  2. 6. All silicon lithium-ion batteries

    Author : Chao Xu; Torbjörn Gustafsson; Kristina Edström; Daniel Brandell; Ola Nilson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Lithium-ion batteries have been widely used as power supplies for portable electronic devices due to their higher gravimetric and volumetric energy densities compared to other electrochemical energy storage technologies, such as lead-acid, Ni-Cd and Ni-MH batteries. Developing a novel battery chemistry, ‘‘all silicon lithium-ion batteries’’, using lithium iron silicate as the cathode and silicon as the anode, is the primary aim of this Ph. READ MORE

  4. 7. Highly Concentrated Electrolytes for Lithium Batteries : From fundamentals to cell tests

    Author : Viktor Nilsson; Kristina Edström; Patrik Johansson; Erik Berg; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; SEI; Highly concentrated electrolyte; Al corrosion; Li metal battery;

    Abstract : The electrolyte is a crucial part of any lithium battery, strongly affecting longevity and safety. It has to survive rather severe conditions, not the least at the electrode/electrolyte interfaces. READ MORE

  5. 8. Computational Analysis of Gas Flow and Heat Transport Phenomena in Ducts Relevant for Fuel Cells

    Author : Jinliang Yuan; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; PEMFC.; SOFC; CFD; Duct; Transport Process; Fuel Cell; Heat Transfer; Gas Flow; Numerical Simulation; Analysis;

    Abstract : The thesis concerns modeling, simulation and numerical analysis of heat and mass transport, and fluid flow in ducts of both solid oxide fuel cells (SOFCs) and proton exchange membrane fuel cells (PEMFCs). The unique fuel cell boundary conditions (thermal, mass) for the flow ducts in fuel cells are identified and applied. READ MORE
