In webinar 1/3 of the series Advanced Techniques in Lithium Ion Batteries and Next Generation Battery Material Characterization, we will discuss the solutions for preparing, imaging, and analyzing lithium-ion batteries with various instruments and techniques. We will show examples of the methods used to prepare and transfer the samples to the instrument of choice, in an inert transfer vessel without exposure to the atmosphere.

The first part of the webinar will focus on sample preparation with our air-isolated CROSS SECTION POLISHERTM, imaging with an SEM, and analysis with an Energy Dispersive X-ray Spectrometer (EDS). This will include data from our new Gather-X Windowless EDS detector, which can detect ultra-low energy elements such as lithium (with Li K line of 54 eV). Analyzing lithium and other light elements requires low kV imaging and analysis and often high beam current.

The second part of the webinar will focus on advanced battery analysis data from a field emission Electron Probe Microanalyzer (FEG EPMA) with Wavelength Dispersive Spectrometers (up to 5 WDS + EDS), JEOL’s unique Soft X-ray Emission Spectrometer (SXES), and an Auger microprobe. We will show application examples from all these techniques.

Key learning objectives:

  • Ultra-low energy imaging and microanalysis of batteries
  • Novel light element detection in an SEM or EPMA
  • Specialized techniques in sample preparation and inert transfer of battery-specific materials
