For 1D nanomaterials their natural embodiment is as aligned fibres or fabrics that efficiently exploit the axial properties of their constituents. We work with a method to produce macroscopic solids made of 1D nanostructured directly collected as they grow floating in the gas phase. The resulting ensembles are “macromolecular” networks with many superior properties compared to monolithic materials: fibers of carbon nanotubes have tensile mechanical properties above many high-performance polymer fibers; fabrics of CNTs are ideal built-in porous current collectors to eliminate electron resistance limitations in composite battery electrodes, sheets of silicon nanowires are flexible and have high cyclability as lithium-ion battery anodes. </div> <div style="font-size:14px"><br /></div> <div style="font-size:14px"><span style="font-weight:700">Juan J.

His group is focused on methods of synthesis and assembly of 1D nanomaterials, and their application for energy storage and as structural elements. </div> <div style="font-size:14px"><br /></div></h2> <h2 class="chalmersElement-H2"><span style="font-weight:700">Carbon fibers for multifunctional composites</span></h2> <h2 class="chalmersElement-H2"><div style="font-size:14px"></div> <span style="font-size:14px"></span><div style="font-size:14px"><img src="/sv/styrkeomraden/material/kalendarium/PublishingImages/Fang-Liu.jpg" alt="Fang Liu" class="chalmersPosition-FloatRight" style="margin:5px" />Battery weight is one of the critical bottlenecks for electric vehicles. Multifunctionality, for instance integrating energy storage capabilities to structural components, is a key enabling technology in realizing substantial weight savings on the system level. Carbon fibres are widely used as reinforcements in polymer composites, while graphite powders are widely used as negative electrodes in batteries. Thus, using carbon fibres as negative electrodes, together with solid electrolyte and other components, one can build the so-called structural composite batteries. Imaging the doors and hoods of an electric car also store energy! However, almost all carbon fibres were developed from the mechanical point of view; a fundamental understanding on the behaviour of carbon fibres under the dynamic electrochemical and mechanical processes in structural composite batteries, and on the relationship between their performance and microstructure are still largely lacking. We aim to gain a fundamental understanding of carbon fibres in the multifunctional composites.</div> <div style="font-size:14px"><br /></div> <div style="font-size:14px"><span style="font-weight:700">Fang Liu</span> is Associate Professor at the Department of Industrial and Materials Science.
