In the Synthesis and Characterization of Inorganic Materials (LSCIM) by Dr. Xiaoling Xiao, LiCoO2 nanoplates with the exposure of (001) plane are successfully synthesized to deliver high rate capability. Though the (001) plane of LiCoO2 is not electrochemically active, the charge/discharge capacity of as-prepared LiCoO2 nanoplates can still keep 113 mAh/g at 7 C after 100 cycles. The good rate capability is beneficial from those cracks on the LiCoO2 nanoplates which are perpendicular to (001) plane and are favorable to the fast Li+ transportation. In addition, those cracks are helpful to the access of the electrolyte to the internal surface throughout the electrode.
