4. 8. The Challenge of Probing Lithium Insertion Mechanisms in Cathode Materials

   Författare :Jonas Höwing; Torbjörn Gustafsson; Christian Masquelier; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Li-ion battery; cathode materials; insertion mechanism; single-crystal X-ray diffraction; vanadium oxide; lithium iron phosphate; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

   Sammanfattning : The Li-ion battery has, from its commercialisation in the early 1990's, now become the most widely used power source for portable low-power electronics: laptops, cellular phones and MP3-players are a few examples. To further develop existing and find new electrode materials for these batteries, it is vital to understand the lithium insertion/extraction mechanisms taking place during battery operation. LÄS MER

5. 9. Lithium iron phosphates as cathode materials in lithium batteries

   Författare :Anna S. Andersson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; lithium batteries; cathode materials; lithium iron phosphates; magnetic properties; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : Iron-based oxides are perhaps the only realistic cathode materials for electric and electric-hybrid vehicle applications. Two types of lithium iron phosphate, LiFePO4 andR-Li3Fe2(PO4)3, have been investigated for use within the lithium/lithium-ion polymer batteryconcept. LÄS MER

7. 10. Low-Cost Iron-Based Cathode Materials for Large-Scale Battery Applications

   Författare :Anton Nytén; Josh Thomas; Jean-Marie Tarascon; Uppsala universitet; []
   Nyckelord :Inorganic chemistry; Li-ion battery; cathode material; lithium iron phosphate; lithium iron silicate; X-ray powder diffraction; Mössbauer spectroscopy; photoelectron spectroscopy; Oorganisk kemi;

   Sammanfattning : There are today clear indications that the Li-ion battery of the type currently used worldwide in mobile-phones and lap-tops is also destined to soon become the battery of choice in more energy-demanding concepts such as electric and electric hybrid vehicles (EVs and EHVs). Since the currently used cathode materials (typically of the Li(Ni,Co)O2-type) are too expensive in large-scale applications, these new batteries will have to exploit some much cheaper transition-metal.
