Application

Manganese(II) nitrate hydrate can be used:
  • To fabricate tetragonal LiMn2O4 as a dual-functional pseudocapacitor-battery electrode via an in-situ ion-exchange method.
  • As a safe, cost-effective, and efficient electrolyte for rapid energy storage applications like supercapacitors.
  • As a precursor to prepare hybrid catalyst to enhance contaminants poisoning tolerance in solid oxide fuel cell cathodes.
  • To prepare MnO2–CoO catalyst to fabricate opto-electronic humidity sensors.
