| 摘 要： | 运用电化学阻抗谱（EIS）研究尖晶石LiMn2O4电极在1mol／L的LiNO3水溶液中的贮存和首次脱锂过程。实验结果表明：尖晶石LiMn2O4电极在上述水溶液电解液中，无论是在贮存还是在充放电过程中，均会受到不同程度的腐蚀，致使锂离子在尖晶石LiMn2O4中的嵌脱过程变得困难。

| Abstract: | The storage behavior and the process of first delithiation of spinel LiMn2O4 in 1 mol/L LiNO3 aqueous electrolyte had been investigated by electrochemical impedance spectroscopy (EIS). It was found that, the process of insertion and deinsertion of lithium ion became difficult during both the storage and the process of first delithiation of spinel LiMn2O4, due to the corrosion of spinel LiMn2O4 in 1 mol/L LiNO3 aqueous electrolyte. |
