Abstract

The doping mechanism of poly (1-pyrenemethyl methacrylate) (PPy) is investigated through electrochemical analytical and spectroscopic method. The performance of PPy as a Si materials binder is studied and compared with that of a commercial available lithium polyacrylate (PAALi) binder. The pyrene moiety consumes lithium ions according to the cyclic voltammogram (CV) measurement, as a doping to the PPy binder. Based on the lithium consumption, PPy based Si/graphite electrode doping is quantified at 1.1 electron/pyrene moiety. The PPy binder based electrodes surface are uniform and crack free during lithiation/delithiation, which is revealed through Scanning electron microscope (SEM) imaging.
