  2. 1. Lithium-ion batteries for off-grid PV-systems

    Author : Fabian Benavente; Göran Lindbergh; Anders Olof Lundblad; Saul Cabrera; Daniel Abraham; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion batteries; aging; partial cycles; DVA; EIS; NCA; stationary energy systems; PV systems; rural electrification.; Chemical Engineering; Kemiteknik;

    Abstract : This thesis provides a comprehensive and detailed analysis on the effect ofthe battery operation strategy on the lifetime of commercial lithium-ionbatteries and on the economics of off-grid photovoltaic (PV)-batterysystems.Lithium-ion batteries play a key role in the transition to a fossil-freesociety.

  4. 2. State-of-Health Estimation of Li-ion Batteries: Ageing Models

    Author : Jens Groot; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; State-of-health; lithium-ion battery; EV; PHEV; cycle life test; impedance spectroscopy; DVA; battery testing; ICA; battery model; HEV;

    Abstract : Significant research efforts are being made to understand, and ultimately mitigate, thedegradation of Li-ion batteries upon usage. Currently, battery ageing models are used inorder to optimise the battery usage and to achieve robust battery solutions. READ MORE

  5. 3. State-of-Health Estimation of Li-ion Batteries: Cycle Life Test Methods

    Author : Jens Groot; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EV; DVA; ICA; cycle life test; HEV; battery testing; State-of-health; battery model; PHEV; lithium-ion battery; impedance spectroscopy;

    Abstract : Despite a rapid development, cost, performance and durability of the energy storage system are still a hindrance for a wide commercialisation of heavy-duty hybrid electric vehicles (HEV). The purpose of the work presented in this thesis is to investigate how different load cycle properties affect the cycle life and ageing processes of Li-ion cells developed for use in HEVs. READ MORE

  6. 4. Jill Bilcock : Revealing the Invisible Artist. Recognising the creative contributions of film editors to filmmaking through biographical documentary film

    Author : Axel Grigor; Patricia FitzSimons; Nico Meissner; Joanna Callaghan; Kath Dooley; Högskolan Dalarna; []
    Keywords : HUMANIORA; HUMANITIES; Film Editing; Film Editor; Film Production; Filmmaking; Motion Pictures; Motion Picture Editing; Documentary; Film Art; Film History; Biography; Jill Bilcock; Australia; Hollywood; Filmklippning; Filmklippare; Filmproduktion; Film; Filmkonst; Dokumentärfilm; Biografi; Jill Bilcock; Australien; Hollywood;

    Abstract : Film editing is recognised as the conceptual innovation that, at the dawn of the twentieth century, helped transform the novelty of moving images into cinema. Despite this acknowledgment, misconceptions about the art form linger. READ MORE

  7. 5. Fast Dynamic Processes in Solution Studied by NMR Spectroscopy

    Author : Mária Šoltésová; Jozef Kowalewski; Jan Lang; Gyula Batta; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear magnetic resonance; Dynamics; Ethanol; Cryptophanes; Saccharides; Nukleární magnetická rezonance; dynamika; ethanol; kryptofan; sacharidy; fysikalisk kemi; Physical Chemistry;

    Abstract : Nuclear magnetic resonance (NMR) spectroscopy is capable to deliver a detailed information about the dynamics on molecular level in a wide range of time scales, especially if accompanied by suitably chosen theoretical tools. In this work, we employed a set of high-resolution NMR techniques to investigate dynamics processes in several weakly interacting molecular systems in solution. READ MORE
