Lithium-Ion Battery Based on LiMn0.5Fe0.5PO4 Cathode and Lithium Alloying Anode
Herein we report the synthesis and characterization of LiMnPO4, LiFePO4 and mixed LiMn0.5Fe0.5PO4 materials through solvothermal approach. Careful analysis of the electrochemical properties by potentiodynamic cycling with galvanostatic acceleration and galvanostatic cycling techniques were carried out in order to investigate the features of the Fe3+/Fe2+ and Mn3+/Mn2+ redox couples in the olivine structure. In addition, an advanced lithium-ion battery formed by combining a LiMn0.5Fe0.5PO4 cathode with a Sn-C anode is reported. The figure shows the galvanostatic cycling results of a Sn-C/LiMn0.5Fe0.5PO4 cell.
