TRANSMISSION ELECTRON-MICROSCOPY OF CARBONS FOR LITHIUM INTERCALATION

Transmission electron microscopy (TEM) is a powerful tool which we are applying to study the microstructure of carbonaceous materials that a re used as lithium-intercalation electrodes in lithium-ion cells. The results of our study on the relationship between the physicochemical p roperties of carbon, with strong emphasis on the microstructure observ ed by TEM, and their capability for electrochemical intercalation of l ithium will be summarized. In addition, progress on the fabrication of a microcell for in situ TEM of lithium-intercalation in carbon will b e discussed.
