Modeling of Next Generation Battery Electrolytes
Future energy demands require the development of efficient devices for energy storage such as high performance batteries The lithium battery (LB) technology currently clearly outperforms other modern types of rechargeable batteries (alkaline, NiMH etc.) having much higher volumetric and gravimetric capacities. However, here we focus mainly on those technologies even further away: Na, Ca, Mg, and Al-batteries and the new electrolytes needed for these. A special new field is highly concentrated electrolytes. The Condensed Matter Physics (CMP) division at Chalmers has studied energy storage materials at the molecular level since the early 90's, especially the electrolytes needed. This research is made in international collaborations as well as in national, and in close collaboration with industry. We are involved in 2 EU programmes on batteries. Nationally we are funded by both the Swedish Research Council and the Swedish Hybrid Vehicle Centre to perform battery research. Recently several grants from the Swedish Energy Agency were received - some for modeling tasks and some via Swedish Research Council (VR). Our aim is here to computationally model phenomena on a molecular level to understand the underlying physics and chemistry and be able to give efficient feedback to our collaborators and also to be able to assist in the interpretation of various experimental data. In addition the projects are tightly linked with the experimental activities within Chalmers and our international collaborators.
