Ammonia-free synthesis of lithium manganese iron phosphate cathodes <i>via</i> a co-precipitation reaction

Abstract

A novel precursor phase (Mn, Fe) 5 (PO 4 ) 2 (HPO 4 ) 2 ·4H 2 O is introduced with a co-precipitation reaction, enabling a low-cost, sustainable, scalable production of LMFP cathodes exhibiting excellent cycling stability with good tap density.
