Microvoltammetric studies on single particles of battery active materials

This paper demonstrates the unique features of microvoltammetric techniques to investigate the solid-state electrochemistry of battery materials. It is shown that single particles having 10 gmm sizes were successfully made into the working electrode. Microvoltammograms for LiCoO2 and spinel-related manganese oxides were measured at various sweep rates and their kinetic features were examined.
