  2. 21. Ionic Liquid Based Electrolytes for High-Temperature Lithium-Ion Batteries

    Author : Manfred Kerner; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMITFSI; EMIFSI; electrolyte; ionic liquid; lithium-ion battery; high-temperature stability; LiFSI;

    Abstract : Today, lithium-ion batteries (LIBs) are ubiquitous in mobile phones, laptops, and other portable devices. The research community strives to further improve the LIB to increase electric driving distance and efficiency of both hybrid electric vehicles (HEVs) and fully electric vehicles (EVs). READ MORE

  4. 22. Preparation and characterization of perovskite structure lanthanum gallate and lanthanum aluminate based oxides

    Author : Shuai Li; Bill Bergman; Mogens Mogensen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lanthanum gallate; lanthanum aluminate; ceria; composite; solid oxide fuel cell; electrolyte; polymer complexing.; Functional materials; Funktionella material;

    Abstract : The present work was initiated to study the synthesis and properties of lanthanum gallate based oxides as intermediate temperature electrolyte for solid oxide fuel cells. The wet chemical method, polymer complexing route, was used to prepare the precursor powders. READ MORE

  5. 23. Exploring Organic Dyes for Grätzel Cells Using Time-Resolved Spectroscopy

    Author : Ahmed M. El-Zohry; Burkhard Zietz; Ana Morandeira; Leif Hammarström; Eric Vauthey; Uppsala universitet; []
    Keywords : Laser spectroscopy; DSSCs; DSC; Electron dynamics; Deactivation processes; Isomerization; Twisting; TICT; Quenching by protons; Semiconductor; Electrolyte; Electron injection; Regeneration; Recombination; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi; Kemi med inriktning mot kemisk fysik; Chemistry with specialization in Chemical Physics;

    Abstract : Grätzel cells or Dye-Sensitized Solar Cells (DSSCs) are considered one of the most promising methods to convert the sun's energy into electricity due to their low cost and simple technology of production. The Grätzel cell is based on a photosensitizer adsorbed on a low band gap semiconductor. READ MORE

  6. 24. On the fluid mechanics of electrochemical coating and spray painting

    Author : Pedro Olivas; KTH; []
    Keywords : mass transfer; electrochemical coating; ion transport; forced convection; diffusion; magnetoelectrolysis; electrolyte; limiting current; numerical simulation;

    Abstract : Finite-volume methods have been used for modeling of fluidflows involved in forced convection electrochemical coating androtating spray painting systems. Electrodeposition on a singlecircular cylinder under forced convection for Reynolds numbers10 and 200 was simulated. READ MORE

  7. 25. Molecular structure, interactions, and dynamics of novel Li-battery electrolytes

    Author : Luis Aguilera Medina; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAXS; Raman scattering; imidazolium; NSE; lithium ion battery; electrolyte; organic solvent; pyrrolidinium; TFSI; ionic liquid;

    Abstract : Lithium-ion batteries are one of the most promising candidates for energy storage in sustainable technologies such as electro-mobility or renewable energy systems. However, at present they are incapable to compete with the combustion engine to power vehicles in terms of capacity, price, and safety. READ MORE
