SAGGAR FOR SINTERING LITHIUM TRANSITION METAL OXIDE, AND PREPARATION METHOD THEREFOR
Disclosed are a sagger for sintering lithium composite transition metal oxide and a preparation method thereof. The sagger includes a substrate layer and a shallow layer on a surface of the substrate layer, and a coating layer. The substrate layer is prepared from the following raw materials: silicon carbide, magnesia-alumina spinel, aluminum oxide-magnesium oxide-yttrium oxide composite fiber, zircon powder and a binding agent; the shallow layer is prepared from the following raw materials: silicon carbide, magnesia-alumina spinel, aluminum oxide-titanium oxide composite fiber, yttrium oxide-zirconium oxide composite fiber and a binding agent; and the coating layer is prepared from the following raw materials: silicon carbide, magnesia-alumina spinel, magnesium oxide, zirconium oxide fiber, lithium composite transition metal oxide powder and a binding agent. The sagger of the present disclosure has properties of good corrosion resistance and a small coefficient of thermal expansion. When cathode materials contact the sagger, corrosive phenomena, such as cracking, peeling, falling chip, and the like, are not easy to occur on the sagger, thereby improving the service life of the sagger.
