  3. 2. Wood-Based Nanocellulose In Lithium Ion Batteries and Electrochemical Coatings

    Författare :Hyeyun Kim; Ann M. Cornell; Davide Beneventi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanofibers; lithium ion battery; separator; electro-precipitation; hydrogel; Chemical Engineering; Kemiteknik;

    Sammanfattning : Lithium ion batteries contain diverse functional polymeric materials, e.g. binders and separators. Naturally self-assembled wood cellulose can be disintegrated to nanosized particles with a diversity of morphology by top-down processes, adjusting the manufacturing parameters. LÄS MER

    Sammanfattning : Lithium-oxygen batteries, also known as Lithium-air batteries, could possibly revolutionize energy storage as we know. By letting lithium react with ambient oxygen gas very large theoretical energy densities are possible. LÄS MER

  5. 4. Oxygen formation in the chlorate process and preparation and deactivation of ozone selective anodes

    Författare :Staffan Sandin; Ann M. Cornell; Paul Christensen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATO; EOP; ozone; electrode preparation; elec- trode deactivation; hypochlorite; chlorate; oxygen; chromium VI ; sodium dichromate; electrocatalysis; catalysis; Chemical Engineering; Kemiteknik;

    Sammanfattning : This thesis presents experimental studies concerning two differ-ent electrolytic processes. One part deals with the electrochemicalformation of ozone and focuses on the preparation and deactiva-tion of a highly ozone-selective metal oxide anode (NATO - nickeland antimony doped tin oxide).
