Product Description of PVDF Powder Lithium Battery FR905

PVDF resins are polymers currently widely used by Li-ion battery manufacturers as binder material, especially in cathodes. PVDF requires NMP (N Methyl 2-pyrrolidone) as a solvent and offers the possibility of high voltage operation. PVDF is also electrochemically stable in contact with electrolyte mixtures. Targray has established a leading supply partner to offer Li-ion battery manufacturers a portfolio of PVDF options.

Polyvinylidene Fluoride (PVDF) resin is the homopolymer of Vinylidene Fluoride. Targray offers a range of PVDF materials with differing properties that allow you to maximize the performance of your particular cell. PVDF powder is a raw material, however, the following are benefits of the PVDF binder:

Excellent resistance to adverse weather conditions over a wide range of temperatures

Excellent mechanical strength

Outstanding chemical resistance

Good processing performance and workability

Note:

PVDF resins have good thermostability at the temperature below 310℃. However, it will decompose into the toxic
hydrogen fluoride and fluorocarbon if it is idle for a long time at the temperature between 310~ 320℃. It is not suggested
to use PVDF resin at temperature higher than370℃ because this will accelerate the decomposition velocity in such
an environment. Besides, please keep in mind that PVDF resin will release toxic hydrogen fluoride and fluorocarbon when it burns
