Carrageenan-Ionic Liquid Composite: Development of Polysaccharide-Based Solid Electrolyte System

Carrageenan-Ionic Liquid Composite: Development of Polysaccharide-Based Solid Electrolyte System

Abstract

Solid electrolyte system compared to a liquid electrolyte is desirable for some electrochemical applications. Natural polymers like polysaccharides were explored as polymer matrix in the development of solid electrolyte system. Among the polysaccharides screened, k- carrageenan showed promising results. Cyclic voltammetry of the I3 -/I- redox couple in k- carrageenan gel showed improved performance compared to aqueous medium. Composite films of k-carrageenan with KI and I2 as triiodide sources and polymer electrolytes based on k- carrageenan and ionic liquid, 1,3-dimethyl imidazolium iodide (DMII) with I2 were prepared and characterized.

Abstract

Let G be a group and H be a subgroup with H ≠ G. In this paper, we construct a group using G – H. This paper also presents several properties of this group. Read More
