Query: Synthesis and Characterization of a LiFe0.6Mn0.4PO4 Olivine Cathode for
  Application in a New Lithium Polymer Battery   A LiFe0.6Mn0.4PO4 (LFMP) cathode exploiting the olivine structure is herein
synthesized and characterized in terms of structure, morphology, and
electrochemical features in a lithium cell. The material shows reversibility of
the electrochemical process which evolves at 3.5 and 4 V versus Li+/Li due to
the Fe+2/Fe+3 and Mn+2/Mn+3 redox couples, respectively, as determined by
cyclic voltammetry. The LFMP has a well-defined olivine structure revealed by
X-ray diffraction, a morphology consisting of submicron particle aggregated
into micrometric clusters as indicated by scanning and transmission electron
microscopy, with a carbon weight ratio of about 4% as suggested by
thermogravimetry. The electrode is used in lithium cells subjected to
galvanostatic cycling with a conventional liquid electrolyte, and demonstrates
a maximum capacity of 130 mAh g-1, satisfactory rate capability, excellent
efficiency, and a stable trend. Therefore, the material is studied in a lithium
metal polymer cell exploiting an electrolyte based on polyethylene glycol
dimethyl ether with a solid configuration. The cell reveals very promising
features in terms of capacity, efficiency, and retention, and suggests the LFMP
material as a suitable electrode for polymer batteries characterized by
increased energy density and remarkable safety.
