SUMMARY:Chemical Analysis of Lithium in Battery Materials with high spatia
 l resolution using EDS and EELS in the Electron Microscope - Raynald Gauvi
 n\, Professor\, Mining and Materials Engineering\, McGill University

DESCRIPTION:This seminar will present the scanning transmission electron m
 icroscope (STEM) SU-9000 from Hitachi which characterizes thin and massive
  samples with electrons beam energies ranging from 0.1 to 30 keV. This mic
 roscope is equipped with an electron energy loss spectroscopy (EELS) detec
 tor which allows the detection of Lithium. High spatial resolution images 
 are possible with a resolution of 0.16 nm. Many examples will be presented
  on Li materials and on nano-materials. This microscope is equipped with a
  EDS detector of lithium (Extreme\, Oxford Instrument) and the microanalys
 is of lithium compounds\, which is very difficult and challenging\, will a
 lso be covered. The preparation of thin films by focus ion beam (FIB) for 
 high spatial resolution images in STEM will be also shown with the newly a
 cquired Hitachi NX-5000 FIB.
