Synthesis and Electrochemical Performance of LiMnPO4 by Hydrothermal Method

Synthesis and Electrochemical Performance of LiMnPO4 by Hydrothermal Method

LiMnPO4 with olivinestructure which is the promising candidate for high voltage cathode material was synthesized by hydrothermal method. In order to synthesize high purity and well-defined LiMnPO4, several precursors for Li, Mn, and P sources and hydrothermal reaction parameters including temperatur...
