Electrochemical Properties of LiMnPO4 Cathode Material Prepared by Ball-Milling

Abstract:

The ball-milling LiMnPO4 powders for lithium-ion batteries were synthesized by high temperature solid-phase method. The effects of ball-milling on the microstructure and electrochemical performance of LiMnPO4 cathode material were investigated. The XRD patterns showed that the LiMnPO4 sample with ball milling 20h had single ordered olivine structure. The SEM images revealed that spherical particles distributed uniformly. The LiMnPO4 powders, of which the initial charge and discharge capacities at 0.05C rate were 133.9 and 66.4mAh•g-1 at 0.05C rate were prepared at 700°C for 20h with ball milling 20h.
