  1. 1. Towards Safer Lithium-Ion Batteries

    Författare :Marie Herstedt; Kristina Edström; Martin Winter; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Water and alkali salts in the hydrating and hardened green cement-based materials: Hydration process, moisture content and transport

    Författare :Liming Huang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Formation factor; Electrical conductivity; Moisture transport; Pore structure; Sustainable cement-based materials; Hydration; Alkali salts; Supplementary cementitious materials;

    Sammanfattning : Reducing CO2 emissions in the production of cementitious binder is the most effective way to decrease the environmental impact of the construction industry, so a large amount of supplementary cementitious materials (SCMs) has been used in the green concrete. Both the SCMs and alkali salts in binders influence the hydration process and the structure in hardened cement-based materials. LÄS MER

  4. 3. Tailored Reaction Media for the Synthesis of Subvalent Cluster Compounds

    Författare :Josefin Åkerstedt; Lars Kloo; Sven Lidin; Ulf Gedde; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Inorganic Chemistry;

    Sammanfattning : Different synthetic approaches and modifications to reaction media have been applied in order to find new routes to the synthesis of main-group clusters and transition metal compounds. The focus has been on the Group 15 element bismuth and the transition metal palladium. LÄS MER

  5. 4. Subvalent Cluster Compounds and Synthesis in Alternative Reaction Media

    Författare :Josefin Åkerstedt; Lars Kloo; Mats Johnsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal cluster; Zintl ion; metal-organic sandwich complex; ionic liquid; X-ray diffraction; spectroscopy; crystal structure; Inorganic Chemistry;

    Sammanfattning : With the aim of finding alternative reaction media for the synthesis of subvalent main group and transition metal cluster compounds, traditionally made through solid state reactions or in superacidic media, different alternative reaction media have been explored in this work. Room-temperature ionic liquids are amongst the more unconventional reaction media used. LÄS MER

  7. 5. High Temperature Corrosion of Stainless Steels - The Effects of Chloride Salts and SO2(g)

    Författare :Sofia Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : AbstractThe high corrosion rate of superheaters in waste- and biomass- fired plants is often linked to the presence of alkali chlorides. One way to mitigate the corrosion is to replace the superheater material with more corrosion- resistant materials. Another way is to change the corrosive environment by introducing fuel additives.
