Abstract

To understand the role of structure on the position of the octahedral Fe 3 + / Fe 2 + redox couple in compounds having the same polyanions, four iron phosphates: Li 3 Fe 2 ( PO 4 ) 3 , LiFeP 2 O 7 , Fe 4 ( P 2 O 7 ) 3 , and LiFePO 4 were investigated. They vary in structure as well as in the manner ...
