Technical FAQs 4

Are PVDF- g-il membranes suitable for redox flow batteries (VRFB)?

Besides, the PVDF- g -IL membranes were systematically evaluated in vanadium redox flow batteries (VRFB). The PVDF- g -IL membrane with a grafting yield of 25% had an ion conductivity of 9.05 mS cm −1 due to the presence of the imidazolium ionic liquid.

What are the properties of PVDF and PVDF/G membranes?

Physicochemical and electrochemical properties of PVDF and PVDF/G membranes. Proton conductivity reflects the migration of a proton through the membranes in an electric field. Using membranes with high conductivity can reduce the internal resistance and improve the efficiency of batteries.

Can nanoporous membranes improve the performance of vanadium flow batteries?

The development of chemically stable and high conductive membranes is one of the most important issues to improve the performance of vanadium flow batteries (VFBs). Herein, poly (vinylidene fluoride) (PVDF)/graphene composite nanoporous membranes were easily fabricated by manipulating crystallization processes.

Are PVDF-Il-PvP membranes a good ion conductor?

The properties of the PVDF-IL-PVP membranes were investigated systematically. The modified membranes showed a great increment in ion conductivity. Additionally, the vanadium permeabilities of PVDF-IL-PVP20 and PVDF-IL-PVP30 membranes were also lower than that of Nafion115.
