The ion beam driven nuclear analysis has been developed for many years by using various electrostatic accelerators. A proton micro-beam with the beam diameter of ∼1.5 μm at Takasaki Ion Acceleration for Advanced Radiation Application (TIARA), JAEA was used to analyze the positive electrode of the Li-ion battery with PIGE and PIXE. WThe PIGE and PIXE images of Li and Ni respectively for LixNi0.8Co0.15Al0.05O2(x = 0.75 ∼ 1.0) anodes have been taken. The PIGE images of LixNi0.8Co0.15Al0.05O2 particles and the depth profile of the Li density have been obtained with high spatial resolution (a few μm). The images of the Li density distribution are very useful for the R&D of the Li ion battery. In order to make the in-situ ion beam analysis of the Li battery possible, a compact accelerator for a high quality MeV proton beam is necessary. Form this point of view, the diagnostics of Li ion battery is an appropriate field for the applications of laser produced ion beams.
