    Abstract : Surface film formation at the electrode/electrolyte interface in lithium-ion batteries has a crucial impact on battery performance and safety. This thesis describes the characterisation and treatment of electrode interfaces in lithium-ion batteries. READ MORE

  2. 2. All silicon lithium-ion batteries

    University dissertation from Uppsala universitet

    Author : Chao Xu; Torbjörn Gustafsson; Kristina Edström; Daniel Brandell; Ola Nilson; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Lithium-ion batteries have been widely used as power supplies for portable electronic devices due to their higher gravimetric and volumetric energy densities compared to other electrochemical energy storage technologies, such as lead-acid, Ni-Cd and Ni-MH batteries. Developing a novel battery chemistry, ‘‘all silicon lithium-ion batteries’’, using lithium iron silicate as the cathode and silicon as the anode, is the primary aim of this Ph. READ MORE
