PVDF(DS202D) Resin For Lithium Battery Electrodes Binder Materials
PVDF powder DS202D is the homopolymer of vinylidene fluoride, which can be used for electrodes binder materials in lithium battery.DS202D is a kind of polyvinylidene fluoride with high molecular weight.It is soluble in polar organic solvent.It is of high viscosity and bonding and easy film-forming.The electrode material which is made by PVDF DS202D has good chemical stability, temperature stability and good processability.As one of the binders, PVDF is widely used in the field of lithium-ion batteries. It connects electrode active material, conductive agent and current collector with each other, the performance and dosage of PVDF binder have a great influence on the electrochemical performance of lithium battery. Generally, high adhesion can improve the cycle life of lithium battery, and the main factors affecting the adhesion are molecular weight and crystallinity.
