We have developed an in situ and nanoscale Li diffusion measurement method in Li battery materials using an 
-emitting radioactive Li tracer. In this method, while implanting a low-energy (8 keV) Li beam, the particles emitted at a small angle (10
) relative to the sample surface were detected as a function of time. Measurement for Li diffusion coefficients in a spinel phase LiMn
O (LMO) thin film has been started, which is used as an electrode in a Li ion secondary battery. An obvious Li diffusion effect in LMO was observed at the sample temperature of 623 K, and the further measurement is underway.
