  2. 6. Structure and Dynamics in Ionic Liquid and Highly Concentrated Electrolytes

    Author : Filippa Lundin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ionic Liquid; Electrolytes; SAXS; Highly concentrated electrolytes; QENS;

    Abstract : The electrolyte is a crucial part of a battery in terms of longevity and safety. However, the state-of-the-art electrolytes for lithium-ion batteries are based on organic solvents and Li-salts (typically 1M concentration) and are known to be volatile and to degrade at higher temperature.

  4. 7. 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

  5. 8. Ionic liquids in bio-refining : synthesis and applications

    Author : John Gräsvik; Jyri-Pekka Mikkola; Bertil Eliasson; Manu Lahtinen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ionic liquid; Joniska vätskor;

    Abstract : Fossil fuel resources are not limitless so alternative renewable recourses are needed to fill the void that inevitably will be created once the supplies of this resource start do dwindle. Biomass has the potential to fill this void. READ MORE

  6. 9. Theoretical Studies Using Simple Ionic Liquid Models

    Author : Hongduo Lu; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Room Temperature Ionic Liquids; Coarse-Grained Models; Differential Capacitance; Monte Carlo; Classical Density Functional Theory; Room Temprerature Ionic Luqids; coarse-grained model; differential capacitance; Monte Carlo simulation; Classical Density Functional Theory;

    Abstract : Room Temperature Ionic Liquids (RTILs) are organic salts that melt below 100 degrees Celsius. The advantages of RTILs, such as high ionic concentrations and low melting points, promote several potential applications. For instance, RTILs could be utilized in manufacturing energy storage devices, and as efficient solvents. READ MORE

  7. 10. Cellulose processing in ionic liquid based solvents

    Author : Carina Olsson; Chalmers tekniska högskola; []
