Abstract
A method for evaluating a dry electrode mixture includes applying vibration to the dry electrode mixture for a predetermined time, and determining a dispersibility of the dry electrode mixture based on an analysis of the dry electrode mixture to which the vibration has been applied. For example, the analysis includes analyzing at least one of a color of the dry electrode mixture, a scanning electrode microscope image of the dry electrode mixture, an electrical conductivity of the dry electrode mixture, a content of the dry electrode mixture, or a combination thereof.
