  4. 2. Development and Characterisation of Cathode Materials for the Molten Carbonate Fuel Cell

    Author : Athula Wijayasinghe; KTH; []
    Keywords : molten carbonate fuel cell MCFC ; MCFC cathode; LiFeO2-LiCoO2-NiO ternary compositions; electrical conductivity; porous gas diffusion electrodes; polarization; electrochemical performance; post-cell characterization;

    Abstract : Among the obstacles for the commercialization of the MoltenCarbonate Fuel Cell (MCFC), the dissolution of thestate-of-the-art lithiated NiO cathode is considered as aprimary lifetime limiting constraint. Development ofalternative cathode materials is considered as a main strategyfor solving the cathode dissolution problem. READ MORE

  5. 3. Structural Changes in Lithium Battery Materials Induced by Aging or Usage

    Author : Rickard Eriksson; Kristina Edström; Torbjörn Gustafsson; Leif Nyholm; Marca Doeff; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Li-ion batteries; XRD; EXAFS; HAXPES; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Li-ion batteries have a huge potential for use in electrification of the transportation sector. The major challenge to be met is the limited energy storage capacity of the battery pack: both the amount of energy which can be stored within the space available in the vehicle (defining its range), and the aging of the individual battery cells (determining how long a whole pack can deliver sufficient energy and power to drive the vehicle).

  7. 5. Exploring Reaction Pathways in Li-ion Batteries with Operando Gas Analysis

    Author : Robin Lundström; Erik Berg; Reza Younesi; Isidora Cekic-Laskovic; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Online electrochemical mass spectrometry; Li-ion batteries; Solid electrolyte interphase; Reaction pathways; ; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : The reliance on Li-ion batteries is increasing as we transition from fossil fuels to renewable energy sources. Despite their widespread use, a gap remains in understanding certain processes within these batteries, especially regarding the solid electrolyte interphase (SEI) and the impact of side reactions on Li-ion batteries.
