General description

Iron(II) sulfate hydrate is a highly water soluble, blue green crystalline solid at room temperature. It is paramagnetic in nature and widely used in the field of redox batteries, nanomaterial synthesis and water treatment.

Application

Iron(II) sulfate hydrate can be use:
  • As precursor to prepare polyanionic electrodes for secondary Li-ion batteries. It serves as an iron source to produce low cost and sustainable battery materials.
  • As an electrolyte precursor to fabricate cost effective and scalable redox flow batteries with excellent capacity retention.
  • As a starting material to prepare superparamagnetic iron oxide nanoparticles.
  • As a support material to fabricate air pollutant sensors.
