Various polyvinylidene difluorides (PVDF) as polymeric binding agent in lithium‐ion battery were rheologically evaluated on high capacity and excess lithium‐LiNi 0.6 Mn 0.2 Co 0.2 O 2 (Ni‐rich NMC). We found that the suspension polymerized PVDF binder is more stable upon gelation for long duration while other high molecular weight PVDF binders (MW > 900,000) show irreversible rheological transformation that can dramatically compromise the coating step during lithium‐ion battery electrode slurry preparation.
