2. 21. Structural Lithium-ion battery: Multiphysics modeling of mechanical and electrochemical phenomena

   Author : Johanna Xu; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

   Abstract : The quest for lighter materials and structures to reduce climate impacts in the automotive industry has paved the way for multifunctional solutions. Mass saving on a system level can be achieved by materials or structures having more than one primary function, thus reducing the number of components used. READ MORE

4. 22. RVE generation and computational homogenization of structural battery electrolytes

   Author : Vinh Tu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochemical transport; structural battery electrolyte; Li-ion based structural batteries; computational homogenization; RVE generation;

   Abstract : The structural battery is multifunctional in the sense that it is able to carry mechanical loads, and at the same time store and deliver energy. This is made possible due to carbon fibers' ability to act not only as structural reinforcement materials, but also as electrode components. READ MORE

5. 23. On Modeling and Optimal Control of Modular Batteries: Thermal and State-of-Charge Balancing

   Author : Faisal Altaf; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex optimization; converters; electrified vehicles.; model predictive control; thermal balancing; SOC balancing; battery control; Modular batteries;

   Abstract : There has in recent years been an increasing interest in battery-powered electrified vehicles (xEVs) to reduce carbon footprint of transportation and the dependence on fossil fuels. Since the battery pack of xEVs is one of the most expensive but a key component in the powertrain, the battery lifetime is an important factor for the success of xEVs. READ MORE

6. 24. Cognitive abilities - aspects of structure, process and measurement

   Author : Berit Carlstedt; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cognitive abilities; factor models of intelligence; Enlistment battery; hierarchical models; item sequencing; construct validity; differentiation hypothesis; test evaluation; structural equation modeling;

   Abstract : The overall purpose of the thesis is to describe the development of the Swedish system of measuring cognitive abilities applied at enlistment of conscripts. The Enlistment Battery has been used for more than fifty years to classify 18-year old men into military positions for their compulsory service. READ MORE

7. 25. Experimental Characterization of Electrodes and Multi-Scale Modeling of Swelling Induced Stresses in Lithium-ion Batteries

   Author : Priyank Gupta; Peter Gudmundson; Göran Lindbergh; Erik Olsson; Elham Sahraei; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lithium-ion batteries; mechanical characterization; multiscale modeling; homogenization; Solid Mechanics; Hållfasthetslära;

   Abstract : Over the last few decades, rechargeable lithium-ion batteries have been extensively used in portable instruments due to their high energy density and low self-discharge rate. Recently, lithium-ion batteries have emerged as the most promising candidate for electric vehicles and stationary energy storage. READ MORE
