What is PVDF powder used for? Polyvinylidene fluoride more commonly known as (PVDF) polymers, are widely used as binders in lithium ion batteries. It can be injected, molded or welded and is commonly used in the chemical, semiconductor, medical and defense industries, as well as in lithium-ion batteries. Such delaminating process of the active mass leads to declining the performance of lithium-ion batteries during the process of charging-discharging, quick capacity fading and decreasing the battery serviceability. For this reason it is very important to select a binder, which will reduce the delaminating the active mass. PVDF plays an important role in powering batteries, particularly, the lithium-ion batteries. This is due to its high level thermal and electrochemical stability as well as its excellent adhesion between electrode films and collectors.
