Fast Li-ion conduction in poly(ethylene carbonate)-based electrolytes and composites filled with TiO sub(2) nanoparticles

We have found remarkable ion-conductive properties in a novel polymer electrolyte composed of poly(ethylene carbonate) and Li bis-(fluorosulfonyl) imide. The self-diffusion coefficient of Li-ions exceeded 10 super(-7) cm super(2) s super(-1) and the Li transference number was estimated to be more th...

Zusammenfassung:We have found remarkable ion-conductive properties in a novel polymer electrolyte composed of poly(ethylene carbonate) and Li bis-(fluorosulfonyl) imide. The self-diffusion coefficient of Li-ions exceeded 10 super(-7) cm super(2) s super(-1) and the Li transference number was estimated to be more than 0.8 in composites filled with only 1 wt% of TiO sub(2) nanoparticles.
