在锂离子电池生产制造中,将液体介质与正负极活性材料、导电剂、粘结剂混合均匀,得到电池浆料,然后涂布在集流体上,利用干燥烘烤等除去溶剂(水或NMP),毫无疑问作为锂电池生产的第一道工序,匀浆配料是重中之重,是一切性能的基础。


In the manufacture of lithium-ion battery production, with liquid medium is the positive and negative active materials, conductive agent, binder are mixed evenly to get the battery slurry, and then coated on the fluid collector, using drying and baking to remove the solvent (NMP) or water, there is no doubt that as the first step of lithium-ion battery production,homogenate ingredients are the most important and the basis of all performance.

而浆料的各项特性参数又是表征或衡量浆料的基础,而浆料电导性又是决定电芯导电性的重要参数,所以找到一种测量浆料电导性及稳定性的方法及仪器非常重要。


And the characteristic parameters of slurry is the basis of characterization or measurement of slurry, and the conductivity of slurry is an important parameter to determine the conductivity of the cell, so it is very important to find a method and instrument to measure the conductivity and stability of slurry.
