摘要：

Lithium-iron manganese phosphates (LiFexMn1-xPO4, 0.1 < x < 0.9) have the merits of high safety and high working voltage. However, they also face the challenges of insufficient conductivity and poor cycling stability. Some progress has been achieved to solve these problems. Herein, we firstly summarized the influence of different electrolyte systems on the electrochemical performance of LiFexMn1-xPO4, and then discussed the effect of element doping, lastly studied the influences of conductive layer coating and morphology control on the cycling stability. Finally, the prospects and challenges of developing high-cycling LiFexMn1-xPO4 were proposed.
