ABSTRACT
Conducting polymers have been extensively studied during the past few decades in lithium batteries due to their outstanding properties such as good mechanical strength, easy fabrication, environmental stability, electronic conductivity and high columbic efficiency so as to be cycled a number of times with degradation. Metal chalcogenides are known to show high specific energy and thus are used in alkali metal batteries, but lack of conductivity and cyclability limits its application for commercial application. This chapter introduces series of intercalation of metal chalcogenides into the conducting polymers to produce conductive nanocomposites for possible applications in Li-ion batteries. It also highlights the role of chalcogenide doped conducting polymers in enhancing battery performance. This chapter presents the various strategies involved in conducting polymer/metal chalcogenide synthesis. The hybrid chalcogenide/conducting polymer composites exhibit high energy and power density with enhancement in the life cycle and thus improved electrochemical performance.
