Coupled ion transport in concentrated PEO–LiTFSI polymer electrolytes
Øystein Gullbrekken, Sondre K. Schnell
Abstract
Ionic correlations are important in concentrated PEO–LiTFSI polymer electrolytes. Onsager coefficients are necessary to characterize the ionic motion. Li and TFSI are anticorrelated, increasing the ionic conductivity and Li-ion transport number.
