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.

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 ?m, and branching of the fibers is observed.
