  4. 22. Stability Phenomena in Novel Electrode Materials for Lithium-ion Batteries

    Author : Mårten Stjerndahl; Torbjörn Gustafsson; John O. Thomas; Robert M. Kostecki; Uppsala universitet; []
    Keywords : Inorganic chemistry; Li-ion battery; electrode material; intermetallic; AlSb; lithium iron phosphate; lithium iron silicate; photoelectron spectroscopy; Oorganisk kemi;

    Abstract : Li-ion batteries are not only a technology for the future, they are indeed already the technology of choice for today’s mobile phones, laptops and cordless power tools. Their ability to provide high energy densities inexpensively and in a way which conforms to modern environmental standards is constantly opening up new markets for these batteries. READ MORE

  5. 23. Electrochemical characterisations of TiO2 nanotube and lithium-metal electrodes for lithium-based batteries

    Author : Charlotte Ihrfors; Leif Nyholm; Fredrik Björefors; Marnix Wagemaker; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion batteries; titanium dioxide nanotubes; lithium metal electrodes; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Lithium-ion batteries have since their introduction on the commercial market in the early 1990s played an important role within the field of energy storage. In this thesis both titanium dioxide, TiO2, and lithium metal are investigated based on their properties as anodes for lithium-based battery technologies. TiO2 nanotubes with lengths between 4.
