Green Synthesis of Copolymer Electrolytes for Lithium Batteries Catalyzed by an Ecocatalyst Maghnite-H+

The ideal electrolyte material for a solid-state battery would have the ionic conductivity of a liquid, the mechanical properties of a solid, and the formability of a commodity thermoplastic.

The ionic conductivity changed with the molecular weight of the polymer, it varies inversely with the glass transition temperature. In our study, to achieve high ionic conductivity, we synthesize copolymer PDMS/PEO as polymer electrolytes by a simple method.

One step of catalytic ring opening polymerization using Maghnite-H+ (Mag-H+), a montmorillonite sheet silicate clay exchanged with protons. It is preferred for its many advantages: a very low purchase price compared to other catalysts, the easy removal of the reaction mixture.
