摘 要:采用何种方法对锂电池浆料进行微细分散直接影响锂电池均一性品质及其分散效率。目前,常用行星混合设备这种宏观尺度的随机性混合分散形式对锂电池浆料进行混合分散,存在着混合不彻底和效率低的问题。为提高锂电池浆料分散品质与效率,文章对锂电池浆料的特性及超剪切分散机理进行研究,采用高精密超剪切分散设备对锂电池负极浆料进行了分散实验。实验结果表明,超剪切分散不仅提高了锂电池浆料的混合分散品质、显著提高了混合效率,而且可以减少电极浆料中液体介质用量,缩短浆料烘烤时间,提高涂布效率。The micro-dispersion method of lithium ion battery slurry directly affects the uniform quality and dispersing efficiency.Currently,the planet mixing equipment with random macro-scale dispersion process is used for the dispersion of lithium ion battery slurry,not only incomplete mixing,but also low efficiency.In order to increase dispersing quality and effficiency of lithium battery slurry,the paper studied the characteristic of lithium battery slurry and the ultra-shear dispersion mechanism.Some experiments for dispersing the cathode lithium ion slurry have been done by the high precise-shearing disperser.The results show that utilization of the high-shear technology in the lithium ion battery slurry is beneficial to not only improve its uniform quality and mixing efficiency remarkably,but also reduce the dosage of medium,shorten the baking time and raising the coating efficiency.
