Many of our electronic devices are powered by rechargeable lithium-ion batteries. Use of these batteries could soon extend into many other areas, including transport through the ongoing development and adoption of electric vehicles. Scientists involved in developing and improving batteries require precise, sensitive techniques for analyzing and characterizing these materials and technologies.
This EKB introduces the main analytical techniques used to characterize lithium-ion battery materials. In particular, it focuses on nanoindentation, a very common method for measuring the mechanical properties of materials, and atomic force microscopy characterization, which works by ‘touching’ the surface of materials with a mechanical probe to map their topography and properties with nanoscale resolution.
