Solef® PVDF is a copolymer used to coat the separator in Li-Ion batteries with an additional layer in order to extend cycle life etc.
The copolymer is a fluorinated semi-crystalline thermoplastic which is obtained by polymerizing vinylidene fluoride. Without any additives, it has the intrinsic stability inherent to fluoropolymers even when exposed to harsh environments, providing the user with a combination of properties resulting in longer equipment life. In order to extend cycle life with a better interface between electrodes and separator as well as to achieve enhanced wettability and easy assembly, the separator can be coated with an additional layer of Solef® PVDF. This coating can either be solvent based or water based. Solef® PVDF copolymer is normally used in separator coating, because it is easier for copolymer to develop good adhesion to the electrode at a certain lamination condition and it can be dissolved in a wider range of solvents. The solution can be formulated with ceramic or used alone to coat the polyolefin porous substrate.
- •Can be under continuous use within a wide range of temperatures.
- •Can be applied to the automotive industry and its transition to eco-friendly vehicles.
- •Longer shelf-life while shortening charging time.
