Outline of Final Research Achievements

In this study, new single particle measurement system was established by using the particle/ current collector integrated microelectrode enclosed in a closed three-electrode flange cell. This system enabled consecutive electrochemical measurements on a single electrode particle, in order to evaluate various electrochemical properties such as the electrolyte dependency, the temperature dependency and long-term cyclability. As a result, many findings which lead to the clarification of reaction mechanism of various electrode materials were obtained.
