Abstract
Abstract In this paper, the facile synthesis and characterization aspects of PEDOT:PSS has been presented, in the context of energy storage device technology. PEDOT/PSS particles were synthesized via chemical oxidative polymerization to improve the electrical conductivity. The mechanism for this conductivity enhancement was studied through various chemical and physical characterizations. The structural characterization establishes that all the samples have high surface area and are highly crystalline, showing 3–4 nm spherical nanoparticles with the smoother surface. The electrical conductivity of measured thin film reached 6.23 × 10 −6 ℧ cm −1 . The use of the PEDOT:PSS as a binders will surely be helpful for scaling up the energy storage technology like high electrical conductivity, the ability for aqueous processing, electrochemical performance, good electrochemical stability and shows good binding ability. It also helps to protect the energy storage devices against electrode particle cracking, solid electrolyte interface (SEI), dendrite formation or lithium plating.
