Surface Analysis of Modern High-Capacity Battery Materials Webinar

Presented by Benjamin Schmidt, Ph.D., Senior Staff Scientist

Lithium-ion and alternative battery technologies with higher capacities, faster charge times, and fewer safety hazards are in great demand from the automotive to the handheld electronics industries.  These battery systems include complex multi-layered materials with specific roles where surface interactions play a large part in the overall device performance.  For solid-state batteries, fundamental questions are under investigation regarding solid-electrolyte interphase (SEI) development and dendrite evolution, for example.  The ability to chemically characterize these features with high depth resolution is critical for optimizing the battery.

In this 45 minute webinar, the capabilities of PHI instruments for analysis of battery materials will be discussed.  Our dedicated X-ray photoelectron spectroscopy (XPS), time-of-flight secondary ion mass spectrometry (ToF-SIMS), and Auger electron spectroscopy (AES) instruments each provide complementary imaging and spectroscopy information about chemical species, chemical compositions, and chemical states.  Combined with optional accessories, these properties and others can be evaluated as a function of in situ temperature and voltage cycling, both at the surface (up to ~10 nanometers) and at depth (up to ~1 micrometer).  With probe diameters ranging from a few nanometers to a few micrometers, measurements can be collected with high spatial resolution or averaged over larger practical areas.  Lastly, sample handling options are available to connect instruments directly to glove boxes or use controlled-environment transfer vessels to minimize environmental exposure between instruments.  Overall, Physical Electronics provides an excellent suite of analytical capabilities to research all components of batteries at all stages of production.
