With the development of electronic devices and electric vehicles, the demand for rechargeable battery having large capacity is rapidly increasing. Based on the advanced nanotechnology, many researchers have suggested the methods to increase the performance at nano- and micro-scales to meet the demand. However, it is difficult to evaluate the material properties at microscopic and local region using conventional macroscopic analysis methods as well as empirical prediction. In this work, we characterized the electrochemical and mechanical properties of lithium ion at nano- and micro-scale resolution by atomic force microscope. The distribution of lithium ion and diffusion coefficient were calculated, and elastic modulus of deposited lithium was obtained on the next generation lithium battery materials. The importance and impact of the multi-scale characterization to correlate with microscopic and macroscopic analysis will be presented.
