dc.description.abstract | Ionic liquid (IL) properties, such as high ionic
conductivity under ambient conditions combined with nontoxicity
and nonflammability, make them important materials for future
technologies. Despite high ion conductivity desired for battery
applications, cation transport numbers in ILs are not sufficient
enough to attain high power density batteries. Thus, developing
novel approaches directed toward improvement of cation transport
properties is required for the application of ILs in energy-storing
devices. In this effort, we used various experimental techniques to
demonstrate that the strategy of mixing ILs with ultrasmall (1.8
nm) nanoparticles (NPs) resulted in melt-processable composites
with improved transport numbers for cations at room temperature.
This significant enhancement in the transport number was attributed to the specific chemistry of NPs exhibiting a weaker cation and
stronger anion coordination at ambient temperature. At high temperature, significantly weakened NP−anion associations promoted
a liquid-like behavior of composites, highlighting the melt-processability of these composites. These results show that designing a
reversible dynamic noncovalent NP−anion association controlled by the temperature may constitute an effective strategy to control
ion diffusion. Our studies provide fundamental insights into mechanisms driving the charge transport and offer practical guidance for
the design of melt-processable composites with an improved cation transport number under ambient conditions. | pl_PL |
