Enhanced electrochemical performance of different morphological C/LiMnPO4 nanoparticles from hollow-sphere Li3PO4 precursor via a delicate polyol-assisted hydrothermal method

With the hollow-sphere Li 3 PO 4 as precursor, a delicate polyol-assisted hydrothermal method is devised to synthesize high-performance LiMnPO 4 . Orthorhombic shaped, irregular flaky shaped and sphere-like LiMnPO 4 are sequentially prepared by decreasing the water–diethylene glycol (DEG) ratio. The capacity, cycling stability and rate performance of all samples prepared by the new synthesis method are improved significantly. And the C/LiMnPO 4 with irregular flaky shape exhibits a capacity of 154.1 mA h g −1 at C/20, 147.4 mA h g −1 at C/10 and 102.5 mA h g −1 at 2 C, which is the best performance ever reported for LiMnPO 4 active material with similar carbon additives.
