Abstract

采用流变相辅助微波合成法,制备了结晶度好、纯度高的尖晶石相的锂离子电池正极材料LiAl0.03Mn1.97O4。对其进行了XRD分析和SEM研究,并与传统固相法制备的LiMn2O4和LiAl0.03Mn1.97O4进行了比较。结果表明,该合成法制备的LiAl0.03Mn1.97O4具有优良的电化学性能,用这种材料制造的电池具有比较高的首次放电容量(115 mAh/g)以及良好的可逆性和循环性能,25次循环后比容量几乎不变,保持在115 mAh/g左右。

Other Abstract

The LiAl_(0.03)Mn_(1.97)O_4 used in lithium-ion batteries was synthesized by a rheological-phase-assisted microwave synthesis method.The samples were compared with LiMn_2O_4 and LiAl_(0.03)Mn_(1.97)O_4 obtained from the traditional solid-state reaction method and were investigated by XRD and SEM.The sample was used as cathode material for lithium-ion battery,whose charge/discharge properties and cycle performance were examined.The results reveal that the powder prepared by this method exhibits a higher initial discharge capacity of 115 mAh/g,much better reversibility and good cycling stability,after 25 cycles without discharge capacity fading,retaining 115 mAh/g.
