Abstract

In this work, we report methods to quantify and minimize the interfacial resistance for Li ion transport, R _interface , between a model polymer electrolyte, poly(ethylene oxide) + LiCF ₃ SO ₃ (PE), and a model Li ⁺ -conducting ceramic electrolyte, LICGC from Ohara Corporation. By constructing a PE-ceramic-PE trilayer cell, we found R _interface to be very large, 1.2 kω·cm ² at 30 °C, accounting for 66% of the total trilayer cell resistance. When dimethyl carbonate, a loose-binding solvent of Li ⁺ , was introduced into the trilayer, R _interface decreased to essentially zero. As a result, a composite electrolyte with carbonate plasticizers wherein 40 vol % ceramic particles were dispersed in the polymer showed extraordinary room-temperature conductivity of approximately 10 ^-4 S/cm, 3 orders of magnitude higher than that of the dry composite electrolyte. This discovery can be used as guidance in designing composite electrolytes to achieve synergistic effects.
