A review on nano composite polymer electrolytes for high-performance batteries

Abstract

Polymer electrolytes (PEs) are lightweight, flexible, non-flammable solutions and provide a feasible way to replace organic liquid electrolytes because of the safety issues faced by energy storage devices. Inorganic nanofillers are vital in enhancing ionic conductivity by creating additional pathways in polymer-based nanocomposite solid electrolytes. The advances in polymer electrolytes play an essential role in developing the energy storage devices such as batteries. This article briefly summarises the preparation techniques of different polymer electrolytes, developing and focusing on fundamental properties such as surface morphology, electrolyte phases, and the influence of dopants, fillers, and plasticizers on the ionic charge transfer, ionic conductivity, dielectric properties, and transport properties using impedance spectroscopy. We anticipate that gives clear direction for developing energy storage devices.
