Abstract:

LiMnPO₄ cathode material for lithium ion batteries was synthesized by high temperature solid-phase method using MnCO₃, Li₂CO₃, NH₄H₂PO₄ as raw materials. The structure of samples was identified by XRD analysis and the particle surface morphology was examined by SEM. The results of XRD showed that the LiMnPO₄ sample sintered at 700°C for 20h had single ordered olivine structure. The SEM pattern showed that spherical particles distributed uniformly. Respectively, it figured out that the initial charge and discharge capacities of the samples at 0.05C rate were 133.9 and 66.4mAh•g^-1.
