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

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

    Sammanfattning : 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. LÄS MER

    Sammanfattning : 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. LÄS MER

  4. 3. Microrheology of Concentrated Protein Solutions

    Författare :Tommy Garting; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microrheology; Dynamic Light Scattering; Protein; Pegylation; Viscosity;

    Sammanfattning : The behavior of concentrated protein solutions is of general high interest due to implications in, for example, biological systems and medical applications. It is necessary to investigate the rheological properties of such systems to understand how parameters, such as stability, are affected by the high concentrations. LÄS MER

  5. 4. Design and analysis of a fault-tolerant fractional slot PMSM for a vehicle application

    Författare :Christian Dubar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saturation; Permanentmagnet synchronousmachine PMSM ; Fault-tolerance; windings; Concentrated; Fractional slot; Unbalanced operation;

    Sammanfattning : The permanent magnet synchronous motor (PMSM) is an interesting alternative for an electric motor drive system in automotive applications, due to to the high efficiency requirement; as only a limited amount of energy can be stored in the relatively expensive battery. Another advantage is the high torque and power density a PMSM can achieve since it is very important to save especially space but also weight in vehicle applications. LÄS MER

  7. 5. Structure and Dynamics in Ionic Liquid and Highly Concentrated Electrolytes

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

    Sammanfattning : 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.
