A novel nanoporous Fe-doped lithium manganese phosphate material with superior long-term cycling stability for lithium-ion batteries

Abstract

Here, we prepared LiMn_0.8Fe_0.2PO₄ microspheres with an open three-dimensional nanoporous structure by a facile ion-exchange solvothermal method. The micro/nano-structured material exhibits an ultralong cycle life, and retains a reversible capacity of 105 mA h g⁻¹ after 1000 cycles at 5 C, corresponding to the capacity retention of 94.0% and only 0.0068 mA h g⁻¹ loss per cycle.
