PVDF by Emulsion: the go-to Enabler for Solvent-free Technology in Battery Cell Manufacturing

电池电极和隔膜涂覆

在本白皮书中，我们深入探讨电池电极和隔膜涂覆的生产制造，了解乳液法PVDF用于电池制造的应用案例。聚偏氟乙烯(PVDF)是锂离子或钠离子电池制造行业公认的粘接剂，满足正极粘接剂或隔膜涂层所需要的最关键的材料性能。

锂离子电池技术所需的材料重要特性：

1. 优异的电化学性能; 纯度高
2. 机械性能稳定
3. 加工性能好

Case 1: Water-based Technologies - Separator Coating

In the first case, we explain how applying the conventional solvent-based technology to the water-based system does not give the desirable results in terms of adhesion and particle size. We demonstrate how the emulsion process results in precise and optimized PVDF coatings for battery cell separator coating. 

Case 2: Dry Process - Electrode Manufacturing

In the second case, we decode the dry process electrode manufacturing and how our PVDF can achieve the optimum in the deagglomeration process of the secondary particles.
