Sulfonated Polystyrene/Polybenzimidazole Bilayer Membranes for Vanadium Redox Flow Batteries

open access: yesAdvanced Energy Materials, EarlyView.
PBI‐coated sulfonated polystyrene membranes are prepared, and the performance of the various possible assemblies of two such membranes is tested. A 52 µm thick PSSP assembly can be fabricated with a materials cost of just 1.84 USD m−2, and shows an energy efficiency of 89.7% at 80 mA cm−2.

Tuning the Performance of Poly(quaterphenyl piperidinium) Anion‐Exchange Membranes by Monomer Configuration

open access: yesAdvanced Energy Materials, EarlyView.
Ether‐free poly(quaterphenyl piperidinium) ionomers are prepared by superacid‐mediated polyhydroxyalkylations and explored as hydroxide conducting membranes. The para‐meta configuration of the quaterphenyl monomer greatly influences polymer backbone flexibility.
