  4. 12. Lithium-ion Battery Safety - Assessment by Abuse Testing, Fluoride Gas Emissions and Fire Propagation

    Author : Carl Fredrik Larsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fire; thermal runaway; gas emission; gas explosion; propagation; safety; abuse testing; Lithium-ion; cell case explosion; hydrogen fluoride;

    Abstract : Lithium-ion batteries offer high energy and power densities as well as long life time but have a more narrow stability window compared to other battery types and contain reactive and flammable materials. In case of overheating the battery cell can release gas (vent) and, at temperatures of about 150-200 °C, a so called thermal runaway can occur, that is a rapid self-heated temperature increase which is typically accompanied with a large release of smoke and gas, fire and a potential cell case explosion or gas explosion.

  5. 13. Wood-Based Nanocellulose In Lithium Ion Batteries and Electrochemical Coatings

    Author : Hyeyun Kim; Ann M. Cornell; Davide Beneventi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanofibers; lithium ion battery; separator; electro-precipitation; hydrogel; Chemical Engineering; Kemiteknik;

    Abstract : Lithium ion batteries contain diverse functional polymeric materials, e.g. binders and separators. Naturally self-assembled wood cellulose can be disintegrated to nanosized particles with a diversity of morphology by top-down processes, adjusting the manufacturing parameters. READ MORE

  6. 14. Diagnosis of the Lifetime Performance Degradation of Lithium-Ion Batteries : Focus on Power-Assist Hybrid Electric Vehicle and Low-Earth-Orbit Satellite Applications

    Author : Shelley Brown; Göran Lindbergh; Robert Spotnitz; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lithium-ion battery; LixNi0.8Co0.15Al0.05O2; LixMn2O4; LiyC6; ageing; three-electrode measurements; impedance modelling; surface film characterisation; hybrid electric vehicle; low-earth-orbit satellite; litiumjonbatteri; åldring; treelektroduppställning; impedansmodell; ytfilmskarakterisering; hybridfordon; satelliter; Electrochemistry; Elektrokemi;

    Abstract : Lithium-ion batteries are a possible choice for the energy storage system onboard hybrid electric vehicles and low-earth-orbit satellites, but lifetime performance remains an issue. The challenge is to diagnose the effects of ageing and then investigate the dependence of the magnitude of the deterioration on different accelerating factors (e.g. READ MORE

  7. 15. 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
