Poly(Ionic Liquid) Binders As Ionic Conductors And Polymer Electrolyte Interfaces For Enhanced Electrochemical Performance Of Water Splitting Electrodes

A poly(ionic liquid) (PIL) was used as a binder for NiCo oxide nanopowder in a water electrolysis standard assay to explore the role of polymers in a model electrocatalytic device. The comparison to technical standard binders such as Nafion or Fumion ionomers showed that the PIL improves the cycling stability under accelerated ageing conditions as well as the activity.
