  1. 1. All silicon lithium-ion batteries

    Författare :Chao Xu; Torbjörn Gustafsson; Kristina Edström; Daniel Brandell; Ola Nilson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 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. LÄS MER

  3. 2. Imine/azo-linked microporous organic polymers : Design, synthesis and applications

    Författare :Chao Xu; Niklas Hedin; Dave Adams; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microporous organic polymers; CO2 capture and separation; post-modification; chemisorption; heterogeneous catalysis; Materials Chemistry; materialkemi;

    Sammanfattning : Microporous organic polymers (MOPs) are porous materials. Owing to their high surface area, tunable pore sizes and high physicochemical stability, they are studied for applications including gas capture and separation and heterogeneous catalysis. In this thesis, a series of imine/azo-linked MOPs were synthesized. LÄS MER

  4. 3. Non-aqueous Electrolytes and Interfacial Chemistry in Lithium-ion Batteries

    Författare :Chao Xu; Torbjörn Gustafsson; Kristina Edström; Daniel Brandell; Brett Lucht; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion batteries; electrolyte; electrolyte additives; electrochemistry; interfacial chemistry; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : Lithium-ion battery (LIB) technology is currently the most promising candidate for power sources in applications such as portable electronics and electric vehicles. In today's state-of-the-art LIBs, non-aqueous electrolytes are the most widely used family of electrolytes. LÄS MER

  5. 4. Nanocellulose and Metal-Organic Framework-Based Composites : Synthesis, Characterization, and Applications

    Författare :Shengyang Zhou; Chao Xu; Maria Strömme; Lars Wågberg; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocellulose; Metal–organic frameworks; Nanocomposites; Interfacial synthesis; Porous materials; Energy storage; Water purification;

    Sammanfattning : Nanocellulose is one of the most promising of the green materials available for use in a sustainable economy because of its natural abundance and renewability. Compared to petroleum‒derived synthetic polymers, nanocellulose has many unparalleled advantages such as its unique nanofibrous structure, high thermal stability, mechanical flexibility, rich surface chemistry, biocompatibility, and biodegradability.
