  1. 1. Combining Electrochemistry and Photoelectron Spectroscopy for the Study of Li-ion Batteries

    Författare :Ida Källquist; Maria Hahlin; Håkan Rensmo; Laurent Duda; Kristina Edström; Hendrik Bluhm; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; battery interfaces; electrochemistry; electrochemical potential; photoelectron spectroscopy; operando; ambient pressure photoelectron spectroscopy;

    Sammanfattning : In this thesis photoelectron spectroscopy (PES) is combined with electrochemistry to investigate the electrochemical processes that occur at the electrode/electrolyte interfaces in lithium-ion batteries (LIBs). LIB systems are studied by the use of both ex situ PES, where electrodes are electrochemically pre-cycled and subsequently measured by PES, and operando PES, where electrodes are cycled during PES measurements.

  3. 2. Interfaces in Li-ion batteries seen through photoelectron spectroscopy

    Författare :Ida Källquist; Maria Hahlin; Håkan Rensmo; Laurent Duda; Kristina Edström; Edvin Lundgren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : To accommodate the need for greener energy solutions renewable energy sources aswell as reliable energy storage is a prerequisite. For the latter, high energy densitybatteries with long-term cycling stability are necessary. The cycling properties of abattery is to a large extent dependent on the functionality of the battery interfaces. LÄS MER

    Sammanfattning : This thesis describes different aspects of nanotechnology manufacturing with nanoimprint lithography (NIL), a relatively new nanofabrication tool capable of high resolution and high throughput. Surface structure creation with NIL is based on mechanical deformation of the patterning material. LÄS MER
