Research Abstract

We have developed a new in-situ nanoscale diffusion measurement method in solids for secondary lithium-ion batteries using a radioactive 8Li tracer. We have found the detection limit of the lithium diffusion coefficient can be improved to the order of 10^<-12>cm^2/s by detecting α particles emitted at a small angle relative to a sample surface that is irradiated with a low-energy 8Li of about 8 keV.
