Obtaining a Fibrous Polymeric Material from a Mixture of Polyvinylidene Fluoride and Polystyrene by Capillary-free Electrospinning for a Sealed Lead-Acid Accumulator Separator

The paper considers the most significant properties of moulding solutions based on a mixture of polyvinylidene fluoride and polystyrene for the process of capillary-free electrospinning nonwoven materials. It has been shown that the material obtained from the mixed solution of polyvinylidene fluoride and polystyrene in the ratio of components 0.75 : 0.25 is the largest porous, the diameter of the fibers is in the widest range from 0.14 to 2.8 μm, and branching of the fibers is observed.

Efficiency of Oxygen Ionization in the Mock-up of Lead-Acid Battery with Use Separator from Absorptive Glass Mat and Non-Woven Fibrous Materials Based on Polyvinylidenfluoride and Polystyrene

The efficiency of oxygen ionization in a lead-acid mock-up was studied using a separator based on an absorptive glass mat (AGM) and polymer non-woven fibrous materials based on F-2M polyvinylidene fluoride and polystyrene. Fibrous material obtained by capillary-free electrospinning. The technological and structural characteristics of the polymer material are investigated. It was found that the use of a sandwich polymer/AGM/polymer separator significantly increases the efficiency of oxygen ionization.
