    The effect of carbon materials on the properties of epoxy
    (Flogen Star OUTREACH, 2015-12-23) Gül, Ayşenur; Kamali, Ali; Fray, Derek
    Nanostructured carbon composites can play important roles in lithium and other batteries. Preparation and characterisation of such composites are therefore important in further development of batteries. Carbon nanostructures including carbon nanotubes, nanoparticles and graphene can economically be produced in molten lithium chloride. The present work reports the influence of the molten salt synthesised carbon nanostructure filler and commercial graphite on the properties of epoxy resin. The carbon materials were incorporated into the polymer matrix to make composites. The carbon-epoxy composites produced were then characterized by a variety of techniques including scanning electron microscopy, x-ray diffractometry, and dynamic mechanical analysis. The thermal and mechanical properties of the nanocomposites were also measured. It was found that addition of carbon materials can enhance the properties of the epoxy matrix considerably.

    Safety and health concerns with lithium-ion batteries
    (Flogen Star OUTREACH, 2015-12-23) Gül, Ayşenur
    The lithium ion batteries consist of positive (inorganic lithium-intercalating compound and negative (lithium-intercalating carbon) electrodes and have an organic liquid electrolyte (a lithium salt in an organic liquid). They store lots of energy in a small and light package. Lithium-ion batteries are widely used in cordless communication technologies and equipment such as laptops, cell phones, and other mobile devices. Despite lithium ion batteries are produced with the high safety standards, plenty of incidents have been reported because of fire and explosion of lithium ion batteries in electronic devices or large vehicles and facilities. Therefore, lithium-ion batteries are optimized to store and release energy with respect to environmental, health, and safety issues. This work summarizes potential hazards and safety recommendations for their commercialization.
