    Abstract : Li-ion batteries are currently the most efficient technology available for electrochemical energy storage. The technology has revolutionized the portable electronics market and is becoming a corner stone for large scale applications, such as electric vehicles. READ MORE

  3. 3. Environmental Assessment of Battery Systems: Critical Issues for Established and Emerging Technologies

    Author : Carl Johan Rydh; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photovoltaic cells; battery; environmental indicators; substance flow analysis; energy analysis; metal recycling; energy efficiency; materials management; rechargeable; life cycle assessment; renewable energy;

    Abstract : 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. READ MORE

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

    Author : Carl Fredrik Larsson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; overcharge; Lithium-ion; toxic gases; abuse test; thermal runaway; short circuit; safety; battery; fire;

    Abstract : 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. READ MORE

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

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

    Abstract :     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. READ MORE
