Sagger for sintering medium-low nickel ternary positive electrode material and preparation method of sagger
The invention discloses a sagger for sintering a medium-low nickel ternary positive electrode material and a preparation method of the sagger. The preparation method comprises the following specific steps: S1, adding a mixed solution into a mixture, and stirring to obtain a green body material; s2, the green body material is subjected to pouring vibration molding, curing, demolding and re-drying, and a green sagger is obtained; s3, performing heat treatment on the green body sagger, and cooling to room temperature to obtain the sagger for sintering the medium-low nickel ternary positive electrode material; wherein the mixture comprises magnesium aluminate spinel particles, aluminum nickel spinel fine powder, petalite fine powder, magnesium aluminate spinel fine powder and calcium dialuminate fine powder; the mixed solution is obtained by mixing potassium fluozirconate, aluminum fluoride and water. The method is simple in process and low in sintering temperature, and the prepared sagger for sintering the medium-low nickel ternary positive electrode material is good in sintering performance, high in strength, high in thermal shock stability and high in erosion permeability resistance.
本发明公开了一种中低镍三元正极材料烧结用匣钵及其制备方法。制备方法具体步骤如下：S1、向混合料中加入混合液搅拌得生坯料；S2、将生坯料浇注振动成型、养护、脱模和再干燥得到生坯匣钵；S3、将生坯匣钵热处理后冷却至室温得中低镍三元正极材料烧结用匣钵；其中，混合料包括镁铝尖晶石颗粒、铝镍尖晶石细粉、透锂长石细粉、镁铝尖晶石细粉和二铝酸钙细粉；混合液由氟锆酸钾、氟化铝和水混合得到。本发明方法工艺简单，烧结温度低，所制备的中低镍三元正极材料烧结用匣钵烧结性能好，强度大，热震稳定性高，抗侵蚀渗透性强。
