| Outline of Final Research Achievements |
In the present study, we established a method to obtain the lithium distribution of lithium-ion battery cathode (LiCoO2 as an active material) and anode (graphite) using laser-induced breakdown spectroscopy (LIBS) measurements. Linearity of the calibration curve of lithium was improved by performing LIBS measurement in a reduced argon atmosphere of 1000 Pa. We could quantitatively or semi- quantitatively display lithium distribution of the cathode and anode after charge-discharge tests by measuring them in the reduced argon atmosphere.
