PROBLEM TO BE SOLVED: To perform an infrared spectroscopic analysis of a reaction at an electrode of a lithium secondary battery while executing charge and discharge under a charge and discharge condition close to a charge and discharge condition for a real battery of the lithium secondary battery.SOLUTION: An infrared spectroscopic analysis cell comprises a window material, a perforated plate, an electrolytic solution, a porous body electrode, a separator and an electrode. The window member is made of diamond. Infrared light entering an incident part is totally reflected by a reflection part and is emitted from an emission part. An evanescent wave is leaked from the reflection part. The perforated plate is made of a conductive body. The perforated plate holds the window member in a hole so as to arrange the reflection part at an opening. The porous body electrode includes an electrode active material of a lithium second battery. One principal surface of the porous body electrode includes: a reached part that the evanescent wave reaches; and a connected part that is electrically connected to an adjacent part adjacent to the opening. The electrode faces the other principal surface of the porous body electrode across the separator. The porous body electrode, the separator and the electrode are immersed in the electrolytic solution.SELECTED DRAWING: Figure 2 |
