锂电池（LiBs）电芯的主要成分
研磨
有一种正负极材料合成叫做固态工艺。
在该工艺路线中，活性材料是由原材料在适当的工艺炉中通过化学转化生产的。根据所用原料的不同，合成前可能需要对原料进行湿法研磨和干法预磨。
因此，材料越细，混合就越均匀，因此，为了提高电池的效率，材料的解团聚过程非常重要。
研磨
来自外部的冲击应力能量使颗粒产生形变断裂面，如果这个能量超过临界值，则颗粒被破碎。外部能量进入产品内部，形成新的颗粒表面。
解团聚
原始颗粒非常细（微米以下）。然而，它因为静电或干燥过程团聚在一起。解团聚是干法分散工艺，不会形成新的表面积。
工艺解决方案
System Solution
Pumping solutions like NEMO® progressing cavity pumps or PERIPRO peristaltic pumps are the important machines in battery producing lines, that have been used to convey many kinds of glue and battery slurry and so on mediums, as the dosing and metering pumps, mainly application in the battery slurry process and coating procedure.
The axial speed is very small that means low shear rate is applied into the medium, so the results is that the mechanical and chemical characteristics of the medium does not change conserves its viscosity without break any emulsion. When pumping solution is used, pump keep the same volumetric displacement each rotation, the flux volume can be based on the volumetric displacement.
With pumping solution, it is possible to keep linear performance with the rotating speed, the same volumetric displacement each rotation. And, there is no pulsation, continuous uninterrupted flow. For shear sensitive Mediums, low shear factor of all type of pumps, can handly solids particles without damage them, with High solid, high viscosity.
Especially, when producing lithium-ion battery electrode, usually select pumps to dose or meter kinds of slurry for positive pole or negative pole, including solvent series liquid and water series medium.
Analyzing Solution
In the process of making the batteries anode and cathode, the raw material is heat-treated and sintered.
烧结是将混合原材料加热并使其成为热固性材料的过程。要进行热处理和烧结，就必须了解电池原材料和活性材料的热特性。
通过对活性材料进行热分析，可以根据每种活性材料的成分确定其热行为。 例如，当活性材料与O2和H2 等活性气体发生反应时，活性材料的性质就会发生变化。 为了避免这种现象，有一种方法是用TGA和DSC 测量热性质。TGA 分析手套箱中N2和 Ar 等惰性气体环境下的质量变化。此外，热分析产生的气体还可以通过将GC-MS 或QMS与 TGA 或STA 联用来进行分析。此外，还可利用DIL 或TMA 评估材料的烧结情况。
