The Impact of Nanoparticle Structuring on the Ionic Conductivity in Liquids
The development of new battery materials is closely tied to our success in nanostructuring these materials or, in other words, how well we are able to incorporate the nanoparticles into the surrounding phases that conduct ions or electrons.
The authors of the article – including among others Mr. Marjan Bele, PhD, from the Laboratory for Materials Electrochemistry – have shown that the formation of the fractal structure of silicon dioxide colloidal particles significantly increases ionic conductivity in the presence of lithium salts in solution. Based on in situ measurements during the formation of the fractal structure, they were able to explain the mechanism of adsorption and dissociation of ionic pairs which significantly affect conductivity.
The article was published in the Journal of the American Chemical Society, (impact factor 9).
