  2. 1. All-organic aqueous Na-ion energy storage devices

    Author : Martin Karlsmo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid supercapacitor; battery; battery supercapacitor hybrid; aqueous electrolyte; All-organic; Na-ion capacitor; energy storage;

    Abstract : Development of all-organic aqueous energy storage devices (ESDs) is a promising pathway towards meeting the needs of technically medium/low-demanding electrical applications. These ESDs should favour low cost, low environmental impact, and safety, and thus complement high voltage and energy/power dense storage such as lithium-ion batteries. READ MORE

  4. 2. Ions in cold electrostatic storage devices

    Author : Peter Reinhed; Henning Schmidt; Henrik Cederquist; Jason Greenwood; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Atom- och molekylfysik; fysik; Physics;

    Abstract : We have constructed a compact purely electrostatic ion-beam trap, ConeTrap, which we have mounted inside a double-walled vacuum chamber. In the inner vacuum chamber, we can obtain ultra-high vacuum (UHV) conditions and reach thermal equilibrium at well controlled temperatures down to 10 K. READ MORE

  5. 3. Hybrid energy storage systems : Capacity optimization and environmental implication of hybrid energy storage systems in renewable power systems

    Author : Yang Jiao; Daniel Månsson; Alfred Rufer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Electricity production contributes a large share of greenhouse gas emissions that lead to climate change. At present, power generation in many parts of the world still heavily depends on fossil fuels. To prevent global warming, the electricity sector is supposed to transition from the current fuel mix to renewable energy sources. READ MORE

  6. 4. Exploring Devices for Molecular Solar Thermal Energy Storage Systems

    Author : Zhihang Wang; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar energy; photochromic molecule; dihydroazulene vinylheptafulvene photoswitches; energy conversion; norbornadiene quadricyclane photoswitches; energy storage;

    Abstract : The sun is considered to be one of the most abundant and renewable sources of energy. During recent last decades, technologies for solar energy capture and storage have been significantly investigated. An attractive way to store solar light, is to use photochromic molecules that can capture and store solar energy in chemical bonds. READ MORE

  7. 5. Computational Studies of 2D Materials : Application to Energy Storage and Electron Transport in Nanoscale Devices
