(February 2016) Prof. Lou Madsen
and colleagues have just published their work “Highly Conductive and Thermally Stable Ion Gels with Tunable Anisotropy and Modulus
” in the high-impact journal, Advanced Materials
. This publication describes a new “ion gel” electrolyte based on a Kevlar®-like polymer and an ionic liquid. This gel has high conductivity and widely tunable stiffness, properties required to build safe and practical rechargeable batteries that use Li-metal electrodes. Such batteries have much higher energy density than conventional Li-ion batteries. Read more about these gels in an article appearing on the VT website here
, or link to the publication here
This work was spearheaded by PhD student Ying Wang in Prof. Madsen’s group, and involves international collaborations with the polymer chemistry group of Prof. Theo Dingemans at Delft University in the Netherlands and the electromaterials group of Prof. Maria Forsyth at Deakin University in Melbourne, Australia.
