Overview

The study investigates how polyvinyl alcohol affects porosity in electrodes, suggesting improved electrochemical performance.

Key Points

  • This research aims to explore how polyvinyl alcohol space holders influence the microstructure and porosity of sintered iron electrodes.
  • Porous iron electrodes were created using powder metallurgy with polyvinyl alcohol as a space holder.
  • The powder mixtures were compacted at different pressures (60, 80, 100, 120 MPa).
  • A two-step sintering process was employed: intermediate sintering at 300 °C for PVA removal and final sintering at 1,050 °C under argon.
  • Porosity, pore morphology, and structural connectivity were evaluated through morphological analyses.
  • PVA addition significantly increased open and interconnected pores, enhancing ionic transport.
  • Optimized porosity levels were achieved compared to conventional electrodes, improving electroactive sites.
  • Adjusting compaction pressure allowed control over pore size and electrode stability.
