    Sammanfattning : Energy and material flows associated with portable and industrial rechargeable batteries have been quantified in a life-cycle perspective, as guidance for development of battery systems. The study included portable batteries based on nickel-cadmium, nickel-metal hydride and lithium-ion. LÄS MER

  3. 3. Assessment of safety characteristics for Li-ion battery cells by abuse testing

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Carl Fredrik Larsson; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; overcharge; Lithium-ion; toxic gases; abuse test; thermal runaway; short circuit; safety; battery; fire;

    Sammanfattning : Despite the many advantages with lithium-ion batteries there can be disadvantages in form of safetyissues. In an abuse situation a Li-ion cell can undergo a thermal runaway releasing excessive heat,flammable and toxic gas emissions and eventually accompanied by dissembling/explosion and fire. LÄS MER

  4. 4. Integration of Battery and Hydrogen Storage with a Grid-Connected Photovoltaic System in Buildings

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Yang Zhang; Jinyue Yan; Jianzhong Wu; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaic; Grid; Building; Battery; Hydrogen Storage; Operation Strategy; Optimization; Energiteknik; Energy Technology;

    Sammanfattning :     The integration of Photovoltaic (PV) with buildings changes the previous electricity consumers into prosumers. The reduced PV subsidies and the grid stable operation requirements are pushing prosumers from direct exportation to self-consumption of the produced electricity. LÄS MER

  5. 5. Preparation and Characterization of Electrochemical Devices for Energy Storage and Debonding

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Simon Leijonmarck; Göran Lindbergh; Ann Cornell; Leif Nyholm; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesives; carbon fiber; debonding; delamination; electropolymerization; flexible battery; lithium-ion battery; paper battery;

    Sammanfattning : Within the framework of this thesis, three innovative electrochemical devices have been studied. A part of the work is devoted to an already existing device, laminates which are debonded by the application of a voltage. LÄS MER
