Recent Advancements on Biopolymer‐ Based Flexible Electrolytes for Next‐Gen Supercaps and Batteries: A Brief Sketch

Abstract

Abstract With a huge upsurge in the energy requirements all over the world, development of energy storage devices with high safety standards without compromising the ecological aspects has become the need of the hour, that propelled the scientific community to search for alternative yet promising sources of energy that would prevent the exhaustion of natural resources. Numerous attempts have been undertaken to utilize the renewable biopolymers in the evolution of solid‐ state electrolytes, as a substitute for liquid electrolytes which are prone to cause leakage leading to hazardous accidents. Despite strenuous efforts, it is still challenging to strike a right balance between the biopolymer elements and the conducting additives. In this review, we aim to lay out a recap on the progress achieved in recent times by employing biopolymers as electrolyte components and its future prospects, that would assist the researchers across the globe to inch one step closer in their quest to find the best electrolyte system for flexible electronics.
