摘要
The present invention relates to a method for analyzing lithium ion mobility inside a lithium secondary battery comprising: an electrode assembly including a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode; a battery case equipped with the electrode assembly; and a nonaqueous electrolyte for impregnating the electrode assembly. The present invention relates to the method for analyzing lithium ion mobility inside the lithium secondary battery through a synchrotron X-ray image capable of analyzing the lithium ion mobility inside the lithium secondary battery through difference in shadow intensity between a first image projected when a synchrotron X-ray passes through the lithium secondary battery after charging/discharging of the lithium secondary battery and a second image projected when the synchrotron X-ray passes through the lithium secondary battery before charging/discharging of the lithium secondary battery.
