Founded in 2010 and based in Rambouillet, the French start-up Nanomakers has been designing and producing since 2012 patented silicon-based nanopowders which transform the mechanical, chemical or thermal properties of materials. Its disruptive technology has made it possible to triple the energy density of Li-ion batteries anodes, or to lighten and reinforce the mechanical properties of certain materials (metal alloys, elastomers) used in various industrial sectors.
