  1. 1. Atoms in Lithiated Carbon Fibres

    Författare :Marcus Johansen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lithium insertion; atom probe tomography; synchrotron hard X-ray photoelectron spectroscopy; energy storage; carbon fibres; Auger electron spectroscopy; microstructure; heteroatoms; multifunctional composites;

    Sammanfattning : Carbon fibres are key constituents of structural batteries, in which electrochemical energy storage and mechanical load bearing are merged in one multifunctional device. Here carbon fibres simultaneously act as structural reinforcement by carrying load and as battery electrode by hosting lithium (Li)-ions in its microstructure. LÄS MER
