【摘要】 研究了Li/CDMO电池的放电反应机理.XRD、XPS等实验结果表明,电池反应是锂在正极内的电化学嵌入反应.用恒电流间隙滴定法（GITT）测得锂在正极中的扩散速率为10^-9cm²·s^-1量级,与锂在层状化合物中的扩散速率相当,结合Li/CDMO电池的热力学行为,Li/CDMO电池的放电反应历程是锂首先客居于层状结构的Li₂MnO₃中,然后再通过热弛豫进入γ-β-MnO₂的晶格.更多还原

【Abstract】 The reaction of cell Li / CDMO has been studied with XRD, XPS and electrochemical method from XRD and coulombic titration, we gained that the thermodynamics of the cell was determined by γ-β-MnO2. The chemical diffusion coefficient of lithium in CDMO was determined by GITT method to be about 10-9cm2 · s-1. These phenomena suggested that the discharge reaction is the intercalation reaction of lithium into host structure.更多还原
