葡萄糖对微波水热合成正极材料LiFePO4的结构和性能的影响OA北大核心CSCDCSTPCD
Effect of Glucose on Structure and Properties of LiFePO4 Cathode M aterial Prepared by Microwave Hydrothermal Method
以FeSO4·7H2 O ,LiOH · H2 O和 H3 PO4为原料,葡萄糖为改性剂,采用微波水热法合成具有正交晶系橄榄石结构的LiFePO4/C复合材料。借助XRD ,SEM ,EDS和电化学性能测试等分析,研究葡萄糖对产物组成、结构、微观形貌和电化学性能的影响。结果表明:葡萄糖改性后,LiFePO4结构中Fe ,P和O原子间的结合增强,颗粒尺寸减小,表面有碳层包覆,电化学性能提高。LiFePO4/C在0.1 C倍率下的首次放电比容量为12…查看全部>>
Orthorhombic LiFePO4/C composite material with olivine structure was prepared by micro‐wave hydrothermal method using FeSO4 · 7H2 O ,LiOH · H2 O and H3 PO4 as raw materials ,with glu‐cose as carbon source and modifier .T he influence of glucose on the composition ,structure ,morphol‐ogy and electrochemical performance of LiFePO4 was investigated by means of XRD ,SEM ,EDS and constant current charge‐discharge cycling .The results show that the as‐obtained LiF…查看全部>>
