  2. 1. New anions for lithium battery electrolytes

    Author : Johan Scheers; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Batteries; ab initio; electrolytes; Raman spectroscopy; anions; DFT; ionic liquids; lithium salts;

    Abstract : Energy storage is crucial to realize a new global energy paradigm based on renewable energy sources. Batteries are well suited this need, with the advantages of being mobile and potentially environmentally benign. READ MORE

  4. 2. Lithium titanate as anode material in lithium-ion batteries : -A surface study

    Author : Tim Nordh; Kristina Edström; Daniel Brandell; Carl Tengstedt; Carla Puglia; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; titanate battery anode SEI; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : The ever increasing awareness of the environment and sustainability drives research to find new solutions in every part of society. In the transport sector, this has led to a goal of replacing the internal combustion engine (ICE) with an electrical engine that can be powered by renewable electricity. READ MORE

  5. 3. Functional Binders at the Interface of Negative and Positive Electrodes in Lithium Batteries

    Author : Fabian Jeschull; Daniel Brandell; Gerrit Boschloo; Uppsala universitet; []

  6. 4. Development of a Novel Method for Lithium-Ion Battery Testing on Heavy-Duty Vehicles

    Author : Pontus Svens; Mårten Behm; Göran Lindbergh; Per Alvfors; Anders Malmqvist; KTH; []
    Keywords : Lithium-ion battery; HEV; field testing; heavy-duty vehicles;

    Abstract : Increasing demands for lower environmental impact from vehicles, including heavy-duty vehicles, have driven several vehicle manufacturers to consider adding hybrid electrical vehicles (HEV’s) to the product portfolio. Present research on batteries for HEV’s is mainly focused on lithium-ion battery chemistries, since lithium-ion batteries has the most promising technical potential compared to other types of batteries.
