Natural cubic‐FeS 2 is embedded in a stabilized polyacrylonitrile (PAN) matrix . The PAN matrix confines the electroactive reduced species of FeS 2 and captures intermediate polysulfide and elemental iron to prevent their dissolution into the electrolyte. The formation of orthorhombic‐FeS 2 is observed at full charge, which is consistent with previous studies.
