  1. 1. Building Sustainable Batteries : Organic electrodes based on Li- and Na-benzenediacrylate

    Författare :Alina Oltean; Daniel Brandell; Leif Nyholm; Steven Renault; Martin Sjödin; Robert Dominko; Uppsala universitet; []
    Nyckelord :Organic Electrode Materials; Li-ion Batteries; Na-ion Batteries; Calendaring; Recycling Process; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : As possible alternatives to the conventional inorganic Li- or Na-ion battery electrode materials, organic compounds have recently drawn considerable attention. However, major challenges such as poor electronic conductivity, solubility in battery electrolyte or fast capacity decay of the resulting electrochemical cells are some of the reasons that hold these compounds back from becoming commercial solutions in the energy system.

  2. 2. Sustainable recycling of Li-ion batteries

    Författare :Jędrzej Piątek; Adam Slabon; Tetyana Budnyak; Reza Younesi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; batteries; recycling; metal recovery; adsorption; electrochemistry; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : Lithium-ion batteries (LIBs) play a key role in today’s energy storage sector, finding applications in everyday use electronic devices, like smartphones, laptops or electric vehicles. Despite very good properties, such as high electric capacity and high number of charge-discharge cycles, eventually each battery in the world will be disposed and stored in a landfill, waiting for the opportunity to be recycled.

  3. 3. Molten Salt Electrolytes for Calcium Batteries

    Författare :Johanna Timhagen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Batteries; Metal anodes; Molten salt electrolytes; Calcium;

    Sammanfattning : Batteries are in higher demand than ever before as well as increased requirements in terms of energy and power density. The desire for higher energy density has meant that electrolytes are pushed above their electrochemical stability limits and hence they decompose, but typically this is under control and a new beneficial phase is created at the electrode surface; the solid electrolyte interphase (SEI).

  4. 4. Characterization and Dissolution of HEV NiMH Batteries

    Författare :Kristian Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Materials Recycling; Nickel tetracarbonyl; Selective dissolution; Nickel metal hydride; Characterization; Mond; Batteries;

    Sammanfattning : The recycling of batteries is an important issue in a sustainable society where materials recycling of complex products is a necessity. Without an efficient recycling there will be an unnecessary loss of both materials and energy due to inefficient or non-existent recycling. LÄS MER

  5. 5. Structural and Electrochemical Relations in Electrode Materials for Rechargeable Batteries

    Författare :Viktor Renman; Kristina Edström; Mario Valvo; Cesar Pay Gómez; Mats Johnsson; Helmer Fjellvåg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; batteries; electrochemical energy storage; oxohalides; conversion; alloy; pyrosilicate; CuHCF; MnHCM; XRD; XANES; in operando; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : Rechargeable batteries have already conquered the market of portable electronics (i.e., mobile phones and laptops) and are set to further enable the large-scale deployment of electric vehicles and hybrid electric vehicles in a not too distant future. LÄS MER
