1P-392 : Polyaniline-grafted Chitosan as a binder for Silicon Anode in Lithium-ion Batteries

Chitosan is the most abundant organic compound found in marine sources like crustaceans and mollusks. It’s biodegradable and biocompatible which exhibit good mechanical strength and adhesion. Conducting properties of polyaniline (PANI) have played a substantial role in energy storage and conversion devices. We prepared a chitosangrafted-polyaniline (Ch-g-PANI) by oxidative-radical copolymerization of aniline onto chitosan, and investigated its application as a novel polymeric binder for Si anode. Synthesis, characterization and electrochemical properties of the grafted polymer will be discussed in details.
