Abstract

This disclosure provides a method of tagging binders in electrodes to allow for easy visualization. In particular, environmentally friendly organic molecules are used as organic fluorescent tags. The organic fluorescent tag will react with alkene moieties within the binder through cycloadditions to introduce a fluorescent tag, which is easily visualized to allow visualisation of binder distribution within the electrode.
