正极材料侵蚀的特性，大大提高了匣钵的使用寿命，减少了锂离子电池正极材料对耐火材料的消耗，保护了环境。本发明的匣钵不需要额外的涂层来保护匣钵，大幅减少了生产流程、所需设备和人工的使用，仅需要简单的成型设备和退火设备就能够进行生产，提高了生产效率。
