Abstract

Composite solids polymer electrolytes (SPEs) based on Pluronic block copolymers, PEOxb-PPOyb-PEOx, and silicate organic–inorganic component (OIC) formed in situ have been synthesized and characterized using solid-state NMR, Raman spectroscopy, differential scanning calorimetry (DSC), small-angle X-ray scattering (SAXS), rheology, and electrochemical measurements. Raman spectroscopy, DSC, and rheological data reveal that the block copolymer and OIC are intermixed in the composite SPEs, and the degree of intermixing determines the SPE properties. Comparison of the SAXS and electrochemical results leads us to conclude that ordering in block copolymer-based composite SPEs is not a crucial parameter for the improved conductivity, while the combination of the ratios of the SPE components and their intermixing gives rise to extended interfaces that control the electrochemical performance.
