Synthesis and characterization of carbon-coated LiMnPO4 and LiMn1−xFexPO4 (x = 0.2, 0.3) materials for lithium-ion batteries

► C-LiMn1−xFexPO4 (x = 0, 0.2, 0.3) were synthesized via a cost-effective procedure. ► LiMnPO4 from totally soluble precursors provided an attractive C-coated material. ► The best performing electrodes are based on LiMnPO4 and LiMn0.8Fe0.2PO4.
