電阻的重要性

在鋰離子電池生產(chǎn)制造中，將液體介質(zhì)與正負極活性材料、導電劑、粘結劑混合均勻，得到電池漿料，然后涂布在集流體上，利用干燥烘烤等除去溶劑(水或NMP)，毫無疑問作為鋰電池生產(chǎn)的**道工序，勻漿配料是重中之重，是一切性能的基礎。

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.

而漿料的各項特性參數(shù)又是表征或衡量漿料的基礎，而漿料電導性又是決定電芯導電性的重要參數(shù)，所以找到一種測量漿料電導性及穩(wěn)定性的方法及儀器非常重要。

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.

Measurement of slurry resistance plays the following roles in the process of slurry rapid evaluation and quality monitoring：

1. 綜合評估不同攪拌工藝對膠料電導率（包括分散性、沉降等）影響；
