摘要：
Voltammetric behavior of spinel lithium manganese oxide on abrasive microelectrode was studied in 1mol/L LiPF6/EC+DMC+EMC(1:1:1), and the morphology and the manganese distribution of the abrasive microelectrode were analyzed by SEM and EDS, respectively. Results show that spinel lithium manganese oxide is more stable on. abrasive microelectrode than on powder microelectrode and has more reversibility for lithium ion extraction/intercalation. Two spinel lithium manganese oxide samples synthesized by solid state process and sol-gel method were compared. The sample synthesized by solid state process shows its better stability for cycling and reversibility for lithium ion extraction/intercalation. This result conforms with the difference in crystallization of two samples, obtained by XRD. Abrasive microelectrode can be used to estimate the cyclic stability of spinel lithium manganese oxide and the reversibility for lithium ion extraction/intercalation fast and effectively.
