Abstract
A colloidal ionic-liquid electrolyte for electrochemical devices is provided. The colloidal ionic-liquid electrolyte includes a room temperature ionic-liquid, a lithium salt, and a ceramic particle phase (powder) including a high dielectric material dispersed in the ionic-liquid electrolyte, wherein the colloidal ionic-liquid electrolyte exhibits enhanced ionic conductivity in the electrochemical device compared to the ionic conductivity of the pure room temperature ionic-liquid. The high dielectric material exhibits a first dielectric constant of about 200 or more, and a first mean particle size of about 2000 nm or less. The enhanced ionic conductivity is observed in the temperature range of about 75° C. to about −60° C. and is more pronounced at colder temperatures. In addition, the colloidal ionic-liquid electrolyte exhibits enhanced non-flammability, enhanced mechanical stability, enhanced thermal stability and suppressed flowability.
