Advances in Lithium-Ion Battery Development

Thursday, June 23, 2022

Surging demand for lithium (Li)-ion batteries challenges researchers to improve energy storage capacity and efficiency. This webinar highlighted two analytical techniques poised to play vital roles in optimizing Li-ion battery devices and materials.


  • The new scanning electron microscope (SEM) method - composition by difference (Li-CDM) - that allows quantitative analysis of Li ions.
  • Advantages of atom probe tomography (APT) for chemical and structural analysis of Li-ion batteries
  • APT specimen preparation methods and protocols for Li-ion cathode materials
Available on demand.

About the presenters:
David Stowe
David Stowe, DPhil
Product Manager, Cathodoluminescence
Gatan Inc.

David Stowe is a Senior Product Manager responsible for Energy Dispersive X-ray Spectroscopy (EDS) products for EDAX and SEM products for Gatan. He joined Gatan in 2007 as an Application Specialist after graduating with a DPhil and MEng in Metallurgy and Science of Materials from the University of Oxford. In his doctorate and masters research, he used a range of electron beam tools and microscopies to investigate electronic processes in wide band gap materials and to characterize the electrical and optical properties of defects in semiconductors. More recently, he has focused on developing new instrumentation and methodologies to enhance the characterization of materials in the electron microscope.
