Abstract
In situ neutron diffraction analysis was employed to study the behavior of the cathode and anode materials in a commercial Li-ion cell (Saehan Enertech, Inc) using the exact configuration of the commercial product. Accurate lattice parameters were refined for the type cathode based on measurements collected as a function of the state of charge. Simultaneous structural characterization was possible on the graphitic anode as well. The simultaneous direct correlation of structural information for both the anode and cathode with the electrochemical data provided a highly detailed picture of the behavior of the active cell materials that ultimately underlie the cell performance. © 2003 The Electrochemical Society.
