Ionic Conductivity of Composite Polymer Electrolyte: Clarifying the Role of the Interface with Nonconductive Particles.

ABSTRACT: Solid-state electrolytes are considered as an enabler for batteries with extended energy density. Polymers are promising materials but show insufficient ion transport properties, a limitation that can be lifted by the fabrication of composite polymer electrolytes. Nevertheless, the role of the inorganic particles in tuning the conduction properties is often unclear, especially when inert fillers are added. Herein, poly(trimethylene carbonate) and alumina particles: α-Al₂O₃, γ-AlOOH and γ-Al₂O₃ are mixed by two dispersion methods to prepare a series of composites. The correlations between microstructure, surface chemistry, and transport properties are studied, which are evaluated by combining synchrotron nanotomography, solid-state nuclear magneti
