Lithium batteries are a challenging application for most polymeric materials, as they demand long-term reliability as well as chemical and electrochemical resistance in the specific chemical environment of Li-ion cells. In the case of automotive applications, higher temperature performance is also required.

PVDF battery separator brings many advantages to the lithium battery industry when used as a binder in the formulation of electrodes as well as in the design of the separator: as a binder, it provides outstanding adhesion and long-term performance; as a separator coating, it enhances the interface between electrode and separator. All these allow our customers to achieve a smoother cell assembly process to produce higher energy density cells with increased cycle life.
