A Stabilized PAN-FeS2 Cathode with an EC/DEC Liquid Electrolyte

A Stabilized PAN-FeS2 Cathode with an EC/DEC Liquid Electrolyte

Natural cubic‐FeS2 is embedded in a stabilized polyacrylonitrile (PAN) matrix. The PAN matrix confines the electroactive reduced species of FeS2 and captures intermediate polysulfide and elemental iron to prevent their dissolution into the electrolyte. The formation of orthorhombic‐FeS2 is observed...

Zusammenfassung:Natural cubic‐FeS2 is embedded in a stabilized polyacrylonitrile (PAN) matrix. The PAN matrix confines the electroactive reduced species of FeS2 and captures intermediate polysulfide and elemental iron to prevent their dissolution into the electrolyte. The formation of orthorhombic‐FeS2 is observed at full charge, which is consistent with previous studies.
