   Sammanfattning : Lithium-ion batteries are one of the most promising candidates for energy storage in sustainable technologies such as electro-mobility or renewable energy systems. However, at present they are incapable to compete with the combustion engine to power vehicles in terms of capacity, price, and safety. LÄS MER

3. 2. Resonant Soft X-Ray Emission Spectroscopy of Vanadium Oxides and Related Compounds

   Författare :Thorsten Schmitt; Joseph Nordgren; Laurent Duda; Stefan Eisebitt; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; vanadium oxides; Li-battery; cathode materials; copper oxides; soft X-ray absorption; soft X-ray emission; resonant inelastic X-ray scattering; cluster model calculations; Fysik; Physics; Fysik;

   Sammanfattning : This thesis addresses the electronic structure of vanadium and copper oxides using soft X-ray absorption (SXA) spectroscopy and resonant inelastic X-ray scattering (RIXS) at high brightness synchrotron radiation sources. In RIXS incident photons, tuned to the energy of specific absorption resonances, are inelastically scattered leaving behind a low energy valence excitation in the system studied. LÄS MER

4. 3. Functional Polymer Electrolytes for Multidimensional All-Solid-State Lithium Batteries

   Författare :Bing Sun; Daniel Brandell; Kristina Edström; Michel Armand; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer electrolyte; Li-battery; 3D-microbattery; Functionalization; Polyether; Polycarbonate; Copolymer; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Sammanfattning : Pressing demands for high power and high energy densities in novel electrical energy storage units have caused reconsiderations regarding both the choice of battery chemistry and design. Practical concerns originating in the conventional use of flammable liquid electrolytes have renewed the interests of using solvent-free polymer electrolytes (SPEs) as solid ionic conductors for safer batteries.
