Abstract

A LiMnPO₄–LiMn₂O₄ (LMP–LMO) nanocomposite cathode is synthesized by a one-step polyol-assisted pyro-synthesis followed by mild annealing for rechargeable lithium-ion batteries. The LMP–LMO cathode delivered an initial discharge capacity of 142 mA h g⁻¹ and also maintains about 90% capacity retention for over 50 electrochemical cycles.
