PEO/PVA/LiOH Solid Polymer Electrolyte Prepared via Ultrasound-assisted Solution Cast Method

Post-transition metal/polymer composites for the separation and sensing of alkali metal ions

“…As Li + , Na + and K + present the same valence and close ionic radii for physical separation, the selectivity of the Ga-In composite is related to the specic energy of interaction and stabilization between the ions and the charged domains across the composite. 18,31 The selectivity of the Ga-In composite was also demonstrated to be independent of the driving force, i.e. osmotic pressure in pure diffusion or electric eld in electro-diffusion regime (Fig.…”

“…Here we choose polyvinyl alcohol (PVA) as a hydrophilic, semicrystalline polymer that presents a charged matrix with functional hydroxyl and carbonyl groups providing high conductivity and permeability to both Na + and K + . [31][32][33] Strong interactions between the functional groups of PVA and Li + were also previously reported but were shown to induce intermolecular charge transfer leading to detrimental changes in the physicochemical stability of PVA. 31 Cross-linking or direct coordination with the selective additives are ways to mitigate the weakening of the PVA matrix.…”

Designing Versatile Polymers for Lithium-Ion Battery Applications: A Review

“…Putri et al [ 79 ] recently prepared a PEO/poly(vinyl alcohol) (PVA) blend with lithium hydroxide (LiOH) as a source of Li + cations. The addition of amorphous PVA was determinant to disrupt PEO crystallinity and enhance the SPE conductivity at RT.…”

Innovative Methylcellulose-Polyvinyl Pyrrolidone-Based Solid Polymer Electrolytes Impregnated with Potassium Salt: Ion Conduction and Thermal Properties

“…Recently, solid-state electrolytes (SSEs) have arisen as a technology of significant research and commercial relevance for the storage of electrical energy. Solid polymer electrolytes (SPEs) are a class of SSEs that comprise an inorganic salt dispersed in a polymer host material [ 1 ]. Currently, SPEs are getting particular attention due to a variety of factors, including the development of high-performance materials, better safety concerns, and innovative applications [ 2 , 3 , 4 , 5 ].…”
