2. 11. From Multiple Scale Modeling to Multiscale-Modeling

   Author : Fabian Årén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-scale modeling; AIMD; DFT; MD; lithium-ion batteries; electrolytes; machine learning;

   Abstract : To power a sustainable future, interest in battery research and technology is at an all time high. In order to enable a transition to green tech many applications, such as the automotive industry, is in need of higher power densities, energy densities, longer life-times, and safer batteries.

4. 12. Dynamic Structure Discovery and Ion Transport in Liquid Battery Electrolytes

   Author : Rasmus Andersson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ion transport mechanisms; electrolytes; dynamic structure discovery; lithium-ion batteries; statistical physics;

   Abstract : The lithium-ion battery (LIB), the realisation of which earned the Nobel Prize in Chemistry 2019, has since its 1991 commercialisation become the dominant energy storage technology first for cell phones and other mobile electronics, then for power tools and other domestic appliances, and currently for electric cars and other vehicles. However, many applications would still benefit from higher power and energy densities, longer life-lengths and safer batteries. READ MORE

5. 13. Innovative Electrolytes and Electrodes for Sodium-Ion Batteries

   Author : Damien Monti; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electrolytes; Sodium-ion batteries; ionic liquids; electrodes;

   Abstract : Batteries are expected to be masterpieces for future large-scale energy storage, but the emergence of ecological and financial concerns has forced us to think about complementary battery technologies to the today outstanding lithium-ion batteries (LIBs). Therefore, the sodium-ion battery (SIB) is a concept worth studying - especially for large-scale applications due to the abundance of sodium as an element, the overall low cost anticipated, and the similarities with LiBs, which should ease a technology change.

6. 14. In-situ Investigations of Lithium-Sulfur Batteries

   Author : Matthew Sadd; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : As the demand for high energy-density storage devices increases, we must look beyond the current state of the art technology, the lithium-ion battery. Lithium-ion battery technologies are approaching their theoretical limit in terms of capacity, and now that the demand for longer-range electric vehicles (EVs) and the implementation of grid storage is increasing, we need to provide technologies that can go beyond what is currently possible.
