The graphite contribution to automotive


In the automotive industry, Imerys synthetic graphites are prized solutions for the production of lithium-ion batteries used to power new-generation electric vehicles, where they boost energy density and shorten charging times. In hybrid vehicles, Imerys combined graphite-carbon black additives improve electrical conductivity, life cycle, and charge acceptance of advanced lead-acid batteries used in cars equipped with start-stop function and recovery of brake energy and in micro-hybrid cars. Graphites are also used in producing thermally conductive polymers and are used increasingly as a metal replacement in producing automotive parts. In alkaline batteries, highly crystalline Imerys graphite powders boost cathode rings' electrical conductivity, mechanical stability, and processability. Graphite dispersions are used on the inner surface of the battery to increase electrical conductivity and corrosion resistance. Graphite is a key ingredient used in polymer and rubber compounds for the manufacture of electronic device housings, seals and gaskets, friction parts, heat exchangers, parts with high operating temperatures, gas barrier membranes, high voltage cables, where reinforcement, electrical and thermal conductivity, lubrication and wear resistance are key parameters. Natural and synthetic graphite are also excellent solutions for hot metal toppings due to their good size distribution and thickness, purity, oxidation resistance, and thermal conductivity. Other applications for graphite include fuel cells, brake pads, carbon brushes, supercapacitors, heat-exchange foils, sintered ceramics, hard metals, refractories, pencil leads, lubricants, can coatings, catalysts, and synthetic diamonds. Imerys is committed to contributing to the shift towards clean and green energy sources other than fossil fuels and will continue investing R&D resources in developing battery and energy storage technologies solutions.
