Abstract

A reproduction and short discussion on the phase and evolution of Li₃Fe₂(HPO₃)₃Cl presented in the article entitled Li₃Fe₂(HPO₃)₃Cl: an electroactive iron phosphite as a new polyanionic cathode material for Li-ion battery (Hooman Yaghoobnejad Asl, et al., J. Mater. Chem. A, 2015, 3, 7488) are given. According to our reproduction, the major phase in the temperature range by Hooman Yaghoobnejad Asl, et al. is not Li₃Fe₂(HPO₃)₃Cl, but is Fe₁₁(HPO₃)₈(OH)₆ and the major impurity phase is not Li_1.43[Fe_4.43^IIFe_0.57^III(HPO₃)₆]·1.5H₂O as claimed by the authors. More detailed experimental parameters are suggested to be given.
