  2. 11. Towards Safer Lithium-Ion Batteries

    Author : Marie Herstedt; Kristina Edström; Martin Winter; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; lithium-ion batteries; photoelectron spectroscopy; surface film; thermal stability; electrolyte additive; graphite; lithium iron phosphate; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

    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

  4. 12. Corrosion and Surface Studies of Stainless Steel and Chromium Carbide Thin-Films

    Author : Jonas Högström; Leif Nyholm; Kristina Edström; Patrik Schmutz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; corrosion; electrochemistry; thin film; stainless steel; passive film; chromium carbide; carbon oxidation; surface; depth profile; XPS; SEM; EQCM; sputtering;

    Abstract : Although the passive films that form on stainless steels have been extensively studied, the concentration depth profiles are not fully understood. Their thinness makes passive films hard to study, but angle-resolved X-ray photoelectron spectroscopy (ARXPS) is a non-destructive technique that can be used to obtain depth information. READ MORE

  5. 13. Titanium-Based Negative Electrode Materials for Rechargeable Batteries : In Search of the Redox Reactions

    Author : Tatiana Koriukina; Kristina Edström; Egbert Figgemeier; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion batteries; sodium-ion batteries; MXenes; perovskite oxides; redox reactions; XPS; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Rechargeable batteries, particularly, lithium-ion batteries (LIBs) have proven to be stable and reliable energy storage devices over the past few decades. The rapid demands regarding battery applications and the pressure to move away from the fossil fuel era drive the search for new materials for better rechargeable batteries for electric vehicles, renewable energy storage, and portable electronics.
