Preparation method of high-durability kiln furniture for positive electrode material of lithium power battery
The invention discloses a preparation method of high-durability kiln furniture for a positive electrode material of a lithium battery power battery. An inner layer and an outer layer of the kiln furniture are made of different materials respectively; a substrate layer of the outer layer and a corrosion-resistant layer of the inner layer are laminated and molded and then subjected to firing treatment; a laminating integral forming technology is adopted, so that one-time forming of the substrate layer and the corrosion-resistant layer is realized, and strong binding force, high yield and low cost of a green body are ensured; due to the design of the inner layer and the outer layer, the outer layer can be used for obtaining good heat resistance, the inner layer can also be used for obtainingstrong alkali resistance, and on the premise that the mechanical strength is not sacrificed, the kiln furniture weight and the corrosion resistance are both considered.
本发明公开了一种锂电动力电池正极材料用高耐用性窑具的制备方法，窑具的内外层分别采用不同材质；将外层的基底层与内层的抗腐蚀层叠压成型，再进行烧成处理；采用叠压一体成型技术，实现基底层和抗腐蚀层的一次成型，保证坯体结合力强，成品率高，成本低；内外层的设计，既可以利用外层取得良好的耐热性能，又可以利用内层获得强抗碱性，在不牺牲力学强度的前提下，达到窑具重量与耐腐蚀性能的兼顾。
