Multifunctional materials and devices offer significant weight and/or volume savings and this is important in mobile products such as portable electronics, electrical/hybrid vehicles, etc. One example of multifunctional device is one which possesses a combination of structural performance and energy storage ability, i.e. a structural energy storage device. This proposal aims to improve our understanding of multifunctional electrolytes which are essential components of structural storage devices, specifically structural supercapacitors. Preparation of a multifunctional electrolyte is a complex issue. Previous studies carried out by the proposers have shown that electrolytes with a bicontinuous structure have a promising set of properties. The proposed SANS experiment will help us understanding how the bicontinuous phases form and this is essential to be able to develop existing systems.
