Abstract

In this communication, we use first-principles based multi-level computational methods to predict the crystal structure of Li_4C_6O_6, the key intermediate material that can be oxidized to Li_2C_6O_6 or reduced to Li_6C_6O_6. This predicted structure leads to an X-ray diffraction (XRD) pattern in good agreement with experiment, validating the predicted structure. With this structure in hand one can proceed to determine details for the electrochemical properties of these organic electrodes (chemical potential for Li ion as a function of loading and the mechanism for the lithiation/delithiation process) useful in designing optimum systems.
