  1. 1. Probing Critical Interfaces in Dual-Ion Batteries : The Road Towards Performant Graphite Cathodes

    Författare :Antonia Kotronia; Kristina Edström; Tobias Placke; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dual-ion batteries; graphite; cathode-electrolyte interface;

    Sammanfattning : Transitioning into a zero-emission society will require massive efforts with respect to the harnessing and storage of renewable energy resources. The development of large-scale, electrochemical energy storage systems based on abundant and environmentally benign compounds is seen upon as a key factor for guaranteeing a successful outcome.

  3. 2. Transition metal dissolution from Li-ion battery cathodes

    Författare :Yonas Tesfamhret; Reza Younesi; Erik J. Berg; Mark Huijben; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion battery; Lithium-ion cathode; Transition metal dissolution; Atomic Layer Deposition; Inductively coupled plasma atomic emission spectroscopy; Cathode-electrolyte interaction; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : Lithium-ion batteries (LIBs) have become reliable electrochemical energy storage systems due to their relative high energy and power density, in comparison to alternative battery chemistries. The energy density of current LIBs is limited by the average operating voltage and capacity of oxide-based cathode materials containing a variety of transition metals (TM). LÄS MER

  4. 3. Insights into Li-ion Battery and Stainless Steel Interfaces Using Refined Photoelectron Spectroscopy Methodology

    Författare :Sara Malmgren; Kristina Edström; Håkan Rensmo; Daniel Abraham; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : If sacrificing some of its material to form a passivating layer at the surface, materials may expand the range of environments where they can be used and further material degradation can decrease. This thesis aims to contribute with insights into passivating layers on especially Li-ion battery anodes (solid electrolyte interphase, SEI) but also on stainless steels, as well as the non-passivating Li-ion battery cathode/electrolyte interface layers (solid permeable interface, SPI).
